Did not work for me.
I either received a non functioning power pack or the pack itself is not strong enough amperage (800 amps) to start car battery. I have requested a refund and bought a competitors power pack (1,000 amps) that has worked every time I have used it. So not sure this pack is more of a phone charger type than anything else. On the plus side it appears to be well designed and I like the compact size of it but that’s about as far as it goes, unfortunately.

Great to keep in car or truck
This is an excellent device to keep in a car or truck. It will easily jump start a dead battery. It is very small and convenient. It is used by some law enforcement agencies. Works great.

Jumps better than the big ones
I’m not sure how something’s so small can work so well, but this unit will jump start a car battery better than the portable one. I used to lug around that is the size of a car battery. It does not take long to charge it and it holds a charge for a long time.

Leeds don’t come out of main unit. Additional connection not shown.
Looks like a quality product however the picture is deceiving. The leads don’t just connect to the main unit. There is an additional box the leads are connected to that connects to the main unit. Makes the product not as portable as shown in the picture.

Can be used to start predator generators with electric start
I need to start my HB generator about once or twice a year. I start it a couple of times during the year for maintenance and only use ethanol free gas. Rather than worry about the battery, I’ve wired a compatible connector (available on Amazon) so I can jump start it with this unit. It works great!

Great product. Highly recommend
Bought to carry in my saddlebags. Used it to jump a jeep and a diesel truck. Worked great and very affordable. Easy to use. The battery holds a good charge, and was still at 75% after starting 2 full sized v8 vehicles
