6/12

Suitable for use in older or smaller vehicles with 6 Volt batteries as well as in passenger cars, motorcycles, and small trucks with 12 Volt batteries.

Measured in Amperes (A), it determines how quickly the device can "fill" your battery. The higher the number, the faster the charging. For small batteries (e.g. motorcycle) or simple maintenance, a few Amperes are enough, while for faster charging in cars you will need a higher current.
