Great product

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

Power station review

I bought this unit for my children and my cars. I bought 4 total. All but one work properly. The jumper cables work well. The only problem I've had is when connecting the hose to inflate a tire, the unit goes dead.

The 1st time I try to use it, did not work for my V8 truck, then I tried to return it to Sam's and the gave a phone %23 I called and the warranty was still valid, and they were not able to help me. It is a waste of money and time. The worst!

Efficient

[This review was collected as part of a promotion.] Works amazingly when you need your car jumped I'm definitely keeping this in my vehicle and recommending it to friends and family because it could be a lifesaver

do not buy

my car had 4 tires about 26psi. I filled them up to 32. It took forever, and the battery was half gone. I noticed in the specifications they do not list the amp/hour of the battery. Additionally the plastic shell is very thin. Cheaply made.

Using the compressor on 4 tires will decrease the battery level of the unit. It is recommended to charge the unit after every use.

Had 2 of these that didn't work as promised. Car wouldn't start after freezing weather so I tried to start it with this. No luck. Keeping it to hopefully use to charge phones during power outages.
