Noqon NBS30 Solar Charge Booster with integrated Solar Charge Controller 30A

NOQON Charge Booster: NB- & NBS Series

They provide freedom and save time: the NOQON Charge Boosters of the NB and NBS series. The letters NB in the series names stand for "Battery Booster," specialized devices for battery charging. What sets the NOQON Charge Boosters apart from conventional chargers is that they allow charging a 12-volt battery using another 12-volt battery (Battery-to-Battery method, or B2B for short). The charging process is controlled: the charge booster continuously monitors the battery through the measurement lines to ensure that neither the supply battery is overcharged nor the starter battery is discharged during travel.
