Perfect thing to have around the farm💯
Color: Red
This little power house is great to have in your truck, car, or around the farm. I lover that it is so simple to use, will jump everything I have running on the farm, I can almost pump any tire too w/out having to grab the air compressor.powerful battery will run the jump starter, air compresser, has connections to power phone and other devices, all in a compact design. It even has it's own light with a blue Lit gauge screen on the front. Oh yea, and the carry bag is a nice touch. Gotta give this one 👍👍 way up 💯

Easy, lots of power, incredibly handy!
Color: Red
Bought one of these for each of my teenagers. They’re very easy to use and have came in clutch many times! One charge jumped two cars, a truck, a lawn mower twice, and it’s still going. I often grab it out of their vehicle to use on the farm. These are great for cars, trucks, side by sides, four wheelers, and lawn mowers. I definitely recommend this for anyone! I wrote this review sitting stranded with a flat tire on my side by side in a Cow field, waiting for my son to bring me his compressor.

So good we bought another
Color: Red
We spend a lot of time in Baja California, and rough, unpaved roads result in lots of tire punctures. Having a decent air compressor is therefore "necessary equipment". This unit inflates tires reasonably quickly, automatically displays the pressure in the tire before you set the desired inflation pressure, and shuts off automatically when the desired pressure is reached. The display is easy to read. The short, detachable hose is easily attached and removed, and stores in the bag with the pump. The hose length works for most common automobile tires, and will work for oversize tires by rotating the wheel to bring the valve stem closer to the ground. Attachment to the valve stem is easily accomplished with its lever-lock working end. The unit can additionally function as a battery booster for starting a vehicle with a low battery. Installation of the cable for that purpose is easily done, and it worked just fine when we had to use it on one of our two vehicles one morning, allowing the car to be started quickly and easily. Charging is accomplished with a standard USB charging cable (USB-A style at one end, and USB-C style connector at the other end). We had a puncture that required the pump to be used multiple times to get the 12 miles back to a tire repair shop. We could charge the pump up easily and quite quickly via the vehicle's USB port, stopping every few miles to pump the tire back up enough to keep going on the highway without having to go through the trouble of unloading the trunk to change the tire for the "doughnut" spare at the side of the road. Having those two experiences just shortly after we received the pump was more than enough proof that we should have another for our other car. I'd recommend it for its small, easily stowable size, good battery capacity and ease of use.

It works and I’m happy!
Color: Red
This item is terrific! A bit noisy but it’s compact and works like a charm. Inflates my tire quickly. I have not used it to jump start my car, but I’m convinced it would work just fine. Great price too!

Good thing to keep in your trunk
Color: Red
This has been a pretty helpful thing to have in the car. My tires have been losing pressure recently and this helps keep them topped off while I wait to change my tires. It's easy to use and the value for the price is great. The main issue is that it seems to need a full charge in order to jump a car because I had issues using it to jump my car when half charge, but no issues at full. Also the cable lengths are a bit short.
