Great little unit just preset pressure desired.The until it hits the desired pressure and cuts off. Jump start works great. Charges up using a standard drop cord.(not included). This unit will charge a cell phone with your charging cord.

Got Covid and didn't start my truck for 6 weeks. Ordered this online, came quickly. Charged it fully like manual said, to one try to jump my truck. Great to tool to have and take portable for trips.

Great little gadget.my car went dead this weekend just had ordered this fatmax and it charged my battery less than 10sec I went from 12v to 15. I also liked the fact that I could’ve check my alternator. Definitely recommend this product

Useful, would have liked a longer inflation tubing and slightly longer negative and positive jump leads, but with the $15.00 discount I believe it is a good purchase! Thank you!

Excellent device. Holds the charge and can jump start multiple times. Note that the big red knob to turn it on has to be turned clockwise a full 45 degrees until it latches in place. When done you have to turn it back to its resting spot.

Great product! I forgot to charge my speaker but this handy dandy tool has some USB ports so we were able to enjoy our music and air up our bikes too! My daughter has used it to jump her car before buying a battery. We love it!

This works well and has plenty of USB ports, the only thing I wish it had was an actual electrical outlet/socket to directly plug in items like my old one did.

Having this in your trunk is like riding with insurance. No matter what happens....dead cell phone....dead car battery or flat tire. It's all covered!

It's ok but my other one has 1200 AMPs and has a plug. This one has 4 USB ports and no plug. It will work for what I need it to do. Will keep this one in my truck.

Good price for this product but the Stanley battery does not come with the extension cord to charge the battery. I have to return this product back to Sam's. Very disappointed about the product.
