It holds a charge for a long time. I leave mine in the car and every time I've checked one of these jump packs, it still indicates full. I usually plug them in once a year.
@@thegearbunker9842 thanks for the reply - definitely gonna get one! FYI - I just got the Shell SBC 400 4A smart charger. My F150 battery has weakened because I don't drive much. Tested at 360 CCA out of 760 and below half charge. Plugged the charger in over night last night - tested again - reports fully charged and 785 CCA. Just need to see how long it stays that way. Great little charger for $55 from Costco!
Can I charge the jump starter by connecting the USB end of the cable provided to a USB port on my computer? Also, can I connect the USB end of the cable provided to any certified USB (AC) power adapter?
This really would have come in handy this week. Thank you for reviewing this gem for me.
Sure thing
Thanks! Your review helped a lot.
Glad it was helpful!
What's the boost button do on the cables?
I bought one but unable to get 'on-board power supply 12 volts maintain' for the vehicle while changing battery. Please advise, thank you.
Nice review - thanks! I can get this at Costco in Canada - How long does it hold a charge if not being used? Should it be continuously charged?

Yes
Surplus stores are selling these. I’m debating on buying one or a more expensive brand .
Can't hurt to have one in each vehicle
Can this be left in the car during the harshly cold winter?
Yep
