NEXPOW 3500A Car Jump Starter with Air Compressor, 12V Portable Battery Booster (9.0 Gas/8.0L Diesel) with Emengency LED Light, 150PSI Air Pump for Cars

All around great but. The unit is perfect size ,light weight simple to use I used it to jump friends diesel truck and it did exactly that no hesitation whatsoever and on the first attempt started right up. The price great buy win win all the way around, have never had any issues with jumper. Highly recommend my û

I am surprised by how good this product tirelessly works. The seller shipped it very promptly. I use this unit very often and it never failed me. You can inflate an empty tire 0 tp 36 PSI just in 10 tp 15 minutes depending on your tire size. Just jack up the tire until no contact on the ground if it is empty. Otherwise it won't inflate. I use it to inflate my ebike too. The PSI set works perfectly and stops inflating at set PSI so that you won't need to worry about over-inflating. You can charge the unit in your car as you go so that you can keep it in your car al the time. Just avoid the unit from prolonged direct sunlight contact as you would do with any battery. The jumpstarter also crank most dead batterirs in an instant! It has a very super-bright LED light too! I highly recommend getting one. It is a steal for the price!

I bought this car jump starter with compressor for a friend's birthday. We have one and it is a valuable tool to have. If you are out and your car is not starting or you need to put more air in a tire you will have all the help you need. It is the best thing I've ever bought for emergencies.

I needed air in a tire, I bought this item and it turned out better performing than what I expected. I recommend this item for several reasons. Good quality and good performance.

works great for jump starting a light duty truck. haven't used the tire inflation yet but it sounds like it's powerful to inflate enough to get by in an emergency.

I'm genuinely impressed with the NEXPOW 3500A Car Jump Starter with Air Compressor. For the price, this thing delivers serious value. The power level is no joke—it fired up my vehicle without hesitation, and knowing it can handle larger gas and diesel engines gives real peace of mind. Ease of use is another strong point. The instructions are clear, the clamps are straightforward, and everything feels intuitive, even if you're not mechanically inclined. No fumbling, no guesswork—plug it in and go. Battery life has been excellent so far. After multiple uses, including jump-starts and airing up tires, it still held a solid charge. The built-in air compressor is a huge bonus and saves time compared to digging out a separate pump. Bottom line: this is a dependable, well-built tool that earns its keep. It's one of those purchases you hope you won't need often—but you're really glad you have when you do. Highly recommended for anyone who wants reliability without overpaying.

Due to the cold weather both my car and pickup needed more air in their tires when this arrived. I was able to easily air up all 8 tires in a matter of minutes! Now that I know how well this one works I am purchasing another so we will have one in each vehicle. The usb port was a comfort when there was a threat of losing power during the recent winter blast, knowing we would have charged phones and tablets through any power outage.

I already had the occasion to use the Nexpow. Loved how easy it was to set up. How easy it was to use. How compact it is and how powerfull it is. Jump started my dead battery in seconds. The instructions were clear and concise. The terminal connectors were simple to attach. all around I gave it a 10 out of 10. The last comment. It's beatifully designed.

First off, item came quickly, seemed good, this is nothing to do with the seller really, and as of today, I have not tried to contact them about this "issue"... But after reviewing the listing again there is nothing to say about warranty, and like so many things I buy online, it may be weeks, even months, before I use it, and by that time, refund and warranty windows are closed. That said, after "kind of" using this maybe twice, which it barely did "what it is supposed to do, in that, maybe it actually jumped one of the two vehicles, but it at least appeared to "try". As of yesterday, the third time to "NEED" it, it did nothing. I then spent the next 1.5 hours "fiddling" with this mickey mouse jump box, BTW with 4" leads(super awesome to have to keep the jump box within 2.5" of the battery, upside down!), and it did not even seem to try to help, or start, anything, and that was just my motorcycle, much less an actual 8l diesel engine.. Yeah right.. Basically, complete garbage and a waste of $45 I could have put towards something that at least worked for one season.. No pics needed.. It looks exactly like it does in the ad listing.

company has terrivle customer service. my item was lost, reached out then followed instructions to reach out to fedex. fedex needed more info from the company and after about a week of a couple emails still no response from company. wouldnt recommend this seller
