Why Does My Laptop Audio Stop Working When I'm on Battery Power?

I found the same problem in Windows 7. I think its not due to low power, but rather due to a software bug. After I installed Windows 7 Service Pack 1, my problem was solved

1. Ubuntu 18.04 Won't Boot on Battery Power

This link worked for my HP laptop.1) Modify the GRUB_CMDLINE_LINUX_DEFAULT kernel variable in /etc/default/grub:2) $ sudo update-grub 3) Reboot.dis_ucode_ldr stands for "disable microcode loader"

2. can i get power from a car battery to power a lamp, or a small dvd player?

yea its called a converter

3. Which is the best smartphone to buy that has speed, storage, battery power and looks?

The answer to this question Varies with the Budget

4. Can I use a car battery to power a plug outlet? If so, how?

Yes its easily possible. It just requires purchasing a power inverter that is large enough to handle the grinder under load and has battery clips to clip directly to the battery. If you do not have a power inverter already you can get them at Walmart, Harbor Freight, and most automotive stores also carry them. Also Home Depot carries some pretty nice ones also. I personally have a Husky 750Watt from Home Depot and it is fan cooled dual outlet and has low battery shut-down protection which is great if you use it from your vehicle battery. If you have further questions email me at .

5. Can't disable dynamic contrast on laptop when on battery power

Start the "Intel Graphics Control Panel" app, click on the "Power" icon at bottom, click the "On battery" to the left and click the "Disable" checkbox under the "Display power saving technology"

6. How can i save battery power on my cell phone?

lock it, turn off blue-tooth and only use it when you need too. put it into power-save mode. hope this helps

7. How much battery power does monochrome mode save in Android power saving?

Actually.... Umm! Not so much.When the display is an AMOLED or POLED or OLED, it will save a little, because of those dark pixels. But it wo not be so noticeable/significant.Because, the image processor processes the images in color. It is only the display that shows in monochrome. The image processor (in SoC) produces the same color image and works and consumes as the same way if the display was in Color mode.To check this.Enable Monochrome/Grayscale in your PhoneTake a Screenshot in anywhere(in any app/any screen) of the B/W displayNow, turn off Monochrome (re-enable the Color mode/Normal mode) and see the Screenshot,.... You will find that the image is in Color. Not B/W.

8. Why is my Honda slowly draining battery power?

your alternator isnt charging or at least not enough. you should have 13 to 14 volts when running. if it was shorting that much something would have burnt by now. check your alt, voltage reg and alt belt

9. How much time can I get from a battery power source?

Your other answer is correct, but I think the speaker box will possibly operate on 12 volts instead of 16 volts, at reduced speaker power. You do not have enough data to calculate how long the battery will operate. .

10. 78 honda civic has power at battery , but no power any where else. ground wire and positive wire is good.Why?

Look for a fusible link in the pos cable, make sure connection are clean and secure. Good Luck

11. Why can't we use solar energy or a large rechargable battery to power certain household items?

Why dont you just use a pedal generator? Same idea, and its a great work out. Heres an answer... You can do it. You just have to work out the specs and set up the wiring yourself so that it would work. Plus Solar panels and rechargable batteries are a little costly so it may take a couple years or even a decade to recoup the money spent.

12. Is it true that most things that come to you are bad things or things that you usually don't want, and the good stuff you have to go and get for yourself?

Well, this is because you do not go out and get the bad things for yourself, not of your own free will, though your own actions often invite them, or set the stage for them.The good things often falls out of the sky for you, too. But if you believe that you must go out and get them, then you might miss them when they come to you. Often good comes in a different form than you expect. And misfortunes build strength each time you face them and overcome them.Looking back on today, I laugh inwardly. I finally took my old truck out for a test drive, round out the tires, and blow the moisture out of the engine. It runs like a top. I replaced the float valve assembly in the carburetor (1961 Chevy 3/4 ton) a month or so ago and it runs fine. I went about 3 miles, turned around in a gravel lot, and the engine quit. Plenty of battery power to restart but no joy. The carb leaked in a few places, which told me the float tank was flooded. I did not bring my toolkit, but had a screwdriver, removed the carb top, flicked out the gas, and monkeyed around with the floats and valve without taking the tiny parts apart, put the carb together and drove home.Funny how familiar surroundings look alien, and the blue sky seems suddenly infinite and empty when one is stuck on a country road, with no intention of having my ride come to this. I search back for some redeeming or comforting feeling, and fine none. Do I feel stronger? No. But I guess other problems helped me deal with this one. I employed prayer of course, and managed to sidestep that feeling of defeat. Is it true that most things that come to you are bad things or things that you usually do not want, and the good stuff you have to go and get for yourself?

Check Engine Light Went Off by Itself. still Get It Checked?
If the light went off then it means that whatever monitor failed was tested again and passed. However I would still have a shop check out what code was set just in case since the computer will store it as long as battery power is not removed. This could be an early sign of a system beginning to fail or it could be as simple as a loose gas cap.1. I sell art at outdoor shows. I've seen people use a boat battery to power lights, but I need instructions.You need a deep cycle marine battery and a "Low Current Draw" inverter. I would not use halogen lighting because of the amount current it draws2. Can I use a car battery to power a plug outlet? If so, how?Yes you will have to buy an inverter that converts 12VDC to 120 AC. 7 Amps at 120 volts is going to equal to approximately 840 watts: So you are going to need at least a 900 to 1,000 watt inverter. If you can not find on at your local auto parts dealers you can find them at most TSA truck stops. or travel stores at most big Truck stops. You can also fight them at truck dealers. I mean by that dealers that sell 18 wheelers like Peter Built, Kenworth. Internationals. The biggest I have seen in truck stops was a 5,000 watt unit. That thing could almost power a whole house. 1,000 watt units are fairly common in trucks now days because most drivers have refridgetors in their trucks, entertainment centers and computers in their trucks, and instead of running their engines all night they use electric blankets when it is real cold. Plus a lot of them have small electric stoves so they can cook and not have to pay the high prices at truck stop restaurants. You will also need a battery charger to charge up your battery between uses Not cheap rinky dink one, a good one. It might cost you more money up front but cheaper in the long run. Another place I just thought of you can look is at your local R.V. dealers (Travel trailers) They use a lot of 12 volt self contained appliances like air conditioners, ice boxes, They also do it the other way and have inverters to convert 12VDC to 120 VAC..3. laptop only uses battery power when its charged?go to the Acer service station. your adapter do not have problem neither your battery. a device that hand the adapter and battery power seems to be not working. get it checked4. 1989 GMC C1500 headlamp relay loaction?There is no relay for the headlights on a 89 gmc. The breaker is built into the head light switch. You can check for a bad fuseable link at the junction block under the plastic cover under the hood on the passenger side. The fuseable link is black where it bolts to the block and then the wire turns red after the fuseable link. Red wire at terminal d on the headlight switch connector is battery power for the headlights. Power comes out on yellow wire terminal c of the headlight switch and then to the dimmer switch and then to high and low beams. If you have no high or low i would look into a bad headlamp switch i have probably put 50 of um in in my 10 years as an auto mechanic.5. Do powered subs (ones that plug into the battery for power) for cars work as well subs run through an amp?Powered subs are basically just kits that come with everything you need. They still have an amp but it is hidden in the enclosure. Thus they can sound exactly like buying component subs and an amp seperatly. if you can find a good powered sub system then yes it would be a good buy. however most powered sub systems are not very good quality and do not sound very good. it would probably sound the best to get a sub, amp and enclosure seperatly. as for improving your speakers, i would look into getting a 4 channel amp for them. with an amp your speakers will be louder and the sound will be less distorted. you would most likely need aftermarket speakers for that though. good luck!!!!

Protecting Microcontroller Input Pins from Soft Power SwitchThe circuit linking the battery, microcontroller signals and the SHDN* input of the regulator (renamed EN) seems dodgy.How about using a latch (running on battery power) to capture the closure of the key. Then the output of this latch can be OR'ed with a signal signal from the MCU to drive the SHDN* pin of the regulator (renamed to EN in the schematic). Upon booting, the MCU should drive its enable line first, then clear the latch, thereby ensuring that EN stays asserted.The subsequent button action can be monitored through the latch: if the switch is pressed again, the latch goes high again. The MCU notices this and clears both the latch and its enable signal, triggering shutdown. Since the switch is latched, the MCU can monitor this very conveniently by simply polling it at a leisurely frequency.One more optional refinement would be a circuit to ensure that when the battery itself comes online, the system powers up without the use of the button. This could be some kind of pulse which sets the latch.8. How long can a 68 aH battery power a 1500 watt appliance?nicely, a fifteen Watt photograph voltaic panel working for an universal of 12 hours in line with day, (there will be clouds), will placed 15 * 12 = a hundred and eighty Watt-hours into the battery.

Build a Building Automation System That Can Run on Battery Power for Decades
With the industry-leading low-power MSP microcontroller, Texas Instruments (TI) has been committed to helping engineers solve various problems in developing and building building building automation applications. Ti's MSP MCU not only has very low power consumption, but also has a high degree of analog integration to achieve miniaturization. At the same time, it includes reference software and industry standard communication protocol. So, what do these advantages and characteristics mean for the design of building automation?low power consumptionUsing MSP MCU, engineers do not have to sacrifice functionality in building automation systems or charge batteries. By combining low-power design technology with energy harvesting, battery replacement in thousands of remote sensors can be reduced or avoided. In case of battery replacement or power loss, the system state can be maintained due to the speed and durability of FRAM and compute through power loss (ctpl) software facilities. In fact, the application can be reconnected immediately where it was interrupted without recalibration or hard start. With energytrace ™ With the real-time power distribution capability of the technology, the optimized MSP microcontroller can make full use of all the power of the application.Intelligent simulation integration and miniaturizationMany people may not understand the real meaning of "MSP". This name actually represents "mixed signal processor". One of the main objectives of Ti is to integrate analog peripherals to reduce the complexity, size and cost of building automation system. The integrated high-performance simulation function allows engineers to add local interface connectivity to each sensor in the building automation system, so as to realize functions such as sampling and processing.Reference software and connectivity protocolWhether wired or wireless connectivity is added to the building automation system, MSP MCU hardware and software can make the device run like a host controller and seamlessly connect with multiple connectivity solutions at the same time. Ti also provides Ti design reference designs, wired and wireless stacks and algorithms, including the recently released ctpl and iqmathlib libraries, to speed up development and reduce the required connectivity (RF) expertise.Below, we will list some of the most common building automation applications to see how low-power MSP MCU meets their design needs.Occupancy sensors and motion detectors are essentially sensing applications, including a series of technologies for detecting the number of people in a fixed area. Usually, this detection is automatic and unknown to the detected person. Sensing technologies such as infrared (IR), ultrasonic, sound and image recognition applied in areas such as offices, classrooms, conference rooms, bathrooms, storage rooms or corridors. These sensors or detectors can be used to save and save power and energy, while also helping to add intelligence and data analysis to improve the security situation in the building.MSP MCU can provide the following advantages for occupancy sensor applications:-Low power consumption for simpler power supplies-Miniaturized size for size constrained applications-Integrated intelligent simulation function for passive infrared (PIR), thermocouple, inductance, ultrasonic and other sensor inputs. For example, the 14 bit high-speed ADC on msp432 MCU can be used for advanced capture algorithms and improve performance-Aes256 and IP encapsulation for enhanced system security-Nonvolatile embedded fram for firmware upgrade and data loggingIn addition, MSP MCU also supports 6LoWPAN and simplelink ™、 Multiple communication stacks such as KNX.Electronic lock (e-lock) is a mechanical and electronic closing device that can be opened by providing confidential information or combination by entities such as key, door card, digital keyboard, fingerprint, RFID card and security token. These products are mainly used to help improve security to ensure legal access to specific areas.MSP MCU can provide the following advantages for e-lock applications:-Ultra low power consumption that can be operated by battery for more than 10 years-Aes256 and IP encapsulation for enhanced security and IP protection-Nonvolatile embedded fram for firmware upgrade and data logging-Support multiple communication stacks, including near field communication (NFC), 6LoWPAN and Bluetooth ® Low energy (ble) and Wi Fi ® Simplelink et alGlass crack detector is a detector that can detect whether a window is broken or damaged. It is usually used in applications such as electronic anti-theft alarm. The glass crack detector generally monitors the noise or vibration from the glass through the microphone. If these vibrations exceed a specific threshold, the detector circuit analyzes these vibrations.MSP MCU can provide the following advantages for glass rupture detector applications:-Ultra low power consumption that can be operated by battery for more than 10 years-Reference design and software, with robust algorithms for error triggering or monitoring-Higher security achieved by aes256, local security zones for IP protection, and firmware upgrades-Low power 14 bit high speed ADC for advanced capture algorithms and higher performance
How Can I Save Battery Power on My Cell Phone?
turn it on only when you need to use it. dont keep it on all day1. If I buy the right equipment, can I use a car battery to power on my PS3 and TV?It wo not work. I do not know how much power a PS3 draws, but any TV big enough to really watch draws too much current for a car battery. And, you need a power inverter, not an alternator. The alternator is what keeps your battery charged in your car. The inverter converts DC to AC.2. A question about the canon powershot camera..?I am not aware of any PowerShot camera that has a firewire port on it. So if you buy a firewire cable for it, you will be left with a cable that you can not use to connect your camera to the computer. A USB cable is what you need. A card reader is a better option though. It saves battery power and overall makes getting files off the memory card much easier and faster.3. How long will my CPAP last on a Duracell Powerpack 600? Back up battery, power soure / C-Pap?call your DME rep for answers4. Can a car battery power a laptop PC?I do not think so, while many laptops are 12 VDC and so are car batteries, the amount of amps in a car battery would most likely destroy your laptop. This is unresearched, but I have worked with electronics and cars and I do not think it would work directly. Mentioned above are power inverters which do work, but it's not direct as I think you are thinking of.5. How to heat wire using battery power?The problem is that to generate heat you need power. Electrical power is Voltage times Current. So to get 120 watts of power, with a 120 volts AC requires 1 Amp, to get 120 watts of power with a 12 volt battery requires 10 Amps. The next problem is that with DC power you get a significant voltage drop over the connecting wires and the higher the current the higher the voltage drop, and the more loss. If you are looking to heat something to 100 degress very quickly then you need not hundreds of watts but thousands of watts, especially if the temperature is below freezing. If I am trying to start my car in the winter I need to draw around 60 Amps from the 12 volt battery or about 720 watts. It does not take very long to drain a battery if the car does not start quickly. On a really cold day if the battery has set out all night about 10 minutes. I assume that you are talking Fahrenheit and not Celsius in temperature. You would have to check with a supplier to find out how long a heat tape will take to melt snow. Normally we are talking a period measured in portions of hours or hours depending upon the temperature and the depth of the snow. If the snow is too deep, then the wire will melt snow and form a cave with the snow above the wire. Depending upon the surface that the wire is on, you may have difficulties heating it up to 100 degrees at spots while others are at a temperature below freezing. A shingle roof may handle it, but some plastics or metals may eventually fail. If you can wait until a sunny day to melt the snow there are passive solar methods to melt snow, maybe you should investigate them. Also to melt snow, you do not need 100 degrees, even heating to 40 degrees Fahrenheit will melt snow slowly. I would suspect that if you had an inverter that changes DC to AC with a sufficient number of batteries in parallel that you could run the heat tape for a while to melt snow off of a small object, but then you have to charge the batteries. You could also consider getting a small gas generator to provide power to the heat tape. Good luck.6. Does reseting an ipod costs battery power?No not that i know of. It is not suppose to lose any of the battery life. Make sure your stuff is charging properly and that you dont have an old drained battery
10 Brilliant Gifts for the College Kid in Your Life
What Is a Smart Doorbell and How Does It Work?Smart doorbells go beyond basic visitor notification, bringing convenience and safety features like answer-from-anywhere and a live video feed.A smart doorbell is an internet-connected replacement for a traditional doorbell. It can "ring" a smartphone or other device in your home, and integrate with a smart home automation system to display real-time video from your front door. Note that "smart doorbell" is virtually synonymous with "video doorbell" because most have video cameras included - something to watch for if you are researching. Doorbells, of course, notify you of a visitor's arrival. Smart doorbells expand on that basic function while bringing new convenience and safety functions to your front door.Smart doorbells are a lot like security cameras, only with a button visitors use to get your attention. When visitors push the button you will get a notification on your smartphone or other device, whether you are home or out and about.Most smart doorbells offer real-time video and two-way audio, which gives you some options. You can still answer your door, but you will have a little more information.Because you know who's there, you can: 1. Decline to answer the door if you are home; 2. Leave the door shut but talk to them via two-way audio on your smartphone (similar to an intercom) no matter where you are; or 3. With certain smart doorbells like Eufy's Video Doorbell, play a pre-recorded message like, "You can just leave it, thanks!" Screening your visitors or answering the doorbell from anywhere with your smartphone is not only convenient, but also a safety feature. You are not giving away whether you are home or not. And you do not have to open your door.Smart assistant integration and voice commands can enhance your door-answering experience. Using an Alexa voice command, such as: "Alexa, show me the front door," Arlo's Video Doorbell can send its live video feed to Amazon Echo devices with a screen. Google's Nest Hello also display its video feed with voice commands, and can be set up to automatically send its live video feed to a Nest Hub screen when a visitor presses the doorbell button.Smart doorbells are basically security cameras with additional door-answering features, so here are some smart doorbell security camera functions. Smart doorbell cameras with AI (artificial intelligence) person recognition can filter out "false positives" so you do not get a bunch of motion alerts for tree branches on a windy day. More advanced AI systems are not only better at recognizing people versus general motion, but can even identify familiar faces and package deliveries.When choosing a smart doorbell, one significant question is whether to go with built-in memory versus cloud video storage. Google Nest requires a subscription and cloud video storage to enable many of its features, for example, but stands out with its 24/7 continuous recording. Most other cloud services only record short clips when motion or sound are detected. It's good to have a cloud backup in case the camera is stolen, but it also sends your data outside your network while using internet bandwidth to do so. Conversely, the Eufy Video Doorbell exclusively uses 4GB on-board storage to maintain up to 30 days of footage to keep your data local, but it's more susceptible to theft. Subscription costs are another factor with cloud storage services, and we will cover that one a bit later.Smart doorbell power sources generally fall into three categories: GFCI outlet plug-in, batteries or low-voltage wiring (or a combination of wired plus battery backup). It's important to know your installation options; not every home has outlets near enough to the front door, or working low-voltage wiring.The Nest Hello can be wired to low-voltage wiring (16-24V AC) or plugged into a regular outlet with a power adapter (100V, sold separately). The Ring Doorbell 3 can run exclusively on its rechargeable battery pack or hook up with optional wiring. Battery power generally makes for the easiest installation because there's no wiring to worry about, but the size will also tend to be a little larger to contain the batteries.For any power source options, installation is pretty simple. Generally you will just affix the housing onto a wall and then put on the cover.With some smart doorbells, you will need to decide whether you want to pay for a video storage subscription service.The Nest Hello is $230 and requires a subscription to get Nest Aware functionality (essential to get the best features) and cloud video storage. You will pay $5/$10/$30 per month for Nest Aware and 5/10/30 days of video storage.The Arlo Video Doorbell costs around $150 plus a $3 per month optional subscription (again, pretty much essential).Ring Doorbell 3 models range from $100 to $230, and subscription tiers cost $3 to $10 per month.The Eufy Video Doorbell has options from $160 to $200 and is fully functional with its local storage. It offers additional online storage options ranging from $3 per month per camera to $10 per month for up to 10 cameras.

People like you piss me offHow is valuation of a free app done?We usually look at the app's current profit and its profit potential to determine its value. A free app can still generate profit via in-app purchase, advertising & affiliate. If the profit trend is stable and all other analytics user data looks healthy and sustainable, I usually give it a 12x - 30x monthly profit valuation. If the app is not generating any revenue, it will be much harder to give it an accurate valuation. However, we can look at its future profitability potential. For example, if the app has a huge amount of downloads, users, sessions or a high retention rate, the app could potentially make money by placing ads, adding in-app purchase, doing affiliate marketing, changing business models, etc. In this case we will do an estimation on how much the app could make if some of the monetization has been done, then deduct the cost of making that monetization method possible.The secret about app valuation is that it really depends on who the buyer of that app business is. If the buyer has the skills or resources to increase the profit of the app, he/she might give a much higher valuation than someone who does not have that. That's when App Brokerage Service comes in. A broker can reach out to a targeted group of buyers who might value the app higher and negotiate on the deal. However, brokers only work with high value sales, usually apps that are making more than $1000/mo or could be sold for more than $50,000. If the app is smaller than that, you can also test out it's market value by starting a free auction on Flippa's app marketplace, where lots of buyers are bidding on apps everyday. You can also compare the price of similar apps sold before to determine the value of your app.How is valuation of a free app done?How is valuation of a free app done ?.11 Best disco ball apps for Android & iOS | Free apps for Android and iOSA virtual disco ball is a familiar thing for everyone in a new modern form.

The only advice I give on backpacks has to do with weight. Few years ago I went to replace my pack, found a real nice one, had all the features I wanted. This pack cost $285 and weighed 8 and 1/2 pounds empty. I found a pack the same size, same features, cost $75, and weighed less than 3 pounds. The less expensive pack wo not last as long as the other one, but I do not have to carry an extra 5 pounds every time I go backpacking. With the difference in price I can afford to replace the lighter pack several times before it cost me as much per mile as the heavier one. Over 35 years backpacking experience, more than a 1,000 nights in the back country.
Now, 'green' Li-ion Battery Powered by Ancient Red Dye.
Washington, December 12 ( ANI ): Researchers including Indian origin scientists have developed a non-toxic and sustainable lithium-ion battery powered by purpurin, a dye extracted from the roots of rose madder plant (Rubia species).More than 3,500 years ago, people in Asia and the Middle East first boiled madder roots to color fabrics in vivid oranges, reds and pinks.The breakthrough suggests rose madder - a natural plant dye once prized throughout the Old World to make fiery red textiles -could lay the foundation for an eco-friendly alternative to traditional lithium-ion (Li-ion) batteries.To develop the new 'green' battery, chemists from The City College of New York teamed with researchers from Rice University and the U.S. Army Research Laboratory.Traditional Li-ion batteries charge everything from your mobile phone to electric vehicles, but carry with them risks to the environment during production, recycling and disposal."Purpurin," on the other hand, said team member and City College Professor of Chemistry George John, "comes from nature and it will go back to nature." Most Li-ion batteries today rely on finite supplies of mined metal ores, such as cobalt.The cobalt salt and lithium are combined at high temperatures to make a battery's cathode, the electrode through which the electric current flows.Mining cobalt metal and transforming it, however, is expensive, explained Dr. Leela Reddy, lead author and a research scientist in Professor Pulickel Ajayan's lab in the Department of Mechanical Engineering and Materials Science at Rice University.Fabricating and recycling standard Li-ion batteries demands high temperatures, guzzling costly energy, especially during recycling.Production and recycling also pumps an estimated 72 kilograms of carbon dioxide - a greenhouse gas - into the atmosphere for every kilowatt-hour of energy in a Li-ion battery, he noted. These grim facts have fed a surging demand to develop green batteries, said Dr. Reddy.Fortunately, biologically based color molecules, like purpurin and its relatives, seem pre-adapted to act as a battery's electrode. In the case of purpurin, the molecule's six-membered (aromatic) rings are festooned with carbonyl and hydroxyl groups adept at passing electrons back and forth, just as traditional electrodes do."These aromatic systems are electron-rich molecules that easily coordinate with lithium," explained Professor John.Moreover, growing madder or other biomass crops to make batteries would soak up carbon dioxide and eliminate the disposal problem - without its toxic components, a lithium-ion battery could be thrown away.Best of all, purpurin also turns out to be a no-fuss ingredient."In the literature there are one or two other natural organic molecules in development for batteries, but the process to make them is much more tedious and complicated," noted Professor John.Made and stored at room temperature, the purpurin electrode is made in just a few easy steps: dissolve the purpurin in an alcohol solvent and add lithium salt. When the salt's lithium ion binds with purpurin the solution turns from reddish yellow to pink. Remove the solvent and it's ready."The chemistry is quite simple," coauthor and City College postdoctoral researcher Dr. Subbiah Nagarajan explained.The team estimates that a commercial green Li-ion battery may be only a few years away, counting the time needed to ramp up purpurin's efficiency or hunt down and synthesize similar molecules.The team reported their results in the journal Nature's online and open access publication, Scientific Reports.

The Electric Blanket in a JACKET: Battery Powered Clothes Stop You Feeling the Cold by Reaching a Ve
Do you dread winter? Hate stepping outside because no matter how much you wrap up, you end up freezing?Then a new range of heated clothing could be the answer to all your woes.TechNiche has launched a selection of clothes that can heat up to a toasty 60°C.The IonGear battery-powered vests, jackets and gloves use lithium batteries and carbon filaments to generate heat and are adjustable so a wearer can choose the temperature according to the weather.Its makers say the clothing is aimed at those who work outdoors, exercise outside, compete as an athlete in extreme weather or just feel the cold very easily.After stepping back indoors, a user simply recharges the battery and the garment is ready to use again the next day.The vest and jacket contain three pads - one in each front side and one across the lower back - fitted to a 7.4V battery and have a temperature controller with three settings - low (40°C), medium (50°C) and high (60°C).The clothing starts to warm up within one or two minutes of being switched on and can stay warm for up to nine hours, depending on what temperature you set it to.The battery fully recharges in around four hours and has around 500 charges in it.The heating elements, battery and temperature controller can all be removed to wash the clothing.The gloves have heating elements built into them which run along the back of the hand and each finger, and each glove has its own battery and multi-level temperature controller with four settings ranging from 32-57°C.A spokesman for TechNiche said: 'We have the solutions you need to beat the cold while at work, rest and play.'We offer products that allow you to work longer in extreme cold conditions, keeping your mind on the job and helping you perform better.' As well as its heated products, TechNiche has grown to become one of the largest manufacturers of cooling vests in the world.The cooling vests are used by top athletes including Formula 1 teams, ProCycling teams and several national football teams in the Brazil World Cup last year.The vest costs £151.10 excluding VAT, £176.10 for the gloves and £194 for the jacket.
