On Oct. 2, I purchased from Sam's Club a newer model Stanley FATMAX 450 Amps for $59.98 (+tax). Regrettable, I'll have to return it. The recommendation is to charge it for 40 hours prior to first using it. I hooked it up to 110 volts on 10/02 at 5:00 PM and today is 10/05 7:45 PM. The unit has still not been charged to where the green light comes on during a battery test. I attempted to jumpstart a riding lawn mower yesterday late afternoon, but it did not work. Have no problem jumpstarting the mower from my car battery.

My Car Was Parked In The Garage, Engine First. This Came To My Rescue. Also Use It At The Soccer Ball Field To Air Balls.

I use this to power a wireless camera, it works really well.

This item is so handy to own I am so glad I bought.

Many uses is ideal. Small enough for storage in cabinet.

Just the right tool with right connections, excellent product. Would recommend it for the handy man

Nice unit, but in this model 450 amp Stanley the LED lamp does not rotate.

Great item just in case something bad happens. Pays for itself after one use.

I received this product a couple of days before I left on a camping trip with my niece. On the last day we discovered the passenger front tire of the motor home was very low. I set up the compressor and in no time the tire was inflated and ready to go. The instructions were clear and the product was very easy to use. It's not heavy either.

Unfortunately, the internal batteries do not hold up for very long. I pulled mine out, not to jump start my truck, but to put air in a tire while up north on vacation. First I found that even though the charge indicator said I had a full charge, the pump only ran for about 15 seconds then slowed to a crawl. I figured that the batteries were bad, but all was not lost because I could run an extension cord to the unit and run the compressor off the AC circuit. Wrong! The AC circuit has a very weak transformer so it was useless when trying to use it to give me enough power to pump up a truck tire.
