DBPOWER 5000A Jump Starter, 74Wh Car Battery Jump Starter for Up to 10.0L Gas and 8.0L Diesel Engine, 12V Portable Jump Box Battery Pack with Display, LED Light, Jumper Cables, and Storage Case

Really handy and useful tool, especially if you have cars that stay parked for an extended period of time. I've jumped maybe 6 or so cars and battery was still at 70%. Love that it has a flash light and USB port to charge your devices. Just beware that using it to charge your devices does drain it pretty fast, in my experience.

Got this jump starter due to the value for the money. This says to make sure you charge it before first use. It was a 75% charge when received. Allowed it to charge up which was easy. The unit liiks like it is made well. I have it ready to use and now looking to jump off something. Grins.. It probably will be my bigger tractor with a diesel engine.

Awesome gadget! Small, powerful, effective. Great to keep in your ride!

Well, I admit I was a bit skeptical about this, having given up on lead acid jump starters long ago. But, only having one vehicle and it being a cold winter here in Maine, decided to give this a try (the nice pre-Christmas sale price helped my decision). Two weeks in, it's been used once, and saved me getting dressed and going down the stairs into the snow at night to jump-start my handyman whose car has on-going charging issues. He trooped upstairs when it was time to leave asking for a jump. I pointed him towards this, which I'd chucked into the backseat of my Jeep. The punch line is that he came back up in a few minutes declaring that he was going to buy one of these. Car started instantly and the charge is still at 100%. This device seems well made and certainly does what it purports to do. The carry case is nice and holds everything securely. It does take a while for the initial charge, IIRC correctly, it was about three hours using a 12W iPad charger. A bigger charger would likely speed this up, but according to the instructions, it only needs a top-off every three months or so which shouldn't take as long. We'll see about that. At the end of the day, I do recommend this device and I think you'll be pleased with it.

I had another brand of jump starter before this one, and it just couldn’t cut it when I really needed it. The DBPOWER 5000A jump starter has been a huge upgrade and provides the power needed for every start so far, even on larger engines. The digital display makes it easy to see the battery level and status at a glance, and the included jumper cables feel solid and secure when connected. I also like the built-in LED light, although mine no longer works, and the sturdy storage case helps keep everything organized in the trunk and ready to go. Overall, this jump starter has given me much more confidence that I can handle a dead battery on my own without needing to call for help.

Bought this for could winter nights here in Wisconsin after way to many mornings of my car not starting despite buying a battery last year with the highest cranking amps. I was not sure how well this would do as I have never used a jump box. Let me tell you this little box has saved my mornings. I haven't even had it a week and had to use it three times. I clamped the clamps on the battery, plugged it in and my car started right up. The first time I used it the battery went from 100% down to 69%. I was a little worried because you're supposed to be able to use it about 20 times before having to charge it. I brought it in and charged it back to 100% . The next time I used it it only went down to 99% so I am happy that it will at least last a few times before having to charge it. The quality of this little box really surprised me. If you are on the fence about this purchase I say do not wait. Get one now. You will not be disappointed. And what a steal for $44 instead of $129. I was so pleased I bought my daughter one so she's would never be stuck anywhere due to the cold when her and my grandbaby are out and about. It comes in a nice zipable case with a charging cord but you do need to buy a charging block. It recommends a 5.0 charging block. Some blocks are only 2. Something.

I ordered this for my elderly Dad who likes to run around driving and had battery problems at the time . Got it fixed now. But this helped him out at the time now he uses it to help others when they need a jump. He loves it. Didnt break the bank either. I personally own the same one , i purchased here on Amazon ! This was a 2nd buy of same model and brand. I carry it in my truck just in case.

UPDATE 09-Sept-2025: I still can't give more than three star on this particular model (previously 1 star), but the seller, who deals directly with the factory (I suspect they're basically the marketing for this brand in the US), deserves 5 stars. Not only did I get a refund, they sent me a free one (which charges fine and thus I bumped up the rating), and I worked with them, trying some things for them. They did reproduce the issue in their lab, and are working with the factory regarding the issue and QA. So it may be a hit-or-miss with this particular product until that's resolved, but they DEFINITLY stand behind their products. In fact, they even sent me a second unit (a different, older model that they said has been extremely reliable) as a thank you for my time. It's a different brand (S ZEVZO), but I bet it's really the same manufacture. I like that one because it shows the voltage and current it's charging at. As for my ORIGINAL review, here it is: Three strikes and they're out. I really wanted to like this product, but I can't even make myself like the brand. Allow me to explain my experience... Last Christmas I bough one of the DB Power model DJS90 jump starters (the red, 3000A unit) for my daughter since she was away at college and I wanted her to have a jump starter in an emergency. It charged up fine and seemed fine, but we had no dead battery to test it on. Now I'm concerned that if she needs it, it will fail. Why? Well, fast-forward to this summer, when I decided to buy another DJS90 for myself. It arrived NOT in its box, just it's carrying case, and it was clearly used and returned. Maybe that's the seller's fault, but I wasn't about to trust something someone else returned. Amazon shipped me another, but... Though that replacement unit was new, and shrink-wrapped, it would not charge. In fact, it made my charger, and the plug, very warm. And the level never increased. So, back it went. Now it's late August and there was a good sale on the Z07 model (yellow, 5000A). It arrived with a 75% charge, which isn't unusual because it's safer to ship Li-Ion batteries when not fully charged. So, of course I put it on a charger. (A 30W Anker charger.) Within a couple hours it hit 95%, but would not go above that, and when I disconnected the charger, the level rapidly dropped to below the initial 75%. For the heck of it I then tried my 60W laptop charger, but encountered the same result. Yet another DBPower jump starter to return. I absolutely cannot recommend this brand. Like I said, the original DSJ90 bought last Christmas did charge fine, but is it trustworthy? What I do know is that a NOCO jump starter I bought for my wife several years ago works great, and it has been used to jump a completely dead battery. I'm done playing games with DBPower. I'm going to get another NOCO for myself. I'm posting this same review for the DSJ90 and the Z07 models, but the Z07 model review will include a video.
