Amazing!

This thing is amazing! Eventually got a second one for the father in law because this works so great! We have a 6.4L diesel, and this fires it right up from complete deadness! Even handles ask our tractors. Lasts for several charges/uses before having to re-charge. I definitely recommend this product! Read more

Look elsewhere unless you want a single use product

When I first got it I charged it up and was able to use to jump start a vehicle. No issues. Some time went by and needed to jump another vehicle. No charge so I recharged it overnight. Zero power. Tried recharging it again and zero power. A AAA membership is less than the cost of buying this product and only getting a single use out of it. Read more

Quality jumpstarter

Started up my FJ cruiser that has been sitting for a couple years. Battery was completely shot but that was not an issue for this bad boy. I do wish the cables were a bit longer though as more hybrid vehicles are on the road. I tried to jump one today but my cables weren't long enough. Other than that, great quality product! Read more

Great jump starter!

This is a great design and there are a lot of nice features. The clamps are more pointed than most so they are easier to get into tight areas. There is a voltage read out on the battery cables so you can test the voltage without using the jump pack. I’ve used it a few times and it worked great. It will boost quite a few vehicles before needing charged. The only con was that it says 8000a in the listing but the one I received said 6000a on the box. I would still definitely buy it again.
