15W PD limit?

[frtodd]

The quick start guide for the PineTab2 mentions only charging at 5v and 3 amps. I.e. not using a charger beyond 15W. 

I took note of that, too. What it actually says:

The PineTab2 should be charged using a 15W (5V 3A) USB-PD power adapter. Charging at a higher voltage may result in damage to your device.

My interpretation:

You need 15 WATTS minimum to properly charge the device. That's reasonable. That's the power capacity of the charger.

Charging at higher VOLTAGE will damage it: 5V (the USB standard) is what's required.

I plugged it into my laptop dock with 85W PD: it works great. I left it on an Anker charging station overnight: that seemed fine, too. Some of the more puny device chargers you may have lying around may not produce enough power, though they will still be operating at the USB standard of 5V. Upping the voltage with some other random charger, though, would not be helpful.
