I started traveling and driving out of town now. Love having this in my car and know I can jump start my car or air up a low tire without anything or anyone else. Thankfully, haven't needed it for that yet. We did air up a bike tire, and it worked well and fast. The light is super bright as well!

My absolute all time favorite Product !! I have bought 10 Stanley Fat Maxes. Every family member has received one For birthday or Christmas!!! jumped started 15-25 cars with it pumped up 20-30 tires! checked 8 Alternators! Used 20+ tires for power outages Used 5 times for road side Emergencies With the Flashing Light!

I bought two of them because I was satisfied with the functionality and so far they have worked well.

Excellent device to use to jump start a weak battery engine or pump up low tires. With newer cars it can be risky to use standard jumper cables when your car has so many digital chips that can be damaged if something goes wrong.

Have already used it 3 times and works great and keeps a charge for a long time! Would recommend to anyone and will buy again when I need to a new one

Very impressed with the improvements in design of this new model.

I had the previous model. The jumpstart capability was something left to be desired (typically would only "help" if another vehicle didn't have the amps to jump another vehicle, I ran this in parallel). The compressor was great. I went to Sams, finally frustrated with the non-jumps. They let me swap for the newer (this) model. Everything is updated and better. I think the compressor could be a little better however as I was pumping a trailer tire up to 60 psi (this is rated for 120). The connector to the compressor internally broke (was still in the compressor hose, could see it was plastic). High heat, high pressure, more than likely made it give up. No worries, Sams swapped again for a new one. This one (so far) is working great. Only reason for 4 instead of 5 stars is because the internal compressor connector is plastic. I know and saw it, and it's bound to break again. Thankfully, Sams is great with returns!

So far, I haven't had to use it which is a good thing

Purchased this which I thought was new, but was actually a return to Sam's Club (seal was carefully broken and some Christmas paper on the package). Would not hold a charge, which is why it was returned the first time. Returned.

When I used this, fully charged, as an inflator to air up tires on my utility trailer, it took forever and the battery was showing on the gauge as nearly half charged after just a few minutes. I then tried it on my riding lawnmower’s tires, and again, it was slow; I managed to air up the tire on the other side as quickly using an old-fashioned bicycle pump. A shame, because if it worked well it would have been handy to have in my garage, plugged in and ready to go whenever needed.
