Default battery jump pack
I have one of those battery jump packs for starting a dead car.
Is it safe to use on my Harley?

thanks

I’ve got that Noco GB40 in my bags, and one in my wife’s car.

How do you charge the NOCO Boost GB40? Does it come with a power cord or does one need to be purchased separately?

Only in an emergency. You really run the risk of expensive damage if there is a problem with the dead battery on the bike . Especially if it's down to 2 or 3 volts. Now if it's at 12.3, (which is considered dead for a starting battery) then maybe.

A dead battery really should be put on a maintenance charger and charged 24 hours and then checked.
