I'm using the same one and the run time is safe for any scenario I can imagine; if you want to put a safe number on it, just call it very comfortably 6+ hours.How long does the powerbank last?
I did something last week that I really wasn't happy with myself about that unintentionally tested it. We had a gig with three bands and we were last to play and first to sound check...I wasn't checking the times because this wasn't intended but we got there at about 11 and were supposed to be done by noon so they could spike and strike the stage, so I can say it was probably on from 11:30 or so. We went up for our changeover at 8:15 and that's when I realized that I forget to unplug from battery when we left and it had been on all day
The battery was reading 21%...and the Anagram was quite warm to the touch
So, that was ~8 hours with something left in the tank
