and do not think it is 100 amps for more than a few seconds. alternator works great. helped determine need for new battery

This is the 3rd FatMax I have purchased from Sam’s. Great rescue device (jump and inflator) that fits neatly in a trunk.

Seems like a nice product. Fortunately I haven't had to use it yet. Charged it up, tried out the features and secured it in my vehicle.

I disliked the anticipation on being able to contain myself while the product was in transit, and was eagerly looking forward to its arrival!

Compressor works great. Setting the pressure and not having to watch or keep checking pressure is nice.

came DOA been trying to charge battery, wont hold a charge, works plugged in but when I unplugg it screen is blank.

Excellent tool for car support. Battery jump box with an alternator checker, tire pump, cell phone charger. Also easy to recharge.

Thankfully, I've not had a need to use this yet. But it gives me a sense of security knowing its there when (not if) I'll need it.

Worked for a few times but now the air compressor shorts out as soon as you try to use it. Not so good

I bought this unit because of the multiple features. We will take it with us on road trips and also with us when Side xSiding.
