If you're looking for USB wall-charger you might want to give these 5V/2A chargers a try.
Thanks. Not unless someone who's tried it can advise. I tried a 1 Amp usb wall charger plugged into the micro usb port on the tablet and it got very hot so I pulled the plug. The Kindle Fire HD charges from a 2 Amp wall charger, I know. (The fast charger they sell for it is 1.8 Amps so assume 2 Amps would be safe.) But I can't get a straight answer on the Lenovo devices for some reason. And it's not in their documentation, either.
