"I got this with a FENIX HM75R headlamp but have ended up using it as a standalone battery bank. Really handy that you can just take a bunch of extra batteries with you on a trip and swap out as you use them up. Unlike most cheap battery banks, this one is built to Fenix's usual high quality standard. It can also charge 21700 batteries when plugged in via usb-c. Note - It does get warm while charging a device."
