STOP!!! STOP! STOP! STOP!

As a electronic design engineer I can only highly recommend to NEVER EVER make use of the protection circuits of chinese power supplies. In theory it should work - yes, but practice is another thing. Please make sure to always use a power supply, that is not overloaded. Load next to full (80-100%) load is ok, especially because switching mode power supplies have their highest efficiency in the range from 50-90%, but never use more than 100%. You never know, if the amperage regulation works as it should, producing a "clear" lower voltage in consequence. Sometimes the output voltage got high ripples on it or the power supply can withstand overload conditions only for a couple of time and then go to hell and fries your lovely Touchpad!
Please don't do that to this wonderful Tablet. If you want to, build your own power supply/charging unit like me or at least buy a quality made one like the original HP charger which is definitively capable of delivering 5,0 - 5,2 volt @ 2A or more.
