Car Jump Starter with Air Compressor, 150PSI 7000A Peak 24000mah (Up to All Gas or 8.0L Diesel Engine, 50 Times) Portable Jump Starter 12V Auto Battery Jump Pack QC 3.0 with 160W DC Out

I bought this for my nephew with an older car. He travels far to work and so does my niece. I explained him how to maintain the car.But driving a 2009 car with 120k is still a risk. Last weekend he got stuck, car did not start. Luckily he had the jumpstarter with him, it worked great, was easy to use and got him back on his way. The capability of the jumpstart seems very good and he only needed one try to turn the engine over.Today, we checked out the battery level was almost full. Charging is also very easy from your home outlet. Further, it's compact and easy to store, and you can use it for camping or during a power outage. Great investment!

I just purchased this system. After initial charging I used it to top off car and motorcycle tires that were each a bit low. Worked great -- easy to set up. The pressure gauge matched my own, and the unit shut off when it reached the desired level. The unit came packaged very well -- no scuffs or scrapes. I like the carrying case as well. A USB charging cable is provided but not the charger itself, so I used my phone's charger (with the unit's provided cable). I think that's fine, but I would prefer it to be provided in lieu of the cigarette lighter adapter. The light is very powerful. I am happy with the purchase so far. I only rated it 4 stars due to no charger adapter, plus I have not used the jump starter feature, nor can I comment on battery longevity as of yet. I will update my review once I have more real-life experience with either. I do recommend this based upon my experiences so far. [Updated review] Updating to five stars. Due to a rapidly deteriorating battery on my Mazda I had to jump it multiple times until I was able to get a replacement. The unit worked great. I am happy with my purchase and have recommended to others. Fingers crossed on longevity :-)

After researching several devices and owning a different device, the BRPOM unit was chosen and I'm extremely happy with it so far. Used it once for a jump start and filled several tire and it worked flawlessly. Instructions were clear and easy to follow. Especially liked the ability to preset the chosen tire pressure which automatically stops when reached. All units seem to have the same complaint about battery clamp leads being too short, but these units are compact and easy to set down close to the battery. Highly recommend the BPROM model.

My first experience was great, this product did everything it said it should , worked for about 4 months, then the unit itself would only charge up to 2 bars, 4 is full. It still worked, but it was annoying. I tried to contact customer service, but being mfg. in China lent itself to some challenges. That all being said, they sent me another unit, no charge, works great, and I am fully satisfied, the only reason I would not give it a 5 way due to the original problem. It is a great unit, compact, well made, easy to use.

So far so good! I can tell you I’ve felt more secure driving around now that I’ve got one of these. Battery starter and tire inflator functions are good, solid performance so far with use. I use it every few days to check and adjust my tire pressure, with the wonky weather we’re having, and it’s pretty fast and accurate. Two thumbs up.

Works great. Easy to understand.

ORIGINAL:I haven’t used it yet, and hope I will never need to. But just having this in my trunk makes me feel better. I read the How-to, it’s pretty much self-explanatory but it’s nice to have that in the box as a reference. The box it comes in is solid and contains everything you need, and it is actually pretty small in my trunk.I found it loads very quickly, but then it was already over half loaded when I got it. I check the charge every so often, it holds on like you wouldn’t believe, I don’t think I’ll even check again for another 3 months.UPDATENow I would like to give at best minus 5 stars.The dreaded situation happened - my car doesn’t start when I leave the office, I can’t even open the door. Thank god I have an oldfashioned key. The battery is clearly dead a a dodo.No worries, that’s what I bought the battery jumper for, right? No.I take the jump starter out of its storage box, check and it is fully charged. Connect it to my battery and try to start the car. Nothing is happening. Not even the weird „ououou“ sound that you sometimes get when the car won’t start.I leave it connected for 5 minutes, perhaps that will help. It doesn’t.Now I read the little manual several times, perhaps I made a mistake? I didn’t, I did exactly what the manual said.At this point I begin repeating the same procedure that didn’t work the first time, praying for a different outcome. Of course the outcome didn’t change.Two colleagues come by and try to help, they read the manual and do the same thing I did, with the same result. Obviously engineers don’t necessarily know cars any better than I do.After trying uselessly for another 30 minutes I call AAA. Wait time 2 hours.I finally get home at 6:30 pm with smoke coming out of my ears.Over the weekend I ask a neighbor who knows cars if he could take a look. He checks the jumper box for voltage?/amperage? with a little tool and says that it has juice. He doesn’t know why it doesn’t work.I bought this bloody car jumper for one thing only, to make sure I don’t end up stranded somewhere.It failed miserably.I have no idea how to check if an electric/electronic item I buy works, I have to rely on internal quality control of the company.This one was a resounding failure, and of course I only found out many month after I bought it.I am just happy I wasn‘t stranded somewhere unfamiliar after night fall.Avoid this crap if you can. I bought long jumper cables - it’s never a problem to find someone to jump your car, but many people have no cables in their Trunk, or too short ones.This was not cheap , and it was a complete waste of money.

not the cheapest but works great, both as a battery starter and a tire inflator. The battery seems to last a long time (several months) without needing to recharge.
