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!

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.

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

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

This newer model operating position is flat. The air hose is shorter so if your valve stem is at the top you have to hold it up to get your tire aired up. It doesn't fit down in my side box like the older model I have. The light is built into the lid of the air hose cover so you can't aim it as well. It comes with a charge adapter that you have to keep somewhere. There's nowhere on the unit to store it. If you lose the cable you can't charge it and it's junk. On the older model you could plug an extension cord right into the back and charge it.

I've had this about 2 years now, and I have loved it until now, battery shows full charge, I go to pump up a tire and after 5 seconds battery is dead. Surprised, I plug it in and charge it. 45 minutes later it's charged, I hook it back up and runs 10 seconds, dead again. I test the battery and it shows 12.6V, so I guess something went wrong with the circuit board, I don't know. I searched for the circuit board and found it for about $45.00. The whole thing cost me $89.00. It should last longer than it did, I don't think it's a good value.

No power every time I needed it was dead took one back ,second one no better most likely out of warranty by now,don’t wast your money just as week as the Duracell battery I got for my tractor

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.

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.
