We bought this to jump off our boats after a winter of being on dock. Worked ok. The battery life was a little short but very easy to use and the size makes it super portable

I used this to recondition a few of my older batteries. They are now holding a charge and have plenty of cranking power. Really easy to use and light weight. Small enough to transport in a vehicle or store on a shelf in garage.

This pile of crap didn't even work for five months before it stopped working. It won't charge my batteries now. It just keeps saying that dead batteries are charged when they are not. I will never buy anything off of crappy amascam again. Everything they sell is crap and falls apart and never lasts. "Planned Obsolescence is their game here. Curse them all for ripping me off like this. I paid $114.48 for this junk. Curse them all!!! They won't help me even with a warranty. It's brand new!!!!!!!!!!!!!!!!!!!!! Curse them all!!!

I have had a few charger/boost jump units. This one has no batterys to fail. It will need A/C to make it run. Its not something you would carry in your car as a jump starter. But over the years I have had those and they have a shelf life. It has a few good functions and I like the alternator check feature. Would recommend for home use. It also has a battery reconditioner that I have yet to use but down the road it seems like a good idea. Good to have in the garage and keep on the shelf for just those times.
