I'm using the Power Boost 1000c. I read this:
"I think the only way round this is to go back to using a JFET, or by removing the 200K Enable pull-up from the PowerBoost. The JFET worked well but as soon as a charging cable touched the USB port, the power would die. I'd also rather avoid having to modify existing hardware to get this board to work."
Would removing the 200K actually work? Oh and another question: It turns out the 1000c isn't powerfull enough for my project so I might have to use a 1000 basic. Would it work with the safe shutdown? Thanks for your great work!
