Did you recharge it after each use or just keep using it until it died!I looked at those but ended up going with a larger jump box. The one in the video would store easier but I wanted the larger one for my tractor as a just in case. I think it puts out 1200 cranking amps. So far I’ve used it three times this year to start my boat when we forgot to turn off the kill switch and the radio drained the battery.
