Review: 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. Review: 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 👌 ## Features - POWERFUL JUMP STARTING: The S8 Ultra Jump Starter features a powerful 4000 A current and a 16000 mAh battery capacity, along with a 45 C discharge rate.
