Imazing IM29 Portable Car Jump Starter Features and Specifications

Imazing IM29 Portable Car Jump Starter features starting current of up to 1000 Amps and a maximum peak current of up to 2500(!) Amps, which is enough to crank gas and diesel engines up to 8 liters.

The unit comes with an internal lithium-ion battery which is able to store up to 74 Wh (20000 mAh, 3.7V) of energy and release it at the moment's notice.

Theoretically, a new, fully charged battery is able to provide up to 30-33 engine starts, however, in real life, the number of starts depends on the battery condition, temperature, age and charge, car's battery condition, local temperature, engine type, size, and condition, etc. and ranges usually from 8-10+ engine starts.

Imazing IM29 Portable Car Jump Starter is very simple to use and maintain lithium car jump starter, but when it arrives, be sure to read the manual and keep it in the carrying bag.

Imazing IM29's physical dimensions are 7.72 x 3.42 x 1.58 inches (196 x 87 x 40 mm) and it weighs 1.42 pounds (644 grams), which isn't much for the 74Wh/1000 Amps jump starter.

The operating temperature of the unit is -20°C to +60°C, with a charging temperature range of 0°C to 60°C.

Since lithium-ion batteries perform best at room temperature, it is highly recommended to store and charge the unit at room (15°C - 25°C) temperatures.

Note "*":  Lithium-ion batteries perform best at room temperature - if possible, charge ALL devices with lithium-ion batteries at room temperatures (15°C to 30°C) and keep them away from the sunlight!

As one can see, they are all very versatile units - personally, keep your jump starters fully charged and use other devices like power banks and solar generators for recharging devices like smartwatches, smartphones, tablets, laptops, and similar.
