A life saver

[This review was collected as part of a promotion.] This Stanley jump starter is a must have in my van. I'm a single mom and I worry about getting stuck in the winter with no one to call, it's happened before but now I don't have to worry anymore. I can jump it by myself. It's so easy to use. It can be charged with a USB cable and even has a flashlight built into it. It comes with a heavy duty carrying case and is compact and barely takes up any space in my van. It's definitely worth it for the peace of mind and I would rather not have to rely on another person in these types of situations. It just makes things so much easier than the old fashion way. Works great, glad I came across it.

[This review was collected as part of a promotion.] First off I love the case and how secure and durable it feels! I couldn't have gotten this at a better time because my car did end up needing a jump start and this product worked perfectly. It help start my car the first time in my moment of need. It also works great for charging my phone as I took it on a road trip and it fully charged my phone and then some! I definitely recommend this to everyone I know!

Stanley FATMAX 1200A
on November 21, 2025
Posted by: stephtrezz118_8814
[This review was collected as part of a promotion.] The Stanley FatMax 1200A jump starter is a versatile and dependable roadside companion. With 1,200 peak amps, it has enough muscle to jump-start most 12V vehicles, including V8 engines. Its lithium-ion design keeps the unit lightweight and portable — easy to stow in your trunk or garage. One of its standout features is the built-in USB power bank, which gives you both a 15W USB-A port and a 30 W USB-C port (depending on the model), so you can charge your phone, tablet, or other devices in emergencies. Love this for emergencies! As a single woman, it’s great to keep with me in case of emergencies! This would make a great Christmas gift.

Perfect size and capacity!

[This review was collected as part of a promotion.] The Stanley FatMax 12-Amp Jump Starter is a super reliable tool to keep in your car. It has plenty of power to jump most cars and SUVs, and the built-in USB ports are great for charging your phone in a pinch. It’s easy to use, has helpful safety features like reverse-polarity protection, and feels sturdy overall. My only drawbacks are that you need to keep it charged regularly, and some people say the battery doesn’t hold a charge as well over time. But for everyday emergencies, it does exactly what it promises I have even used it to jump my wife’s 4Runner and it worked flawlessly. It’s small enough to keep in a glovebox or center console.

Everything inside of the case that they pack everything in is tough in very well so you don’t have to worry about anything being damaged. Everything fits into all specific spots very well.

Performed very well and is not noisy. I would recommend.
