GCZ 3000A Peak Portable Jump Starter with Air Compressor 150PSI, Battery Booster for All Gas & 6.5L Diesel Engine, 20000mAh Power pack with Dual Cylinder & LED Display & Flashlight

I received this jump starter/inflator/powerbank combo and have to say I like it. It is a well designed and laid out device that is easy to use. Inflator works great for pumping up balls and bike tires. I've not tried it yet on a car tire but imagine it will work similarly. The jump starter feature seems easy to use. I practiced using in for when I will actually need it in the future. Easy to put together and operate. I also tried the powerbank capabilities and recharged my cellphone a couple of times off of it.

Very convenient, small, compact, a necessary thing in any situation - at least the car stalled, at least the wheel went down! I recommend it, as it is a very necessary thing! The seller did everything quickly and qualitatively! I recommend!

purchased this pump the other day after reading about the specs online. we took it on a roadtrip to be used for our minivan and for the 3 bikes we were taking with us. It's a great little pump and the build quality is nice

Absolutely love this. Easy to use and all functions work as expected. This is going to be very handy.

I love this thing it blew up 4 tires from 8 psi to 35 psi. still had power left. plus it has a battery jump start havent tried it yet but I will. Charged it after pumping up the tires and it didn't take a real long time couple hours maybe pretty good I though.

I had bought one of these last year and it didn't last but about 2 months, so I tried reviewing these. And I found this one, and it seems to have been very reliable. It starts my car, not a problem. It airs up all the tires of my car within 2 minutes per tire. They were all aired up at appropriate psi, so 2 thumbs up my in opinion.

All 3 units are not holding the charge. I have to charge it and use it at the same time. If I try using it the next day it's dead.
