I'm looking for a pocket flashlight that can double as a power bank. My phone uses USB-C, so I'm looking for something USB-C based. Thanks to the dual direction of USB-C, this should in theory allow the power bank to just have one USB connector for power in and out. I'm not too picky about the flashlight side, though a low and high setting would be nice. Bonus points if the powerbank has an integrated USB-C cable so I can avoid having to carry one of those in my pocket too. Something with swappable 18650s would be an added bonus so I can leave a couple charged spare cells in my bag. So far in my searching I've found power bank flashlights, and USB-C power banks, but I have yet to find a combo unit.
