Don’t Buy The DBPower 1200A Portable Jump Starter For Your Car or Truck – They Will Not Last

In August 2016 I bought a DBPower 400A DJS10 Peak jump starter amd found it handy. At the end of August 2018, I bought two of the bigger 1200A portable jump starters. I was busy and the units sat until some time in November when I tried to charge them. One was dead on arrival and would not charge no matter what method I tried (USB or their supplied charger). I contacted the seller and they were cool about immediately shipping a replacement. I charged it no problem and put both in our cars as a “just in case” measure.4

So, fast forward to February 1, 2019. Michigan was in the grips of an arctic freeze with ambient temperatures ranging from -8 to -12F and windchills under -20F. It was this way for two days. On the first, I went to start my wife’s Camry for the first time in several weeks and the starter could barely turn a few times before the solenoid clicked. The battery read 11.17 volts.

I thought myself lucky that I had the foresight to buy the batteries as I would not have to move my truck around to jump start it or run an extension cord out to use one of my Noco Genius chargers. The DBPower unit had been in the car and it was about +9F at the time. The whole point of these things is to store them in the car, right? It was fully charged when I put it in there.

Guess what? The DBPower read “Lo” voltage on the LED display when I turned it on and tried to charge the battery. It didn’t help the cart start at all. I was pissed. These things were $72.99/each. I felt like I had wasted a ton of money on junk. That is not a good feeling.

So, I decided to run an extension cord from my shop and hooked up my big Noco Genius G2600 charger to the battery and set it to the 30 amp quick charge setting that runs for five minutes.

This time around, the story ends a lot better – the car started right up. My wife used her car to run errands and I let it charge all last night with the normal charging cycle on the Noco.

4/16/19 Now, DBPower did make things right and replace both units and told me I have to charge the units every two months to have reliable power. If you open a unit up, you will find out they have Lithium Polymer (LiPo) power cells. These can hold a big charge and discharge quickly but they lose the charge as they sit – typically in about two months.

12/6/19 update- still working just fine as long as I keep them charged.

12/21/19 – pulled one out of our van. It’s been there since probably Labor day and the battery is at zero. I’m charging it now. What I am finding with these things is the you need to top them off every 2-3 months. The Noco charger holds a charge far longer than the DBPower unit. I charged the Noco early on the summer and it’s between 50 and 75% right now according to its status LEDs.

7/14/20 – Have now thrown away two units because they don’t buy a charge. Seriously, do not buy a DB Power unit and buy a Noco jumpstarter instead. My Noco holds a charge and has had zero problems.

11/5/20 – Throwing out my last two DBPower units that no longer hold charges. The Noco is still doing just fine and I plan on buying a second one.
