This got me through a dead battery enough to get to the auto store, so it looks like it works! Easy to use, just clip on the clamps and start your car. Takes a while to charge, but the number of jump starts you get out of it is well worth the time. The price was right, so I can't complain. The flashlight feature isn't something I really want to use all that often, but it's nice to know that it's there. Small enough to remain in the car even when you're not using it.

Great , very handy , works great. No need for extra vehicle, or battery.

Started my duramax from dead. It was only good for one jump but it worked and that’s what I hoped for. It does take a while to charge hence the 4 star review

Works really good for being so small. Great product for the price. Jumped my car when the battery was completely dead and the jump pack was only at 40%. Really glad I bought it. Also has a flashlight and you can charge stuff like your phone. Comes in nice travel case also. Had two of my tenants buy one after I let them use it. Both me and my tenants were surprised on how well it worked. One tenant got the next size up.

I've used this to jump my neighbors car 3 times and it's still used about 10% each jump.This is quick and easy to use on all car batteries that I've seen even in the older 60 models that collectors fix up. It jumped a64 Galaxie vonvertible just as well as it did a 2017 Mazda. SUPER HANDY to have in your car.
