* Very solid voltage output, seems selectable via the potentiometer from zero to Vin.
* Was able to supply >2A with very no voltage drop (two galaxy S 3's and a raspberry pi) from an old 12V wal wart
* Good build quality and easy to use/solder to
* Potentiometer soldering was a little wobbly
When connecting to a usb port, short D+ and D- together to enable AC charging - works great when charging android devices.
Planning on connecting it in my car for a higher current charger and a second to make a portable hard drive power supply
