Long charge time
Works great, have used it many times to jump a pick up truck thats a '96 ford. So it can handle big batteries as well. The tire pump works well also quick and easy, the one thing I will say is if your inflating from a completely flat tire on a vehicle it will take much longer than you think. The hose for the air when filling tires also gets very hot as well, so do not wrap it up right away I recommend letting it cool off also before recharging it as well. Over all great product I bought 3 so far and recommended them to family as well none have broken yet and all of them work very well. If you want to spruce up your emergency kit this is a must have for sure. It does take a while to charge to full after use but I would do that everytime so you dont get caught needing it and the barriers dies half way through filling a tire or jumping a vehicle.

Best tool in the car
UPDATE: Still love this little unit, but my son-in-law had a completely dead battery on his work box truck and this little guy just wasn't up to the challenge. In its defense, the battery was completely dead and we only saw the little unit drop to 95% before he tried to start the truck (we got a click from the starter). Our electric battery charger took about 10-15 minutes to finally put enough charge into the battery to start the truck. So, I will keep this unit at 5 starts, but be aware that it may struggle with a super dead battery that's got a stray drawdown - probably a struggle for most chargers! Ran into the store the other day for a quick item and was shocked to come out to a dead battery after just a few minutes. Thankfully, remembered this little lifesaver and impressed quite a few shoppers as well when I didn't have to ask around for jumper cables. Back on the road in a quick minute with barely a drop in power to the unit. Also had a troublesome tire about a month ago and this little gem did ok (a little slow) at inflating my tire 10 pounds. Did use up a lot of power to take care of the problem, but still had more than half a charge. It took a few hours to charge back up and then was safely stored back in the car with the spare tire. It's been so hot this summer that I'm just a little worried about storing a battery in the car, but the car's 12v battery is always stored under the hood so I'm assuming this one is safe. I do take it out for an occasional quick recharge/refresh as per the instructions. Overall, very happy with the peace of mind this gives and hope this will last for years.

Great item for the price
Overall this is a great product, and I've already recommended it to a few friends who love it too. I can't complain about any of the features, it does exactly as described. Using the compressor drains the battery pretty quick, but with a 12v charger thats not an issue. The heat warning is great too. I filled 2 truck tires flat to full 35psi in a few minutes, and even got two of my other tires leveled (was a few psi low) before it finally turned itself off for about 10 minutes to prevent heat damage. The nozzles are good, it holds its charge for several months before discharging at all. Pretty sturdy compressor line, and the case is fantastic. Hard reinforced nylon I think? Whatever it is, its sturdy. I have two small grievances about this product. The user interface: Seriously, its not broken, you just need to read the manual to get the compressor to turn on. Two separate power buttons is a bit clunky. The LED light: Why did you put it on the bottom? If your using the compressor the light should be on the side or top so you can actually see what your doing when you set it down proper. It works great, and I've already used it a few times for other reasons. But at 2 am, helping a stranger, I want that light to direct my hand onto the nozzle for the tire and warn drivers not to run me over. Personal thoughts.

Very happy so far!
I got this in January of 2023 and wanted to give it a few months trial period to see how it held up. Love it!!! I got this mainly for the portable air compressor for slow leaking tires on my truck. Once every two to three weeks I’d have to lug out my air compressor and 50’ air hose to put about 7 lbs of air into a tire. This unit has done the job perfectly! I’ve used it to fill my tires probably 15 times so far. Is it as fast as a full size home air compressor…no. Is it about 20 times more convenient…yes! To fill one truck tire (GMC Canyon) that needs about 7lbs of air, only used about 6% of the battery capacity. I’ve actually filled two tires that were 14lbs low and was still at 64% battery life. It was very handy at the airport when my truck tire was low after sitting idle for several weeks. It has an automatic shutoff when you’ve reached the psi you set it at. It’s very easy to charge and holds a charge well so far. There is a track on the backside of the unit for the air hose that holds it snug. Comes with a handy storage case and accessories for balls and air mattresses or inflatable toys. The light works well also. Haven’t had a need to try the battery jump starter yet. It’s held up well so far and done everything I’ve wanted it to do. I don’t have to worry about getting stranded from a low battery anymore and I can bring this small pump to the low tire instead of vice versa. It is not designed to replace a full size air compressor or battery charger so keep your expectations realistic. It is meant to be used as a portable and convenient emergency backup and it does this exceptionally well.

Overall Mediocre
I can't speak for the jump starting capability as I ended up never using that part, but as an air compressor for inflating tires, it worked well enough for the few times I've used it. The screen is crap; the backlight is terrible so if there's sunlight, you need to tent shadow over the screen to be able to see it. After using it a total of maybe 3-5 times over the past 3 years, it's stopped working completely; no longer turns on and the screen just flashes when plugging it in to charge.

What i dislike on this product that you need to charge it very often , post to start one or two cars , charging time is very long which exceeds 6-8 hours to enable you to reuse .
M**.
I have started 6-7 cars in a single charge and yet it had 45% left. This is the best product you can get in the market 10/10
