Perfect compact jumper!
Perfect to keep in your car! This is a durable battery jumper that takes up little to no space. During the winter, I’m always afraid of my battery going out on me. This is easy to use and has great power capacity to ease my nerves as the cool temps hit. I’ve only used once so far, but it was quick and seamless to connect and get my car jumped!

Must have item!
[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.

A powerful, well built, and easy to use jump start
[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.

Compact and powerful
[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!

Good jump starter
[This review was collected as part of a promotion.] At first I didn't expect this small tool could really help me with my vehicle problem, but it did it clamps really well the indicators tell you everything you need to know. I liked I could charge it for on the road and it has a light and a carrying case for traveling.

Handy backup for the car and road trips
[This review was collected as part of a promotion.] Used the Stanley FATMAX LJ18FC a couple of times — works just fine. It’s compact, easy to keep in the trunk, and has enough power to jump a regular car without issues. The USB-C port is great for charging a phone or laptop on the road, and the built-in light actually came in handy once at night. Not something I use often, but it’s good peace of mind to have for emergencies or camping

Versatile Charger!
[This review was collected as part of a promotion.] We had our first cold weather of the year, which usually means either a low battery or low tire pressure. This time it was the battery, and honestly, I’m glad because it gave me the chance to really test out this charger. It works quickly, has a built-in flashlight, and even includes ports for charging other devices. Everything stores neatly in its case and is easy to set up and use. I’d absolutely recommend this as a gift.

Fast charge
[This review was collected as part of a promotion.] What a great Stanley Fatmax to have handy while in commute anywhere, as i'm a single female, usually driving alone. With the added features of the 4,6 and 8 cylinder engine. Feeling safe, on the road with the added capacity and reliability of the Stanley 1800A jumper cables. Very good product with a trusted brand!!

Definitely a must-have for every car owner
[This review was collected as part of a promotion.] I highly recommend this product! We actually had a car — an Infiniti — that had been sitting for two months and wouldn’t start. But the STANLEY FATMAX Jump Starter saved the day! It’s super compact and easy to carry, so it doesn’t take up much space in your car. It’s made of high-quality, durable, and safe materials, which is really important. What’s even better is that it also works as a power bank, so you can charge your phone or other devices when you’re on the go. It charges quickly and holds the charge for a long time. We have two cars — a Dodge Ram 1500 and an Infiniti — and this jump starter works perfectly for both. It’s universal, powerful, and incredibly effective!
