It's not a Microsoft product. You need to talk to Best Buy.
What kind of power adapter does my 10'' Windows tablet need?

My brother recently purchased a generic 10'' Windows tablet from Best Buy. Everything works great, except that the power supply is not giving the tablet enough power to keep it charged. Even when the tablet is plugged in, the power slowly drains.
The tablet did not come with a power supply. It charges through micro USB. The adapters we have do charge the tablet, but too slowly to keep the tablet from draining if my brother is using it. What should we do?

2015-03-20T00:33:53+00:00 I'm sorry if I offended you. Microsoft sent me an email asking me to review the answer I received. The answer was very short, and did not contain the helpful detail you provided, HairyFool. I answered honestly.
It's worth mentioning that if you are going to respond to posts by calling customers "snotty," customer service (in this case, providing a Microsoft customer with an answer to a question) might not be the area where you should concentrate your efforts.

2015-03-05T07:29:12+00:00 Power demand depends on the specification and design of the tablet which from the OP cannot be determined, there is no such thing as a "generic Windows tablet".
What power is consumed by the display, CPU? Newer models use less than older ones. What technology is in the RAM & SSD? Again the power demand is different. How big is the battery? How long does it last? What is the stated recharge time? Can you use it whilst charging?
All this defines the requirements of the PSU and has nothing to do with Windows, you could wipe of Windows and install Linux, the problem would be the same.
The fact is USB connectors are actually completely inappropriate for a charging connector for this type of device but it is a cheap tablet because it uses cheap components. It came with a USB charger, that should be limited to 2A at best, probably less for the micro-USB connector in the chassis, Windows does not limit that.

Here is the tablet I'm talking about:

There are clear specifications for the USB interface which limits the amount of power the USB interface can draw. If the tablet can demand more that a standard USB port can deliver that is a design error that could only be covered by a specific supply that should have been included with the device.
Nominally 1A for USB although there are some sold that state that they can support 2A, you would need to look for that specification through whatever supplier is available to you in your region.
