Skilled Camouflage
The device features a compact body measuring 168x88x33 mm and weighs just under half a kilogram. Externally, the model can easily be mistaken for a regular power bank — except for the presence of a power connector for attaching a cable with "crocodile" clamps, which reveals its true purpose. Through this cable, car engines can be started in case of a low battery or in cold weather.
Lithium-Cobalt Battery
The Osram BATTERYstart 300 is based on a rare type of battery — a lithium-cobalt (LiCoO2) with a capacity of 13000 mAh. The nominal starting current of the device reaches 300 A, and in peak mode, it increases to 1500 A. Thanks to this, the booster is capable of starting gasoline engines up to 6 liters and diesel engines up to 3 liters.
A Pair of USB Ports
The model indeed resembles a classic power bank, as it can share stored energy with mobile devices. For this purpose, it has two USB-A outlets with an output power of 18 W each. It also includes a bright LED flashlight and a four-segment battery level indicator with an on/off button.
