I have 2 power banks in my helmet. One of them has lasted 7 hours, the other has gone on for 8 hours before and still had charge left. I'm not sure what the full time on it is. I do know I'm not having the fans die at a con again.I've been getting distracted by my Lady Rhea shield lately because it lights up so I just stand in the mirror for a while turning it on and off over and over lol. How long does a charge on the power banks usually last?
