Heavy duty jump starter!
on October 27, 2025
Posted by: ryanh52_7298
[This review was collected as part of a promotion.] A very heavy duty jump starter and air compressor. The air compressor worked good although didn't shut off right at the pressure I set. The jump starter worked great! The only downside I see on that is the cables are very short which makes it somewhat difficult to hook up but makes cable management easy. Everything is compact and cables and air hoses are all contained. We'll see how long the battery lasts.

[This review was collected as part of a promotion.] Love this! Performance well and goes up to a v8 super convenient feels durable and is from a reputable company so you know it is safe. Love how it comes with an air compressor too so much built into such a portable machine. Strong performance and reliable.

This keeps my mind at ease on long trips and every

[This review was collected as part of a promotion.] This is what everyone needs in their car. Especially if they are someone who is a little less car savvy or drives an older vehicle. I absolutely loved how easy this was for me to use and how the instructions were so clear and helpful. I used this not only for my battery but also for my tires And it has given me so much comfort and reassurance knowing that this is in my trunk. I also really like feeling like a superhero when I pull this out for my friends or strangers who need a jump.

Portable, Durable and Reliable!!!

[This review was collected as part of a promotion.] I’ve been impressed. The Stanley FATMAX delivers on its promise of power, versatility and peace of mind with is portable build. With its 1,500 amp peak output, this unit handled a fully discharged car battery without hesitation. It doubles as a power bank: USB-C, USB-A ports, so I used it to charge my phone and tablet during a weekend trip. The solid build gives me confidence keeping it in the car for long periods. Built-in LED light and battery-level indicators make it practical during emergencies or low-light situations.

Most important tool in my garage!

[This review was collected as part of a promotion.] This works great and does everything! Starts your dead car battery instantly, pumps tires to your set PSI you desire and does it quickly. Will also charge your USB and USB-C devices. This holds are good charge for a long time. This is very well built and nothing about it feels cheap. I highly recommend this to everyone!

Very tough built

[This review was collected as part of a promotion.] This works wonderful and is amazing to keep in your car. It aired up my flat tire super fast and still had plenty of power. It's very tough with its rubberized coating. I've not tried to jump a car yet but the flashlight is super bright.

Utility necessary
on October 23, 2025
Posted by: kwamei2_3169
[This review was collected as part of a promotion.] Heavy duty box and cables. Easy to grab, easy to charge, with small sleek charging cord, and gives you instructions on how to stay safe and to not overcharge. Easy to transport, and versatile from charging your car, to pumping up the basketball in the rink. Very handy to have in the car.
