NEXPOW AP1 Jump Starter with Air Compressor, 4000A Battery Jumper Starter Portable with 150PSI Digital Tire Inflator, 12V Jump Box (All Gas/10L Diesel Engine) with PD60W Quick Charge Port, LCD Display

It came with some charge but I topped it up. Comes with a charge cable but not a charge block. Get a 60watt AC adaptor unless you want it to take forever. (About $15 on Amazon.) Just used it to charge a neighbors sedan that wasn't completely dead (lights worked) but not enough juice to start the car. Super easy to use, light weight, started the car immediately and only used 1% of the power! Has a nice case too.

I’m very impressed with this product. It works great 😊 !!! I’ve already used it multiple times. I will recommend it to all my friends. !!

Pressure Guage not very accurate, but everything else works great. Not a big deal to use a separate pressure guage.

I got it from the Project Farm review, as a 5.7L V8 Hemi is not fun to start, and this thing apparently started an old 5.9L Cummins Diesel, which I know is harder to start. Shortly after, my battery ended up going bad, and this thing got me multiple jumps, as well as topping off my 285 70/R17 tires when they were low, either from the cold spell we have been having, or the installers failing to properly inflate them. It can do about 10PSI on one of my 33" tires (45-55 PSI) once before the internal compressor throws an "H8" alarm, which is ONLY explained on the sticker on the bottom. I checked the manual, and there is nothing. H8 means the compressor hit 185F, and needs to cool down.The compressor does take a lot more out of the system than the jumper side does, which confused me, as 2 jumps used like 4%, while the compressor in ~45F ambient took I think like 20% of charge before it thermal limited. There is a small red button on the jumper leads, but it has no function per the manual.Did confuse myself one time as I connected the leads to the battery, THEN the pack, which is wrong. the leads need to go on the pack, THEN the battery, or it doesn't work, but it actually does a better job with my RAM battery DEAD, then using my wife's RAV4 with her engine RUNNING. Like the RAV can't jump a DEAD RAM battery, but this thing can.

This device is the greatest invention for automobile owners. It can charge your battery, inflate your tires, charge your phone and even work as flashlight. I have used this 3 times since I've purchased it and it is very simple to use.

So to preface I bought this mainly for the jump starter function as I got a new full sized truck and needed a reliable tool for emergencies and this looked like a great deal, jump starter and air compressor and there are many kinds out there.. mainly got this one as it covered all gas engines and up to 10L diesel.. however it also seemed to have better tire inflator with it.. overall the tire inflator has performed at most ok .. has small meh hose that is hard to reach anything its like 20 inches maybe, you cannot swap the included hose setup out for a real air hose setup as base attachment point is garbage for this, I am not saying you cannot juryrig something but nothing will be professional and it would probably cost you a lot to get all the specific pieces not to mention the time.I tried to solve this by purchasing https://www.amazon.com/dp/B0CP395BM7?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 9.8 Ft PU Extended Tire Inflator Hose with Metal Locking Air Chuck Set also on amazon but that was a child size toy hose it does have the same base attachement though. Haven't tried to use it yet but already looking pretty grim.--->*safety* <---As an added note after running tire inflator to inflate from 30psi to 40psi on a truck about 3-5 mins this unit is super hot like you need to let it cool down about 5 minutes before you put it back or you could cause a fire and or heat damage your storage area.

So, I have a long story. I own a car that I don't drive much and the battery tends to go flat if I haven't driven it in awhile. Rather than pester my wife for a jump from her car, I thought I would get one of these. I bought my first one Dec 2023 and it worked great. I must have used it about 10 times and was completely happy. Then, this summer, it stopped working. I had been keeping it in my trunk, and since it was so hot this past summer, I figured the heat had messed up the battery. It showed 0% charge, so I wnet to charge it. The second I put it on the charger it showed 95% charge. I took it outside again to use it, and 0% charge when not on the charger. So, I figured I was at fault and ordered another one in August. Well, children, that new one failed immediately after one use the exact same way as the first. 95% charge on the charger and 0% off the charger. The second one was kept in the garage where it was significantly cooler. So I have wasted over$200 on these cruddy jump chargers. Buy anything else.TL;DR: Two of these units failed on me. The second one I bought after only one use. Don't buy. 0 Stars

small and convenient. jump-starts the car immediately when your battery is dead. flat tire - no problem, there is a pump. I recommend it. Every car owner needs it
