DBPOWER Jump Starter 2750A Peak 76.96Wh Portable Car Jump Starter (Up to 10L Gas/8L Diesel Engine) 12V Auto Battery Booster Pack with Smart Clamp Cables, Quick Charger, LED Light Jump Box

*Edit again, about a year after initial purchase* This thing has still been a great investment. Used it a total of 5 or 6 times, and each time it has worked.Once it was on a battery that was dead enough that when I tried the DB, it couldn't quite crank, but then I removed the clamps, re-applied them, and it started right up on the second try. Basically, and so far, the thing just works.**Edit. Just used it again about two months after the initial review. Started it right up again, and that was on a little less than a full charge, maybe like 80%.***Original Review**1st, this will be in reference to a 5-cylinder Chevy Colorado, 850 CCA battery (I think). So, not the biggest, but also not a small battery by any means, in reference to the average consumer vehicle.OK, so I have previously only had the chance to use this as a portable charger. It's great for that. But that is the easy part. But......A couple of days ago I got to put it into action. My battery was totally *dead*, no lights at all, etc...It's a newer battery, so I was suspect that maybe I had an unfortunate electrical issue. So, before trying to jump it, I put a voltmeter on it. It read right around 4 point something volts. Even if you don't know anything about changing systems, that pretty much means that it's totally and completely useless as a battery at that point.Well, I hooked this little doodad up, heard a click, and put my meter back on it. It immediately read over 14v. I was actually wondering if I had read it right in the first place, maybe I didn't have a solid connection, etc... But, I looked inside and suddenly had faint lights and such. But, then they went back off. I went back out and tested again, and I was back down in the 4 something range.Now, I had read the instructions when I first got it, but didn't realize how easy this thing really was. Apparently it cuts off after a few seconds, but I unplugged the jumper cable part, plugged it back in, hooked it back up, and I was back up to over 14v. (I don't know if that was necessary, but I did that as a sort of 'reset'.)Immediately went back in the truck, turned the key, and it cranked right up! No hesitation.So, it looks like this thing is in large part fully automatic. I didn't even have to 'turn it on.' My only other experience was with using a friend's (another prominent brand that you can find on here.) And while hers' was also pretty easy to operate, there was an additional step or two, to the best of my memory.So from my experience, especially if you want this to be a gift for someone who isn't the most tech or automotive-savvy, this is the way to go. Hooking it up and turning the key was literally all it took.The only cons might be that the regular functions aren't too clear, like getting the light on and off. There's no clear 'off' switch, as far as I could tell. And, I could potentially see someone accidentally leaving it left turned on and draining it down, unknowingly. It had an auto-off feature, but not sure if that applies to the light also, and I'm probably not going to leave it to drain just to test that out.But overall, I don't think that I could be much more impressed with this little thing!

I purchased this in August 2021 and it just died in March 2025. I used it often in the 3.5yrs I had it. It always worked well and held a charge even in the cold.It just died with no warning or any signs of any issue but for the price, time I owned it, and the number of times I used it, I can't complain and will buy it again.

Happy with this purchase. My car battery was dying and before I could swap it out the car sat for 2 weeks.Upon return I could not get the car started nor would the car turn over. This jump starter worked well and was very easy to use. It has a boost setting to get a completely dead battery to come to life. I also has a light plus safety strobe and will also inflate low tires. Smaller than a shoe box and handy to have in the car for emergencies or to help others when needed. Better than Road Side Service!

UPDATE: Apparently the new one does not have the built in volt meter.I bought this in Feb 2020. It still works but the case started to pop apart. I took the case apart and the battery pack has started to swell. It always worked great and sometimes outperformed my NOCO jump starter even though it is much cheaper than the NOCO. I was a little annoyed at first for having to plug in the cables, but the built in volt meter made up for it. It's nice being able to see the battery voltage before you plug in the jumper. I did not use the light much, but did use it as a regular battery pack for charging my phone or scanner and it worked great for that too. I will probably be ordering another one even though I still have my NOCO as well.I am not sure the new ones have the volt meter, as it does not show it in the pictures, but the one I received in 2020 had it.

One of my cars has a coolant leak I’ve been unable to locate, so I took it out of service; but then it sat long enough that the factory security system drained the battery so flat that my battery tender couldn’t do anything. Right before the most recent snow storm, it was imperative that I get it started so I could move it out of harm’s way from the plow that would be coming later that night. This product fired it up straight away; but I boneheadedly had the key in the ignition and had grabbed the key set with a worn out & inoperative fob, so I had to shut the car down after getting it started in order to stop the alarm disturbing my neighbors any further. Naturally, the car hadn’t had enough time to build up a charge sufficient to restart in its own after sitting for two months. So I jump start it a 2nd time, this time with key in the driver’s door lock so I can kill the alarm once power comes up. I then have to move the cars around, and stall this one in the process of threading it into a nook in the back of the driveway, so I jump it a 3rd time, getting it into position and letting it run for a bit. I then shut it down and reconnect the battery tender only to find insufficient charge for the tender to do anything, so I jump start the car a 4th & final time, and then reconnect the battery tender while the engine is running, getting the absorption phase started, and then shutting the engine down and confirming the tender is still happy. I checked the charge on the jumper after I got back in my house and found it still showed 4 charge lights out of 4. Highly recommended!
