The Renogy 12V 20A DC to DC charger takes power from your vehicle's alternator or starter battery and charges a second, auxiliary battery bank while you drive. It is a second-generation unit that reduces output in high heat to protect itself, and it detects when the alternator is running so it does not drain the starter battery. Bluetooth through the BT-2 module lets you monitor charging and log 365 days of data in the DC Home app, where you can also switch lithium activation on or off. It suits van, camper and overland builds charging a modest house bank; 20A is a small output next to 40A and 50A DC-DC units, so it is best for smaller banks or vehicles with limited alternator headroom.
