After owning a few portable jump starters from DBpower, it was time to check out and review their latest, and best mini jump starter to date. It’s the DBPOWER G15 2500A. It has a huge 21800mAh internal battery. It may be small in size but it can jump-start car 8.0L gas engine or 6.5L diesel engine.
The big drawcard on this mini jump starter is its size. It’s literally the size of an iPhone 8 plus, so it can be stored away easily. If you have a small family 4-cylinder car, this is the emergency booster pack for you.
It is nice to see DBpower updating their older range of small jump starters like the DJS-40 300A into this new powerful beast.

How to Recharge DBPower G15 Car booster.
Make sure to charge this micro-jump starter at least once every 4 months. This will avoid shortening its lifespan. Keeping the battery pack topped up will reduce the battery from completely depleting over time. If you do use it to charge phones and tablets, it’s also a great idea to top it up.
Don’t keep it plugged into the charge port for extended periods of time. Just recharge and disconnect.
Try to store your car booster pack in a cool and protected place. Extreme temperatures may damage the internal battery. Under a passenger or driver’s seat or in the glove box are ideal locations.
The Dbpower 2500A mini battery jumper is compatible with 8L and lower gas engines. It can also start motorcycle, ATV and jet-skis.

If your car battery booster pack has less than 25% charge capacity, it may not be able to start your engine. This is because car starter motors require a large sustained in rush of current. With a nearly depleted lithium-ion jump starter, the reserve capacity will not be enough to start your vehicle.
Do not connect the positive and negative polarity together when it’s power on.
Be also aware of some fake DBpower units being sold on places like eBay. Make sure to buy from a repeatable store or online supplier like Amazon. The last thing you need is a failure in your compact jump starter.

Jump starting a Toyota Prius
Most gasoline or petrol cars will have the same procedure for boosting a flat battery. Where this change is if you have a hybrid car, like the Toyota Prius. It’s a slightly different procedure.
Basically, you have to locate the fuse box, which is on the right-hand side in the engine bay. Remove the cover and then find the main red battery terminal. Open the red flap, shown below and put your jump starter positive lead onto it.
Connect the negative to a metal part of the car, and you are good to try to jump-start your Toyota Prius. Once your car has started you can disconnect your starter leads and put the fuse cover back on.
This DBpower 2500A is the perfect jump starter for your Prius. This is due to the smaller 1.8L engine, so it is well sized for the job. So why do I recommend it, well it worked for a guy at work who had a flat auxiliary battery in his Prius and needed a jump start.
I’m against using pure jumper cable leads, as so much can go wrong and there is no safety protection. So I just grabbed my micro-jump starter made by DB power and put it on and we got it started. He was so amazed. I just gave it to him for a few days while he went to get his battery replaced.
Update: As so many of you had asked for a more detailed procedure on how to Jump Start a Toyota Prius as well as replace the Auxiliary battery in the rear boot. We have done a whole write-up on the steps required. You can read all about what’s involved.
DBPower 2500A Peak 21800mAh portable review
After using this unit for a few months I can honestly say it’s a great quality unit. I had given it to the kids to use for our road trip. They used it in the car to charge their phones and tablets a few times each day. Giving the compact starter a top-up each night, we could make sure it never missed a beat over the 7-day road trip. They thought it was one of the best mini jump starters they had ever used due to the compact size. Before we used a larger model which sometimes just was awkward and heavy.
Our Toyota Corolla is under 2.5L engine size so we were able to test it out using an old battery we installed into the car to simulate a flat battery.
The car fired up fast with plenty of power. We tried it a few more times and there was no loss of power from this little pocket-sized car battery jumper. The only problem i have doing tests like these is having to reprogram my car radio again.
Recharging the unit was simple and easy from either a phone wall outlet charger or the car cigarette lighter port if you have one. The micro USB port is the charge port and can recharge at the rate of 2.1 Amps depending on the charger type you use. The included cable is Micro USB so it can be used to either charge the unit or use it in reverse to charge phones and tablets.
At the end of the day, this mini battery jumper is a keeper. As a brand DBpower is hard to beat. They make some top-rated jump starters as well other electronic gear, so they really know what they are doing. With over 600 positive reviews, you can rest assured knowing that you are buying a quality reliable unit.
Why we picked the DBPower over others?
The DB Power range of starters has been a favorite in our family. They just work and have never let us down. They also cater for the average man with realistic prices. We actually did a full comparison the other month on 5 of the Top Selling 8000mah pocket size jump starters and with all the features and price taken into effect, this starter came out in the top again. No wonder so many people give it 4 and 5-star reviews.
As this is the big brother model in the DBPower range it has the most grunt. If you would like some extra starting power or extra charge for your devices, check out our review of the smaller 1600A jump starter model. Both have that extra starting juice for 6 and 8-cylinder engines. They also have 2x USB out ports for multiple phone charging. Check them out if you need more features.
For a cheap pocket-size car battery jumper, you can’t go past this little gem. The DB Power 2500A is small and powerful. It is well suited for small to large-sized cars. It will do it all.
