I run my BBB using a 4 dollar chinese power supply 5v 1amp and works like a charm i also run my design lab and whole house from solar power and only ever have issues when the transfer switch gets switched slowly and the power does a mild brownout then the power supply/BBB needs a quick plug/unplug and all is well
