It's amazing, jumpstarts many big engines on one go
Not only I bought one, but two of this product, and it's amazing. I bought my first one back in 2023 - 2024 and I play/deal around cars a lot, and this is one of the best products I use, it's small, and charges big engines. I tried this on Hellcats, 6.4 V8, 6.2 Supercharged V8, 5.5 V8, 5.0 Supercharged V8. I once even jumpstarted 5 different cars that were all V8 in one go, and there was still 50 - 75% battery left. Definitely recommended.

A beast of a jump starter
It effortlessly wake up my completely gone and dead AGM battery, like it's nothing! There is a boost option on the cable itself once pressed it's gonna wake up that battery no matter what, hope it continues with the same performance but so far so good 👌

Great product
This jumper starter is really handy to have. It’s strong enough to start a car without any issues, and the 24000 mAh power bank with QC3.0 keeps phones and other devices charged on the go. Easy to use and feels solid in the hand. Definitely one of those tools you don’t think about until you need it — then you’re glad it’s there.
