I bought this a couple of days ago. Followed instructions to charge for 40 hours before using. It would much easier to use and much better product if it had cables that could easily reach the battery, provide a 12V outlet to power say an automotive vacuum cleaner, and finally a power inverter to provde 110V power in times of need. For me the extremely short cables were problematic and end game.

BAD/BAD? Bought this Unit in Oct.2022 Very Slow the Charge/PSI Tire Gage Was not correct, read out/Used Tire Pump 5th time, Large Pop at 42 Pounds never to work again/ Read out for charge not working/ Metal insert Tire Connector Broken off/ I love the concept and had the 1000 Unit for several years and had no Problems at all with it. This one is Bad and can NOT use at all

After initially charging the unit for 40 hours per the manual instructions, I was eager to try this out to inflate 2 of my tires that had low pressure. The air compressor stopped working after about 10 seconds, with 5 more lbs of pressure needed to reach the setting I input. I tried it again after letting it cool down just to see if it was just a glitch or something but still didn’t work. Piece of junk, returning it to Sam’s Club today. Won’t bother exchanging it for a new one, if it happened one time and happened to others on this review board, then it’s bound to happen again.

Couldn't charge a cell phone after 9 months. Indicators show fully charged but nothing works.

Bought it, never had to use it until months after and didn't work at all when needed.

Purchased for my spouse to upgrade from one we have. This one does so much more.

battery booster side is ok. the air compressor is horribly slow

Tried to jump start 3 different vehicles with no luck. Fatmax had been charged to full each time.

My old Fatmax had an 110 AC outlet. This one does not

Great idea as a senior, for flat tire or jump stsrt
