  • What is the voltage at the end of that long cable under full 2 amp load? I suspect that it's low enough that some of my 5V devices won't like it.

5 Volt power adapter

This unit works very well with a BeagleBone Black.

The right angle A.C. plug is great when using it on a power strip. Takes up so much less room.

Would recommend it to others.
