Following is the detail:
5.3 Vdc @ 200mA
5.3 Vdc @ 1.1A
5.3 Vdc @ 150mA
Based on the above info, I built a car charger, computer charger, solar panel charger for my Touchpad. The Touchpad is charging (lightning bolt icon displays).
You can buy any micro USB car charger (or micro USB cable) on eBay (as long as output is 5 VDC +- 5% and minimum 400ma), modified so data line is 2.6 Vdc.
If your Touchpad at Off mode, you can use car charger or even PC USB port to charge Touchpad.
I did charged on PC and car charger for a week without any issue. Also successfully with Solar panel (Output 5Vdc @ 800 mA).
Again, fyi only if you want to build one for yourself. Beware that many ad. for TOUCHPAD car charger (only power to Touchpad but without charging battery). If you decide to buy one, ensure to ask for TouchPad battery charger, NOT TRICKLE Charging as advertise.
Touchpad required 2.6 Vdc present at data line to switch to charging mode. Without switch to charging mode, any input power to power lines in TOUCHPAD just as a supplemental voltage.
Better off to build one for you or wait for a while before resellers modify as schematic below. Do not waste money to buy something that will not work. Touchpad needs build in circuit below in usb cable/cigarette adapter to switch to charging mode.
1st image is the schematic
2nd image is charging with car charger (look for lightning bolt icon).
3rd image is charging with homemade AC adaptor.
4th image is connect with solar panel...under fluorescent light so not enough output to charge unit.
