DC-DC Chargers While Driving
(Products quantity: 99)DC-DC chargers are used when the leisure battery needs a controlled charge from the alternator while driving. This section includes units with different charging currents and profiles for camper and van electrical systems. If you are comparing this setup with simpler charging control, see also battery isolators.
This category covers 12V systems where a direct alternator connection is not enough for proper charging. When choosing DC-DC chargers, check the charging current, battery chemistry, and how the unit handles real vehicle conditions. Popular options include Victron Energy and TBB Power, plus models with added functions such as alternator protection, charging profile control, or MPPT integration. For larger camper electrical setups, cable length, cooling, and voltage drop protection also matter. If the charging system is built around a split-charge layout, the range in battery isolators can be a useful reference.
