This is one powerful jump box! My BMW 900cca AGM battery was killed by a bad alternator. It was down to 4.2v and had completely lost all power while driving and had to be manually shifted into neutral even just to get it on the flatbed to tow it home. I didn’t even read the instructions for this thing, just plugged in the power terminals, saw the battery was nearly fully charged, and went to see what could be done to the dead agm battery. Within seconds of connecting the positive to the jump post in the car and the negative to the ground post (which surprisingly sparked!), all the previously-totally dead interior lights powered on, the hazard lights resumed blinking as they’d been when last the car had even an iota of electricity coursing through its over-engineered system, wipers kicked back on, screen lit up and went through its check process while key light came on and the pleasant bing of a car waiting to drive happened. I was shocked. I inserted key to accessory mode, everything was good but a slight bit glitchy on the lights. I didn’t figure it would start; what are the odds a BMW requiring 900cca just to exist without any bells or whistles could go from 4.2v to 11.8 or higher, enough voltage to actually turn the engine over. And yet….I gave it a shot. Immediately the car roared to life! Astonishing! It did die relatively soon afterward, as was expected. The jump box started beeping when the voltage readout got down below I think 13.1 and I let it scream for a good long minute while I checked the battery itself with my multimeter (now at a 5.6v!) before unhooking it and saw that the jumpbox was down to one battery bar. Still very impressive. I then tried to jump the BMW with my other car, an Audi with the exact same battery. Took 2 or 3 attempts and then a long hold on the start button before the engine cranked enough to turn over. The jumpbox was more powerful right off rip (without even being pre charged!) than my 900cca AGM fully-charged battery that was running in another car! So so so pleased!

Edit: Apparently “normal” jumpboxes should not be used on AGM batteries, I read about AFTER using this jumpbox on my brand new AGM battery. When I went out to swap out the new battery from the dead BMW with the bad alternator, I noticed the battery sides were covered in a thin layer of coldish-feeling condensation. Unusual because nothing else in the car, much less the trunk or battery hole was even damp at all, it hasn’t rained, and the temps haven’t even gotten cold enough overnight for condensation to form on exterior glass, much less a plastic coated battery wall hidden in the depths of my dry, warm battery “bedroom” in the trunk. I also immediately noticed a strong and strange chemically smell I was unfamiliar with and couldn’t put my finger on it until I realized that the jumpbox had caused the brand new AGM battery to leak, just like the internet warned me about after the fact. So maybe don’t use this on AGM batteries, especially not at full power and just leave it sit there for 10 minutes. Schwoops.

Really solid and multifunctional device. Feels heavy and well-built — very reliable. You can inflate tires, jump a car battery, and even charge your phone or tablet. It also has a flashlight, which is a nice bonus. I keep it in the trunk for peace of mind — better to have it and not need it than the other way around.

This car jump starter by BRPOM has worked amazingly well! It comes with way more functions than I currently need, but I like knowing I might need them down the road. Right now, I mainly use it to inflate tires. It’s fast, powerful, and a huge upgrade from the skinny portable inflator I had before, which broke within a year. The battery life on that old one died quickly and couldn’t even handle a bicycle tire after a while.

I came across this model after watching a cost and function analysis video on YouTube (wish I remembered the channel!). This BRPOM unit was in the top 3 picks, while the others were priced over $100. For $79, this seemed like the best value, and I agree so far.

I’ve only had it for six months and used it twice, but I’m hopeful it lasts. I’d rather invest a bit more in something with a stronger motor and more features if it means I won’t have to replace it in a few years. So far, I think it’s worth it. Keep my fingers crossed it holds up long-term!

Have four of them, one for every car! I highly recommend this portable charger/ compressor/ portable light/ car jump starter.

I purchased the first one for my wife’s car due to many tire issues she was having. The compressor saved us number of tows to our local tire shop.

The jumpstart feature is very handy and I’ve used it more to help other stranded motorists then for my own vehicles. It also came in handy when changing my batter and not losing any radio presets or my specific vehicle preference settings.

My only minus would be is it is plastic. ( Understandably for this price point.) While it is fairly sturdy you can break it if dropped. The jump cables could also be a little longer for more convenience.
