⭐⭐⭐⭐⭐ This compact device is very practical and convenient to keep in the car. I used it to jump-start my car, and it started immediately without any problems. The clamps feel sturdy, and the instructions are easy to understand. The air compressor is a great added feature. The digital display is clear and easy to read, and I like the function that allows you to set the tire pressure and have it automatically shut off. It's not very noisy, and the inflation speed is quite fast for a portable device. The build quality feels excellent, not cheap at all. The LED light is useful at night, and all the accessories store away nicely. Overall, it's great value for money and gives me peace of mind when driving. Read more

Works great. Do not have to call road service for this particular problem. Read more
I have had the jump starter air compressor for about a month. Having a parasitic battery drain, the battery has gone dead 3 times. Each time following the manuals skimpy instructions the unit failed to provide current to start the engine. In fact, nothing happened at all. The units battery charge show a full charge yet it has no effect for starting on my F150 V6 ecoboost. I had no need to try the tire pressure system and have no comment on it. I am past any return date having waited, as I had hoped it would finally prove itself. If things change or the company contacts me with a solution to this problem, I am more that happy to consider revising this very negative review. The company contacted my thru Amazon email and offered a refund and expressed their concerns with my product issues. They did so in response to my review. Clearly my issue may likely be a fluke or something associated with the circuitry etc. in the newer 2017 F150, I just don't know. However, a company that is that responsive and kind must make and sell very good products. I just got a short stick, so to speak. That happens in life and one adjusts. Thank you to the KOLTGOO company. Read more

Don't buy it. I charged up this device. I attempted to use the air compressor function. The air compressor worked and I added some air to a car tire, but it would not shut the compressor off when the desired pressure was achieved, even after carefully reading instructions, I was not able to shut it off at all. It was pretty loud and I eventually had to put it outside, where it continued to run for an additional 45 minutes. No customer support phone number. After the device ran out of charge, I attempted to recharge it but the device was unable to charge up Read more
Quality product, form-fit-function, value, battery life & charge capacity all worth it. Air compressor worked up to 100, didn't try higher. Must have for RV trips as stress relief. Read more
