MiniBoost DC-DC Battery and Solar Charger

MiniBoost 18A and MiniBoostPro 30A DC-DC chargers rapidly charge the deep cycle battery while driving.

What is the difference between MiniBoost and the Pro version?

  • The Miniboost DC charge will charge all batteries except Lithium (LiFePO4)
  • Whereas the MiniBoost DC Pro charges all batteries. Gel, AGM/Wet, Lithium LiFePO4


  • If I turn off my ignition, will MiniBoost drain my car battery? No, the car battery is isolated when the ignition is off.
  • When charging my house battery, will MiniBoost allow a backfeed to charge my car battery? No, the car battery is 100% isolated from the back feed, even with the ignition ON.
  • I have installed MiniBoostPro in the rear of my motor home. Can I use an isolation switch on the blue wire instead of running it up to the front ignition of the motor home? Yes, as long as you remember to switch it off when not in use; otherwise, your car battery can be drained flat by the house battery.

BMPRO’s MiniBoostPRO is a compact DC-DC charger with solar input specially designed for the RV market. The MiniBoostPRO effectively charges your caravan, 4WD or camper trailer’s house battery from the towing vehicle’s electrical system.

Blending solar and auxiliary inputs, the MiniBoostPRO provides a combined charging current of up to a maximum of 30A, with a preference for solar. It features proprietary technology designed to charge from modern car alternators.

The MiniBoostPRO provides a multi-stage charging profile.

It functions when wired directly to 12V batteries and enhances BMPRO’s BatteryPlus35 and J35 battery management systems.

A range of protective features built into the MiniBoostPRO will guard your caravan or camper trailer’s charging capacity.
