As I mentioned earlier, when my Chinese (Laser) ereader went completely flat it wouldn't charge when plugged into the computer, and I am assuming that this was because the light had caused it to discharge faster than it charged. I thought the reader was completely dead - and the battery obviously was - so I got a very pleasant surprise when the wall charger worked.

The difference between charging the reader with a computer and charging it with a wall charger is that you can alter the settings (or even read an ebook, for that matter) when it is plugged into the wall charger, and you can't when it is plugged into the computer.

Unfortunately, unless you can get hold of a wall charger cheaply there is a risk you would be throwing good money after bad!
