Can I leave my jump starter plugged into AC power indefinitely?
There was a time when this was a complicated question to answer, but it really isn’t anymore. Unless your jump starter is 10 or more years old, you can plug your Booster PAC or Jump-N-Carry into an AC outlet and leave it connected indefinitely without adverse consequences. We switched over the last of our units to fully automatic charging around ten years ago (some have had it for much longer). If in doubt about your unit’s age, the quick shorthand is that Booster PAC units have had automatic charging (almost) forever and any Jump-N-Carry with a circled BC symbol on the rear label has automatic charging.
