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.

Amazing Product

[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.
