i want to bring the largest possible power bank I can onboard to charge my devices. I believe I'm limited to 100 Wh or less and that it. There's no output voltage maximum or mAh maximum? Power banks normally use lithium ion cells which are 3.u volts but use a boost converter to get it up to 5 volts. So largest lithium ion power bank I can bring on board is (100 Wh)/(3.7 V) = 27027.027 mAh? Can someone please confirm? I have a 26800 mAh power bank that uses 3.7 volt lithium ion cells that has 99.68 Wh written on bottom of power bank that uses 3.7 volts in the calculation and not the 5 volts it outputs because the cells are 3.7 volts. Can u please confirm I can bring this power bank onboard?
