DCDC-USB is pretty decent power supply.
Only problem which I had found are messed timing schemes.
Ex. if i set with jumper "5sec" off delay and "never" hardoff , this is actually "1min" off delay and "17:59:59" hardoff.
I'm not sure why is that so, but other timing schemes seems to work just fine.
I need to play a little with "script" mode to make it better.
