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

This NEXPOW jump starter has been a lifesaver! Living in Colorado, I've had to deal with my car battery dying during harsh winter mornings after heavy snowfall, and this device came to the rescue 2-3 times last winter. The 4000A power was more than enough to get my car started immediately without needing to call for help.What I love most about this unit is how compact it is - takes up very little space in my car but packs so much functionality. The battery holds its charge incredibly well, even after sitting unused for weeks. I've also used it as a power bank on long road trips to keep my phone charged, which has been super convenient.The built-in flashlight is surprisingly powerful and has been great during nighttime emergencies. But honestly, the tire inflator feature might be my favorite part. Being able to check and adjust tire pressure before long trips. The 150PSI capacity and digital display make it easy to get the exact pressure I need.The design is really well thought out - everything feels sturdy but portable, and it's incredibly user-friendly with minimal setup required. The LCD display is clear and easy to read. Having PD60W quick charging is just icing on the cake.This is definitely one of those products that you hope you'll never need, but when you do, you're incredibly grateful to have it. Highly recommend for anyone who wants peace of mind on the road! Best value for money!!

We use this thing every week.I fill car tires, lawn mower tires, wheel barrow tires, jump start cars, jump start the lawn mower, etc. I has gotten us out of some dead battery scrapes.In 4 months time I've probably used it 15 times.Has no problem turning over my Ford F250 V10 and I can get 10 or more cranks before the battery drops too low.

Very good product only reason for a 4 star is the pump pressure gauge not accurate at all if you are holding the unit in your hands as you may need to do in many occasions so you must have a separate pressure gauge to check.My has been off as much as 4 psi.Other than that the unit and the case it comes in are both very well build.

Everyone should have a battery jump starter in their car. This one works well and the air pump is slower than if you went to a gas station but it gets the job done. Charges up quick if you have a fast charger and it’s on the small side for one of these air pump jump starter combos.

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.

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
