Haven't used it yet! Will comment after I have used it. Not happy with no home power charging 120v adapter.
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] I haven't needed to use this Stanley FATMAX jump starter to jump my car yet but it helps to know I have it if I need it. I also like how sturdy the case is and that it keeps everything together.

[This review was collected as part of a promotion.] I haven’t had to use this yet but I like that it’s compact and portable. I like that it has the bright light on it. That comes in handy if it’s ever needed early morning or late at night. The carry case is great and the indicator lights let me know everything is working.

[This review was collected as part of a promotion.] This Stanley FATMAX jump starter is a solid and dependable tool to keep on hand. The instructions are clear and easy to follow, even if you’re not very experienced with car tools. It feels well built and durable, with a sturdy design that gives confidence when using it. I like that it’s compact enough to store easily in the included carrying case, yet powerful enough to jump start a vehicle quickly. Overall, it’s reliable, portable, and great for emergencies.

[This review was collected as part of a promotion.] Absolutely love this product and the peace of mind it gives me. This photo while maybe not “inspiring” is me being able to use the product correctly after putting it together in a few minutes. I love that it has flash light too. Its in a durable case and has great instructions. Will consider buying for friends who travel , especially women. We need to be able to take care of ourselves! Stanley hit it out of the park with this compact easy to use jump starter.

⭐️⭐️⭐️⭐️⭐️ Game-Changer for Emergencies!

[This review was collected as part of a promotion.] I’ve been using the Stanley FATMAX LJ18FC 18 Peak Amp Lithium Jump Starter and I’m honestly impressed. It’s compact, easy to store in my trunk, and super easy to use—even if you’re not a “car person.” The clamps feel sturdy and safe, and the battery holds a charge really well.
I tested it during a dead battery situation and it worked immediately—no waiting, no hassle. I also love that it comes with a carrying case, which keeps everything organized and ready to go.
This is a must-have for anyone who wants peace of mind on the road. Definitely recommend!
