The ROOKS SMART OK-03.0021 is an electronic charger for 12 V and 24 V lead-acid batteries: 2.2-230 Ah at 12 V and 14-120 Ah at 24 V. Its microprocessor detects the battery's type and condition and sets the charging parameters itself, and charging runs in 10 fully automatic stages. It handles WET, MF, GEL, AGM, EFB and CA batteries in cars, motorcycles, trucks and other vehicles, for charging and maintenance in workshops, service shops and service stations as well as at home.

The charging current is 2 A or 8 A at 12 V and 4 A at 24 V. The digital LCD display with a built-in voltmeter shows the charging parameters in Polish or English, and LEDs signal the charger's state. The charger protects against overheating, reverse polarity, overload and short circuit, a cooling fan gives thermal protection, and the housing is rated IP65 against dust and moisture. An accessory kit with crocodile clips is included.
