Battery keeps failing - this is the 3rd unit since last August- it only has to run long enough to fill 4 tires then it since and is charged until the next full about say 6 weeks later - but twice now the battery failed the unit would no longer run.

I bought the unit new and it died while inflating the 2nd tire. The tires were only 35 PSI so it should have been easy. It started sputtering and grinding and no longer produced air. I took it back the next day. Would not recommend!

It's cheap enough on sales that after the first one broke after a few months, I bought another one. Poor power, air compressor breaks fast, it is really not worth even the sale price.

Tried to jump two cars and did not work, but when I hooked up regular jumper cables from from another vehicle it worked just fine. Also the USB port would shut off when only charging my phone....all the time!!!

Great unit and very adaptable. Auto shut off compressor is very accurate and fast! It is a bit on the heavy side but certainly packs some power. Worth the money...

This device is awesome. Over the past 2yrs we have bought a few for Christmas gifts. All have been used frequently (not sure if that s a good thing). Saved my daughter a few times when she needed a boost. Glad we have them.

Worked once. After the first day, even with over 70% battery remaining it wouldn’t stay on for more than a few seconds at a time. I returned it for a refund.

Not sure yet , first time I used it didn't start My truck had to call road side service and all I needed was a simple jump start which is way I purchased this, but I am going to give it another chance, and yes I did have it fully charged.

What marketing genius at Stanley made the decision to not include the power cord required to charge the unit which is required before use. Idiots! Don't buy this product.

Great! This is the perfect item to have at the time of bad weather or hurricane. It is ready to keep your phone charged. I am happy I purchased before the hurricane.
