DBPOWER 5000A Jump Starter Portable Battery Booster Pack

Great Jumper worked like it should

I have had 2 other DB Power jumpers in the past, they do run off or rechargeable batteries so you need to replace them after 4-7 years or if you notice the case swelling like mine did after 5 years, I just got this and had to use it the next day for a lawn tractor and then a friends car both started right up , this is well worth the money to have the piece of mind of knowing you have a backup battery to jump vehicles .the units housing feels cheaper than the last version I had but it did the job , Still comes in a nice case for storage and fits in my trucks glove box .

Work good

Very nice

Faulty equipment

Red terminal disconnected in a matter of weeks so it no longer charges and caught fire... Straight garbage

Charging Issue

I had high hopes but unfortunately ended up returning it. It wouldn’t charge more than 75% even after I tried to charge it for hours. Also the light wouldn’t come on.

Defects product.

It not charging straight out of the box.

I need a replacement...

I googled and tried everything

Nothing works..

Won't last too long

Worked good for 1 yr. Then came apart

It won't work after only 6 times. Owned little less than 7 months.

I bought this 7 months ago. I have used it approximately 6 times to start my lawnmower. It will no longer charge. It has a red light and whistles. It was a lot of money to use only 6 times.

Doesn’t work .

I’m having the same issues as another reviewer it won’t charge up it immediately losing the charge when disconnecting. Bought this as a Father’s Day gift. It’s past the return window not sure what I can do do with this 😕

They don’t backup there products!!!!!!!

I bought one of these and it turned out not to be any good from the start. I went through vigorous troubles to get a replacement and the second one was junk to. This product is no good buyer beware!!!!!!!! Bad company!!!!!!!!

THE BEST BATTERY EVER!!!!!

This is the best battery!!!

I have been looking for a portable battery

for my car and speakers. I recommend this battery!!

I would definitely recommend this unit.

I needed this to jump start my ‘96 Volvo after it had been sitting unused on a solar charger for quite awhile. I hadn’t realized it but the battery had gone bad even with a solar charger connected to it. At the least five years had passed, I guess. I selected this product because I liked the sleek, compact design. When it arrived, I hooked it up to charge with its USB cable and I left it charging from an outlet there on the kitchen counter! My wife didn’t even notice it. That means it is small enough to hold in one hand or to lay under the hood so no one has to hold it for you. It has a flashlight and a charging port for your phone, too. After charging the unit I used it to start my car. I’m pleased with the quality and the features. I would definitely recommend this unit.

More Chinese junk?

More Chinese junk. Manufacturer Can't even put the correct protective plug covers on item. Light does not operate as easily as described. USB ports not identified as being input or output. Instructions indicate 9v input, where is charge port? Do not know if this will start car or not, clamps do not open wide enough to hook to battery posts. Think this may be total waste of money. I have to give it a chance and try to jump start a car.

Iffy...But You Really Need To Read My Review To Understand

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.

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.

Find a different unit with better clamps

The cables are very short and the cheap plastic clamps are very bulky. Too bulky for most small engines. I have a very accessible battery on my motorcycle and I could barely get the clamps to hold onto the bolts.

There is no way that this would work for 20 vehicle jump starts; I had a low (not dead) battery on my motorcycle so I figured that I would test it out. Dropped to 86%!!
