How much current can you draw from this case? Some of them are set to only 0.5 Ampers. Also is there some kind of undercurrent protection? (Some of them has auto-shutdown when there's low current draw. It is not suitable for powerinv low power devices like Arduino Nano). But anyway - good job!

Hello, the box has 2 output that can drag 1A or 2A ! But I did not check the values, they may be overestimated :) About undercurrent protection, I dont know :-/ Thank you very much and sorry for my bad English ^^
