I took my Gooloo GP37+ out of the glovebox in April, charged it and put it in the drawer for next winter. I noticed that it had a 12V outlet rated at 10A that I just measured at 12.34V fully charged. I put my multimeter in AC mode, and it measured about 74 mV of ripple.
Has anyone any experience in using these car chargers as a QMX power source? Are they noisy? How many gentle discharge (let's say 1/2 discharge) cycles can you get out of one until it no longer functions as a jumpstarter?
Thanks in advance
