TEMO 1000 12V Charger. Charge your TEMO 1000 conveniently aboard your boat using the specially designed 12V charger, compatible with standard cigarette-lighter sockets. With an output of 110 watts (up to 9 amps at 12V), a full charge will consume approximately 90Ah at 12V, taking around 12-1/2 hours from empty. The charging connector on the TEMO 1000 is waterproof and IP67 rated. However, ensure both the connector and charger are dry before plugging in to avoid short circuits or sparks.
