Imazing IM39 Portable Car Jump Starter Features and Specifications

Imazing IM39 Portable Car Jump Starter comes with ~99 Wh (3.7V 26800 mA) lithium battery which can ensure, in theory, 30-40 start attempts.

In real life, a number of start attempts depends on the engine size, type, outside temperature, vehicle's battery condition, etc. - Imazing IM39 comes with a very respectful battery and energy-efficient electronics, ensuring 10+ starts/cranks on a single battery charge.

The unit features physical dimensions of 9.65 x 3.86 x 1.81 inches (~245 x 98 x 46 mm) and weighs 3.25 pounds (~1.47 kg) - unit is compact and lightweight enough to be easily carried in a backpack, for example.

Imazing IM39 features several ports, including:

- USB Type-C 3A Input/Output port,

- USB1: 5V/3A, 9V/2A, 12V/1.5A,

- USB2: 5V/2.1A,

- DC: 12V/12A,

- 12V Smart Clamps port.

The unit is recharged via USB Type-C 3A Input/Output port (cable comes with a unit) and when the battery is fully discharged, it takes up to 12-13 hours to fully recharge the battery again.

Note: thanks to the large battery, Imazing IM39 can be used as an excellent portable power bank - it can recharge smartphones, tablets, and other devices. But, if the battery is discharged below a certain level, the unit can't be used to successfully crank the engine, which is its original purpose.

The additional feature of the Imazing IM39 is the LED flashlight which features three light modes - Light, Strobe, and SOS. The light can come in handy in many situations, especially when starting the car in low light conditions.

How to Start the Engine Using Imazing IM39?

Imazing IM39 is a very simple to use portable car battery charger that comes with numerous safety features, including reverse polarity, reverse connection, over-current, overload, over-voltage, over-charge, over-discharge, and short circuit.

However, when the unit arrives, be sure to read the manual and to keep the manual in the unit's carrying case.

The actual procedure is very simple:

- turn On the Imazing IM39,

- Insert the starting cable in the unit,

- Connect the clamps to the battery,

- Start the car.

And that's it - remove the cables and recharge the unit right away.

Despite having so many safety features, don't let the clamps touch each other, just in case.

Long Story Short: If You are looking for a versatile unit, but primarily intended as a car jump starter, consider Imazing IM39 - it features a peak current of 4000(!) Amps, ~99Wh battery, numerous safety features, and in the end, it gets its job done.

Also, Imazing IM39 can be used as a power bank and as a flashlight - a LED flashlight allows the user to crank the engine even during the night.

However, using this and similar units as portable power banks can be a double-edged sword - personally, use it to charge only telecommunication devices to make emergency calls and nothing more. And as soon as the engine starts, recharge it.
