This is such a great buy for anyone who owns a car. To know that you can charge your own battery if it dies. That is a great feeling. The air compressor is a great thing to have in it as well. The feature of checking your alternated is a plus.

Handy little stow and go for the car, camper or just around the house! It charges up quickly, after the recommended initial 30 hour charging, and easy to operate. Happy with the purchase!

We bought one of these previously and have used it for over a year. We purchased a new one for each of our 3 sons for a Christmas gift. Every driver needs one to use in their vehicle(s).

This does what it’s supposed to do. I had to jump my my truck with a V8. No problems at all. I was able to jump my truck in 20 below 0 temperatures in less then 2 minutes. Definitely recommend.

I have used the Stanley Fatmax Pro to jump start my car and it worked perfectly. I have also used it to air up my tires. I love the auto shut off when the set inflation is reached.

Awesome device. Start your car with a dead battery, charge upto 4 USB devices, bright LED lights, and air up tires. You can set the pressure, and it will air tires to exact pressurem

Works great but looked like it may have been a return. Box flaps were ripped in several places under the tape seal. The black area around the center digital display is just a decal and was falling off.

Fabulous and compact necessity for every car. It does it all: easily charges dead car batteries, inflates your car tires to the exact pressure, inflates bike tires and basketballs, charges up your cellphone.

Great car jumper. Brought my 2011 Sonata back to life with little effort. I keep it charged and in the trunk ready to go at any time. I never have to worry about asking a stranger for a jump.

This doesn’t come with a charger. The charger must be bought separately online or at some other store in order for it to work. Very impractical and inconvenient. I returned it.
