When it comes to car accessories, few things are as important as having a dependable jump starter on hand for those inevitable dead battery situations. After plenty of research, I settled on this particular car battery jumper, and I couldn't be happier with my purchase. Right out of the box, I was impressed by the quality construction and solid feel of this jumper. It has a rugged, heavy-duty vibe that inspires confidence in its ability to handle tough jump-starting jobs. The hardshell carrying case is well-designed and it looks nice too. But the real test, of course, is in its performance - and this jumper delivers in spades. I've used it multiple times to revive dead batteries in various vehicles, from compact cars to pickups. No matter the engine size, it fires them up without issue. What really puts this jump starter over the top for me is just how easy it is to use. The clear instructions make the process virtually foolproof, even for battery jump starting novices. And the built-in safety features, like reverse polarity protection, give me peace of mind that I won't accidentally damage my vehicle's electrical system. As an added bonus, this unit doubles as a portable power bank with USB ports for charging phones, tablets, and other devices when you need a quick recharge on the go. The built-in LED flashlight is also a nice touch for those roadside situations when you need a little extra light. In terms of value, this car battery jumper is an absolute steal. The combination of quality, ease of use, versatility, and reliable performance make it well worth the investment. Plus, it could potentially save you from costly towing fees or repair bills down the road. In my experience, this car jump starter has more than earned its keep. It's solidly built, user-friendly, and just plain works as advertised every single time. I wholeheartedly recommend this product to any vehicle owner looking for an essential roadside emergency tool. You'll be glad you have it when you need it most. Read more
This is a great unit to have. It’s compact and light weight but has plenty of power to get the job done. My next door neighbor came over and needed a jump on his Honda Accord the battery was completely dead got this box out and in 2 minutes he was running. My neighbors response was “I really didn’t think that little box was going to jump my car off”. Need less to say he ordered him one later that day. Read more
I have purchased 2 of these now. One for my car and one now for my teen driver. This has saved me a couple of times. I used it to help a friend too. Easy to use. A must have in my cars. I have only used it to jump start a car(s) so I can't comment on the speed it takes to charge other items, such as a phone, etc. The size is great, smaller than old style jumper cables. It has worked great for me every time. I'll have another teen driver next year and if he gets a car then I will be buying another of these for sure. Read more
UPDATE 09-Sept-2025: I still can't give more than four 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 that is a different, older model that they said has been extremely reliable as a thank you for my time in helping them diagnose an issue with a different model. The one they sent is a different brand (S ZEVZO, model ET 03), but I bet it's really the same manufacture. I like that one because it shows the voltage and current it's charging at. Maybe take a look at that one. 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 (yellow, 500A) review will include a video. Read more
