If it is 12 volt, yes.

It's possible you may have a poor connection from your car to your car battery. Check to make sure both battery terminals are on your battery tight. Tighten them if necessary, then try again. If either one was loose, that should fix the problem. Then there may be nothing wrong with your battery charger.

The charger to a Jumpstart charges at a low rate (300mA to 500mA) and will not push enough current to start a car. Best to have Jumpstarts recharged every 6 months to be ready for emergency.

If it's like mine, it probably won't charge. First time I let it run down, it was screwed, a real POS.

there are no fuses to replace(other than a reset switch on the back) if you get no responce from the unit even when you charge it then the interal circut bord is fried. it will still deliver a charge to jump start until the battery dies. after that its trash because it is not recommened to charge the intermal battery with a standard battery charger it may explode since it is a sealed lead acid battery

i have a hb-208b adapter if any one needs one

Go to this LINK and find the part/diagram that can help you.

Hi, usually after you drain the unit down it will take up to 4 hours for it to charge up 100%. but do not leave it on the charger all the time when not in use because this decreases battery life.

You should be able to try it immediately, or whenever you need to.
