Reliable and easy to use
on July 16, 2026

[This review was collected as part of a promotion.] I've been using this Stanley Fatmax jump starter for a little while now and so far, I'm happy with it. It feels solid and well made and the handle makes it easy to carry around. The built-in air compressor is very useful for filling up air in the tires and the USB ports aee handy for charging my phone in emergency. The display is simple to use and everything is easy to understand. I also like the fact that it has a built-in LED light which can be very helpful at night.

Everyday portable battery!

[This review was collected as part of a promotion.] Multi functional portable battery. I have been using this for numerous occasions aside from jump starting a car. Charging phone, charging lights or emergency energy. The combination of this Stanley setup is perfect for all occasions. With the weight I would suspect this is super safe around kids.

Awesome All-In-One
on June 20, 2026
Posted by: JanelleS
[This review was collected as part of a promotion.] We have a car that’s been sitting untouched in our driveway for over 2 years, so I figured the battery was basically a lost cause. I hooked up the Stanley FATMAX 1500A jump starter, clamped on, and within seconds the voltage display jumped from flat 12.8V to 14.6V and the car actually started. I was genuinely shocked it worked that fast on a battery that had been dead for that long.
What I loved:
-Power on demand: 1500 amps was more than enough for a battery that had been neglected for two years
-Power on demand: 1500 amps was more than enough for a battery that had been neglected for two years
-Real time voltage readout: the digital screen made it easy to see exactly what was happening - watching the number climb as it charged.
-Built in air compressor: the 120 PSI compressor and hose tucked into the unit means I don’t need a separate tire inflator in the garage anymore
-Bonus features; built in LED work light and USB ports (including a 25W PD port) make this useful for way more than just jump starts
-Sturdy clamps: the clamps felt heavy-duty and gripped the terminals securely, even with some corrosion on our old battery.
It’s a little heavy but that’s to be expected for a powerful compressor, light, and jump starter all in one.
If you have a car that’s sits for long stretches, love camping, or are just looking for an all in one tool, this is a great investment. I highly recommend!

Great 2 in 1

[This review was collected as part of a promotion.] Fantastic two in 1! Light weight for being a compressor and jump starter makes it easy to switch from one need to the next. I like that everything has its spot and wraps up neatly. Also appreciate the on off switch on the side to the jumper cables. Easy to read screen that tells you everything you need to know from battery life to psi. Convenient flash light and USB charging ports. Has plenty of power and battery life. Do wish the cables were a little bit longer.

Must-have for road trips
on June 18, 2026
Posted by: EduardoH
[This review was collected as part of a promotion.] This is a lifesaver multi-tool, definitely a must-have for people that spend a lot of time driving or enjoy road trips. It is a little heavy but the handle makes it easy to carry. Love that can fix both drained batteries and tires alike. Super convenient and doesn't take much space.

Multiple Uses in One Tool
on June 18, 2026
Posted by: AngelicaH
[This review was collected as part of a promotion.] This is a wonderful compact tool to keep in your car, your camper, or anywhere on the go! It has plenty of battery life. I can use it for multiple things, from airing up tires, jump starting my truck, airing up sports balls, charging my phone and so much more. It has a lot of benefits making it perfect to always have on hand when you're in the go.

Very useful
on June 17, 2026

[This review was collected as part of a promotion.] I really like this Stanley jump starter and air compressor. I will say it’s a bit heavy so it could be a little hard to use for some people. It’s also a decent size but I always think it’s good to have a jump starter in your car and it will easily fit in your trunk. I really do like that it also works as an air compressor making it so you don’t need to also carry that.

Great multi-functional tool!

[This review was collected as part of a promotion.] I love the multi-functionality of this! It can help air up tires, charge your battery, and is a power source for things like charging your phone, lights, etc. My husband used it for our farm truck, and it worked great! I plan to keep it in my vehicle for emergencies.
