Part of my pre-flight check the night prior to a gig is to make sure the battery is topped off, and then attaching it briefly to the deck and make sure everything looks kosher.
When I arrived to the show the next evening I realized I had left the power bank plugged in to the deck overnight and the battery had lost 3 or 4 (maybe 5? my old man eyes are dog shit) segments. I run an L-series battery as redundancy, so no biggie, still had at least enough juice for 3-5 hours before the L-series would ever have kicked in.
It's an Anker power bank and only about 3 months old, so I kinda think it's not the battery going south already. I also ran a run-time test once I fully recharged and got the expected results.
So what may have happened, other than me having a senior moment by not disconnecting the USB-C cable overnight?
Additionally, I only remove the L-series battery every 3rd month or so to throw it on a charger and have never noticed much of a dip in amount of charge available, if at all, so to me it seems isolated to powering via USB.
Not a big deal other than remembering to disconnect the power bank from the deck when not in use.
Has anyone else observed this? Maybe the TC gen, clock, and/or BT draws power over USB even when powered off? I know the TC gen only maintains itself for about 4 hours after powered off according to something I read from SD.
In any case, something to be mindful of.
