The adapter for my tablet died yesterday. It burned after only 13 hours work. Now I need a new charger and I have no idea what the polarity on the center pin is. So, could someone please check if the center pin has positive or negative polarity? I have an M70003 but maybe the poliarity is the same on all models?

Hmmm.... sad. My M001s charger died too. I bought a universal charger (3-12 V 1500 mA) and it has exchangeable plugs. I can connect the plugs two way (+- or -+) so i can change the polarity too. The charger works fine with my M001. I think you can buy a universal charger anywhere just watch the V/mA to fit your device.
