Jump Starter with Air Compressor, 2800A Peak 20000mAh Portable Battery Booster (Up to 8.5L Gas,7L Diesel Engines) with 100PSI Digital Tire Inflator,12V Car Lithium Battery Jump Box Pack Power Charger

UPDATE (01/02/2023):Upgraded the product to five stars after having used its major functions. The updates are listed below:1. customer service was outstanding with a quick response to remedy the issue with the carrying case.2. The air pump continues to impress me. I used it to inflate soccer balls during a tournament weekend and two sets of JV/Varsity games on two nights. Each time it was quick and accurate. In fact, its probably overkill for this purpose but works well.Then, after returning from our trip to Rapid City, my wife's car tire was down to 20psi. I attached the pump and it inflated the tire to capacity in one try. It takes my large Schumacher at least two tries after one full cool-down in between. Additionally, I timed the inflation from 26psi to 35psi (forgot to start the stopwatch earlier) and it took 1minute 44seconds once again beating the Schumacher with ease. At less than 1/6th the size, it outperformed the Schumacher with ease.3. The jump-start. Finally had to use the jump-start feature. I drive a Chevrolet Express 2500 conversion van with a 6.0l engine and my battery drained from the cold freeze we had prior to Christmas in Rapid City. Guess it was used to the Florida weather and was shocked by the -17 degree weather and a child leaving a reading light on for two days. Figured this was a better test than using it on my wife's V6. Hooked it up and gave it a few seconds then had my wife crank the engine. I wasn't really hopeful and the Schumacher was waiting in the warmup pit. But wow, she started up and the Schumacher was sent back to the dugout. This little gem still showed a full four bars after jumping the van.The Schumacher has since been replaced in my wife's car with the Aonetogo. It charges faster and seems to last longer or just as long.Next update is at six months. If you have any questions, let me know.-----------------------------------------------------------------------------------------------------------------Not sure why my initial review and video review were not approved given they met all the required guidelines so I will make this one very brief and far less detailed.The item arrived in good condition except for a factory defect on the carrying case that was not caught by the manufacturer. Reached out to the seller and he provided a prompt reply and will be sending a new case. I will update you upon receipt.The item is constructed of 2.5mm plastic with perforations on the bottom probably for cooling and airflow to feed the air compressor. The controls and display are overly simple. Not bad, but Schumacher's control scheme is better. It came with all the accessories depicted and given I had issues with my three previous air compressor hoses dry rotting, having a replaceable compressor hose is a big plus. Otherwise, expect the quality of the accessories to be similar to what you would find at a bargain store.I've tested the air compressor on my wife's tire which was low. I decided to lower it to 10psi from normal to test the compressor's capability. I certainly was not expecting a whole lot given the small form factor but was nicely surprised. It pumped the 10psi on a 255/50ZR17 tire (low profile) in 1min 58sec and the pump was still fairly cool with a very slight warmth. The power bar still showed 4/4 bars after inflating the tire. The only drawback is the air pressure gauge was off by approximately 2-3 PSI low when measured with a tire pressure stick gauge and a digital pressure gauge. So it was approximately 6-9% off. Will see if this error works itself out over time.Hate to waste more time on this review in case Amazon decides to kick this one back as well.

Jump start works great.The compressor is surprisingly good. I wasn't expecting much with the compressor but it will air up a car tire really quickly.

Had a flat , it did its thing to give me air in my tire but it wouldn’t stop running after I was done with it. Switch doesn’t work won’t turn off and loud and annoying as hell, not worth it after two uses

Not bad for a combo jump start/air compressor.Recharges quickly.Small and convenient.Does all four tires on about a quarter charge.Jump off usually take more of a charge so it's good to have at least half.Good investment for the money.

My neighbor has a older 5000, this 4000 made his look sick , I put it on a riding lawnmower battery and right then it was turning over the starter fast to crank it

Portable and efficient, a must have.

I ordered this in December of 2022 as a gift for my son. It last 1 yr 5 Mos and jumper cables stopped working.

No complaints
