 DBPOWER DJS50 Portable Car Jump Starter Features and Specifications

DBPOWER DJS50 is a rather compact and lightweight unit. Its physical dimensions are (L x W x H) 7.28 x 3.54 x 1.57 inches (~18.5 x 9 x 4 cm) and it weighs ~1.33 pounds (~600g).

Unit features an 18Ah 3.7V lithium battery which is being able to store up to 66.6 Wh of energy.

With its 800A peak current, DBPOWER DJS50 is able, according to the manufacturer, to crank rather large engines - up to 7.2 liters gas and up to 5.5 liters diesel engines.

Also, DBPOWER DJS50 is able to provide up to 20 cranks without recharging.

Note: the number of cranks without recharging depends on many things, including the size of the engine, starting battery condition (it is not the same if the battery is almost dead or it just needs a 'little push' to crank the engine), outside temperature, DBPOWER DJS50 battery charger, etc.

In real-life situations, when the DBPOWER DJS50 is used for smaller gas engines, it can pull out 12-15 cranks easily, but if it has to crank large engines (4-5 liters or more, especially if it is a 'frozen' diesel engine), one may expect 4-7 cranks.

Personally, even this is an excellent achievement for such a small and affordable unit.

According to the manufacturer, DBPOWER DJS50 features a broad range of operating temperatures, but personally, it should be stored at room temperature - don't leave it in the car/truck/boat/RV during summer heat and/or cold winter nights.

Note: DBPOWER DJS50 is rather simple to use and maintain a car jump starter/power bank. But, when it arrives, be sure to read the manual thoroughly (it is rather short) and recharge the battery. Also, keep the manual near the unit, just in case.

DBPOWER DJS50 comes with numerous safety features including reverse charge protection, short circuit protection, overcharge protection, overcurrent protection, and 'DO' reverse connection protection.

Despite all these safety features, one must be very careful when using this or any other jump starter - better safe than sorry. Any mistake can damage the unit or prevent the unit from successfully cranking the engine.

When cranking the engine, be sure not to crank the engine for more than 3 seconds. And if repeated cranks are needed, let the DBPOWER DJS50 cool down between the cranks for at least 30 to 60 seconds.

After use, don't charge the unit right away - let it cool down for at least 20-30 minutes.

DBPOWER DJS50 may be recharged using a 12V cigarette lighter adapter charger or wall charger - both chargers are included.


 Additional features of DBPOWER DJS50 include:

- compass,

- LED flashlights: white LED flashlight with High, Low, and Strobe modes and red emergency flashlight.

- USB charging ports: 5V/2.4A and 5V/2.1A

- 12V/16V/19V charging port which may be combined with a 1-in-8 port adapter, allowing the DBPOWER DJS50 to recharge most laptops.

Note: although having a 66.6Wh power bank is great for outdoor enthusiasts, if DBPOWER DJS50 battery charge drops below 50% (especially below 30%), its ability to crank (larger) engines becomes questionable, to say the least. Also, the older DBPOWER DJS50 model featured a 600 Amps peak and 300 Amps initial current and also featured a 'boost' button. The newer DBPOWER DJS50 model doesn't come with the 'boost' button, but it is overall an improved model.
