Imazing IM27 Portable Car Jump Starter Features and Specifications

Imazing IM27 Portable Car Jump Starter features physical dimensions of ~7.5 x 3.5 x 1.4 inches (191 x 88 x 36 mm) and it weighs ~1.14 pounds (518 grams).

Note: in real life, the number of engine starts depends very much on actual battery condition and charge, car battery condition, engine condition (cold, warm), local temperature, and similar - for most passenger vehicles, one may expect at least 8-10 successful starts on a single battery charge. And yes, after each start, it is highly recommended to let the battery cool down and recharge it right away.

If the starter doesn't crank the engine after 4-5 times, there is probably some other problem with the car, not just discharged the car battery. After each attempt, it is recommended to let the unit cool down for at least 2 minutes.
