DBPOWER 5000A/80.66Wh Portable Car Jump Starter (UP to 8.0L Gas/6.5L Diesel Engines) 12V Auto Lithium-Ion Battery Booster with Smart Clamp Cables, Quick Charge, and LED, Storage Bag

Works great. After purchasing one for myself and using for a few years I have purchased several more over the past few years as gifts. These will crank a 454 big block for many minutes and still have plenty of charge left. Much better than jumper cables - no help required to jump start no matter your location. Small for easy storage in glove box, under seat, etc. Highly recommend - get one for your spouse, kids, parents, etc.

I’m really impressed with this DBPOWER jump starter. I used it to start a truck, and it worked perfectly — the engine started in just a few seconds! It’s extremely easy to use, even if you’re not very experienced with these devices. The size is just right — compact and convenient, so it doesn’t take up much space in the car. The battery lasts a long time, and the cables feel sturdy and well-made. Overall, this is an excellent product that gives you peace of mind knowing you can start your vehicle anytime. Highly recommended!

This portable Car Jump Starter does the job. I live in Minnesota. My new battery died, dead ignition lights wouldn't come on. Turned out that I had a parasitic draw from the radio. Pulled the radio power fuse. The DBPower 5000A jumped started that battery, no problem. Its small footprint, crank power, portability are impressive. I've pulled it out of the console and used it several times to jump start cars for neighbors and people in distress at gas stations. What contributes to the quality of the product is the customer service and support when you have a problem. This is a must have you when you travel with your family. Great product, great customer service!

New EDIT; Below, is about mine, bought 2nd. This is about my wife's, bought first. I helped someone jump a pickup this morning. SF parking is tight & the owner asked me to move forward for AAA, who would take, an hour to arrive. (Very common.) 5 minutes to locate the nice (but black) case in her busy, tiny, crowded trunk. 20 seconds to apply it. (I really distrust my wife with jumper cables!) 1-2 seconds to start. She ordered one on the spot... And saved 1/4 of her $150 AAA roadside assists. She will happily help the next motorist, she said. ..... I like this larger unit with more reserve power. Mine arrived half charged, (which is wise for transport,) and, as per the manual. (Fully charge this before using the first time - up to 4 hrs for that initial half top off.) Used on a cold 5.4 L truck, it worked V well. Instant start. EDIT: I'm fussy, but despite my crabbing, I am softening on the lack of an AC charger, and just bought a 2nd unit. NO AC CHARGER is supplied!!! I HATE THAT!!! AND, the supplied cord only ONE FOOT long, so I cannot use it to charge from my vehicle dash usb plug in. I have to drag out my emergency iGen200 to charge this, or wonder which of my chargers can handle such a large battery, without damage. The MANUAL DOES NOT STATE how powerful a charger needs to be in the charging instructions in the front of the manual. It must be ferreted out in the specs in the back of the manual!?! Sheesh - FYI - The iGen indicates ~15w when it's charging. That means a 5v phone charger rated at 3000ma. The manual's specs agree. I suggest that you do Not Use any "fast chargers," as some may exceed 5v. Had I noticed that NO AC Charger was included, I would NOT have bought the.first one, even at the discount I paid. When traveling, all AC chargers seem in short supply. Each device needs its own charger, IMHO. "Borrowing" a charger from Peter to help Paul is a Royal PITA, and finding the required charger rating necessary, is a hassle.

Not going to lie here folks, I figured this was going to be a, "too good to be true" purchase. Well.. Horse-Hockey. Turns out, i was wrong. It works! And when I say, "It works", I mean, "It works" exactly as specified. Sadly, it started an F-250 V-8 in zero degree weather, after it had already started a Solara Convertible with a 5-year old dead battery @ 10-below, not once, not twice; but several times since buying it. Every time I used it, it would drop from 100% to 97 or 96 percent per start. I expected at LEAST a 10% drop. On one really cold day when I had to turn over the Solara twice (the first 3-seconds didn't do it), that particular jump start took it down to 92% charged. IMPORTANT Advise: READ THE MANUAL! Before even touching it, I read the manual. I suggest everyone do the same! Pay special attention to the things they tell you about. For example, don't turn the key over for more than 3-seconds at a time. After each use, WAIT before you re-charge it! Also, about using the button on the side of the battery terminals attachment. About how it doesn't even need to be turned on to jump start a car. Things like that. READ IT, it's a GREAT manual & you'll get much more from the unit by using the product the way they tell you to use it. The flashlight proved handy too. Sure, I have flashlights; but it's nice they include a way to let you see the battery terminals and actually re-read the included instructions before you actually try to hook up any connections! :) The MANY power settings for the other ports are fantastic too. I mean, wow. To think they include so many connectivity and charging options as well. It's mind blowing. Even a Cigarette lighter charger so your car can recharge it after you've jumped started that car? (After waiting the time designated in the manual, following each use). The outside case is well constructed fabric textured hard-shell with included battery surround foam (pictured) for that half of the case. There is even a handy usage chart on the padded divider that separates compartments. My only modification was placing some compressible foam on the battery side of the case specifically so the battery itself isn't rubbing up against the inside of the hard case all the time (I included a picture of this added foam too). In a nutshell, this product was well thought out. It's not a half-measure, it's not an, "almost" what you want. The battery terminal clips are not the cheap junk that I've seen on others jump starters. The manual wasn't written by someone that speaks English only through a translator. No! It's the whole deal. It's well constructed. It's "heavy duty", it includes EVERYTHING you need to Charge or Jump-start anything it is rated for. The manual is VERY WELL written and COMPLETE (and that alone is saying a ton these days). It is well packaged and HAS performed as promised. If abused, I can't say what your results will be; however, I have used and cared for it as indicated in detail in the Manual and so far, I'm just amazed at how great it is. Value: Ha ha ha ha ha. Ask me when you're standing in 10-below weather wondering what you're going to do. It's the Best $70 I've spent this year. My only complaint was not buying two of them!

This brick is a total beast for how tiny it is, and it feels tough enough to handle being tossed around my messy trunk. It’s super easy to use and had my dead engine screaming back to life in basically two seconds flat. It holds its juice forever, so I never worry about it being dead when I actually need a boost. I’ve jumped a few friends already and the battery life is still going strong without even breaking a sweat. Just get one, it’s way better than waiting for a tow!

We are very impressed with this product's performance, packaging and value. Frankly, we were skeptical it would live up to its billing, but it has. We assumed what we'd get was a good portable power-pack suitable for charging mobile phones, cameras and computers--but jump starting a car? It passed with flying colors (albeit on a small, four-cylinder Hyundai Getz). We were impressed with this unit right out of the box. It's packaged in a very nice and well-made soft-side zippered case that's complete with a raft of accessories and an owner's manual (more on that later). We appreciated the fact that it can be charged via a wall outlet or 12v outlet (cigarette lighter). It charged quickly and has held a good charge for two months, during which time we've charged phones, jump-started our generator and this morning jump-started the car. Living in the tropics, we are subject to frequent power outages ...and if there's a problem with the generator, we're stuck. That was the impetus for this purchase--we needed a way to charge phones if all power was down. It's been great for that, but does much more. Given its ability to charge at different ranges and the wealth of tips provided, it's extremely versatile when it comes to electronics. When the battery on our generator went dead, we were able to use this to jump start the generator. And now we've jump-started the car. Impressive performance for such a small but well-built package. Given all that it can do, the quality of the unit and the accessories, and the surprising power, we have found this an excellent value. And it's small enough to pack along and provide power in a pinch. Frankly, the only small disappointment was that i was initially underwhelmed by the instructions, which I found a bit confusing. I could't get the trouble light (which provides a steady beam as well as two flashing modes) to work. I now attribute that to operator error and the directions for jump-starting worked like a charm. I am, however, not sure about the compass, which could easily be left out without affecting the value in the least. It just seems a bit gimmcky to me given the strong electromagnetic fields that must be generated, but it works better than expected. Overall, we are delighted and very impressed with this combination of power, versatility and value.

Purchased this product based on the positive reviews but what I failed to notice was the consistency in the negative review with regard to faulty or defective item. The first item that I received was totally dead. When the power button is pressed no indicator lights are on at all and other signs of life. Tried to contact customer service several times but their response always was 'agents not available'. I went on the 24 hour chat service twice and the experience was pathetic. The agents had no clue on the product and their response was 'send us a video showing the problem'. Really! they want a video that shows nothing happening when the power button is pressed! Since the item was totally defective I decided to return it and reorder it hoping the second order would be Ok. Well sadly the second unit was also defective and unusable. This time when the power button is pressed all four indicator lights flashed (instead of seeing solid lights on indicating how much charge there is in the unit). Again the customer service phone call response was agents not available, and the chat agents had no clue what four flashing indicator lights mean. I thought I'd give it one more try and order another one as what are the chances that the 3rd unit would also be defective. When the 3rd order arrived I was so happy to see that indicator lights actually worked and correctly showed in solid lights the charging status. However after fully charging the unit I took it to the car and connected the alligator clamps to the battery through the dongle device. Well guess what, the display on the dongle showed the dotted rectangular frame going around and around with no other indications or code. Tried again and again and same thing kept happening. At this point I was sure this product is not only total trash but even if it had worked with the initial testing how would one trust that it would work when you're stranded and badly dependant on it. One would wonder if this company had any QUALITY CONTROL how would they have missed these 3 cases. I hence returned the 3rd unit and planning to go for the Noco BP40 which is an established company with US support.
