DBPOWER 300A 8000mAh Portable Mini Car Jump Starter, Emergency Battery Booster Pack, Power Bank with LED Flashlight for Phone Tablet and More, 2.5L Petrol Engine Max (Black/Red)

live saver, so cheap and reliable. our honda jazz had an empty battery - we left the lights on over night. not even remote control worked anymore. connected the powerbank as per instructions and it worked immediately - and the charge was still 100%.

I bought two of these. One for my parents and one for my grandparents. More to have it a not need it rather than needing it and not having it. Just 2 days after ordering a friend at a pub my dad was in needed a jump for his daughters car. My dad promptly got this battery with a smirk on his face excited to try it out. A bunch of blokes laugh at him not expecting a small bit on plastic to have any impact. As simple as 1-2-3 the car was started, the blokes were left red faced and promptly ordered their own.A great product at a dam good price.

I bought this little gem to start my 1.3 Petrol ignis when the door got left open. I thought it didn’t work having ‘I thought’ followed the instructions but when my son showed me where I’d gone wrong it started it no problem. A few weeks later my sons 2 litre diesel developed a fault where the battery was running down while his car was stationary. This amazing piece of kit has been starting it over and over again while we try and find out why and who can fix it. Worth every penny I’ll be ordering another. Came quickly and well packed.

I wonder if I have one with a fault or one which is a fake.No way this is 8000 mA·h battery size. I tried charging a Ipad mini 2 which has a battery size of 6471 mA·h which had 10% battery life left, there should have been enough charge to fully charge the Ipad but only got to 65%, the DBPOWER 300A should have fully charged the Ipad and had some power left. Which means the battery size must be even smaller.I have tried recharging the DBPOWER 300A to see how long this would take, It took 2hr 50min lets round it up to 3hrs to calculate what the size maybe @ 2.1v which would be the max load which is 6300 mA·h which would have been more than enough to charge the Ipad.

I only purchased this yesterday as a deal on Amazon as my daughter has just started driving and I knew with the cold weather it may come in handy one day for her little old Ford KA. Eight o'clock tonight my doorbell rang today with my neighbour at the door saying my daughter had left her car lights on. Panic straight away came to mind with having to dig out the old battery charger or jump leads from the shed, then I realised I had my new DBPower supply fully charged. I opened the bonnet of the car turned the key and it turned over briefly then the battery died. With my neighbour looking at me as it "I told you so..." I then dug out the DBPower supply and connected it to the battery terminals. My neighbour seemed very confused that such a small little box would be able to power the battery to start the car. With one turn of the key, the car started and made me feel very very pleased with myself and impressed my neighbour.This is one of the best purchased I have ever made on Amazon and can highly recommend this for anyone having a daughter or son with their first car as it also backs up as a phone charger as well and fits neatly in the glove compartment. I am not sure how long it holds its charge but after starting the car it still showed 100%.I am going to purchase another one for my wife to keep.

This really goes to show how technology is always moving forward. When I passed my test in 2008, I was driving old bangers and carrying a jump starter in the car was a necessity. That thing cost me around £60+, was in the region of 10-15KG and took up the whole spare wheel cavity with its size. Just ten years on and wow!!! This thing is pocket-sized, weight isn’t a problem and best of all cost me only £25. I guess that’s the benefit of modern lithium batteries.This was bought as a ‘hopefully won’t need but nice to have peace of mind’ item. Therefore, I haven’t been able to put it to the test yet. That said, based on the many positive reviews I have every confidence it will work fine when needed. If I ever need it just once, it will have been worth the cost. I do have breakdown cover, but who wants to wait around for them to come and jump a flat battery? Even if I don’t need it myself, at some point I’m sure I’ll be able to help out a family member, friend or colleague .

Over Christmas, I found myself having to wait over a week for a new car battery to be delivered. My existing car battery was virtually dead. I asked a local friend to use their battery pack to get it started. He came round with an enormous box and sure enough, got it working. However, I knew that I had 48 hours of driving to do with multiple stops, so I took a punt on this clever little product. How glad I am that I did!The power bank is pretty much the same size as my other mobile phone power banks - fitting easily into my pocket. It is robust and very well made. The instructions are clear. The jump start leads that come with the device are high quality and I was easily able to attach the crocodile clips to the appropriate parts of my battery. I tried to start my car without using it, and got no engine turnover at all. I then attached the power bank and my car started first time. It was pretty amazing to be honest. But I then thought, how is this going to manage for the rest of the day. I stopped and restarted my car six times during the first day of use. At the end of the day, the powerbank still had 75% charge! On day two, I jump started the car a further nine times having fully recharged the powerbank overnight. Again, 75% remaining, so I fully charged up my samsung tablet and a motorola mobile phone.Now that I've got my new car battery, I hope that I won't be needing the jump-start feature of this powerbank again. Nevertheless, I've put the leads in my glove-box compartment in the car just in case I (or anyone else) needs it. I'm now left with a fully functioning and highly effective powerbank, together with LED light.Compared to having to hire a car for a few days, this clever little unit has paid for itself many many times over. I wouldn't hesitate to recommend having this in your arsenal whether you've got a dodgy car battery or not. It's simply a brilliant piece of engineering.
