Booster Battery Pack - Charge using my car?

General Discussion
#1

Have a booster battery that gets plugged into the wall to charge. Can I keep it connected to my car battery to charge it, instead of the wall? Just a curious question.

Thanks!

The better ones use Li Ion batteries that require a special charging protocol, so in those cases no.

If it uses a 12 volt lead-acid battery, perhaps yes, but check the documentation. It could wind up being overcharged in some cases.

For what it’s worth, I have a Duracell Powerpack whose manual says that it can be left on the AC (home) charger at all times but that it should be removed from the DC (car) charger when charging is complete.

thanks for the feedback. I’m just curious - I will definitely check the documentation. Not sure if it’s lead-acid or Ion batteries. Great day all!
