I use this one, in my Milwaukee dial zone jacket, it runs on high on both zones for about 5 hours.

Has anyone noticed their battery draining 24/7 when plugged in? I’m not sure if it’s the battery, I have a defective unit or this is normal…

make sure your battery is QC3.0 POWER BANK. SOME POWER BANK WITHOUT QC3.0 FUNCTION but mraked QC3.0 . So you need verify that.
