MiniBoost DC-DC Battery and Solar Charger

MiniBoost 18A and MiniboostPro DC to DC battery charger with solar inputs rapidly charge the deep cycle battery while you drive.

What is a DC to DC Charger?

The car's alternator provides a source of DC Voltage but it is not suitable to charge DC lithium batteries. However, it will charge non-lithium batteries.

Mini boost pro converts the car DC 12v supply to a sine wave suitable for lithium batteries,

What is the difference between MiniBoost and the Pro version?

  • The Miniboost DC charger will charge all batteries except Lithium (LiFePO4)
  • Whereas the MiniBoost Pro is a DC-DC lithium battery charger and charges all batteries. Gel, AGM/Wet, Lithium LiFePO4

Why do I need a DC-DC Battery Charger?

  • If I turn off my ignition, will MiniBoost drain my car battery? No, the car battery is isolated when the ignition is off.
  • Will MiniBoost allow a back feed to charge my car battery when charging my house battery? The car battery is 100% isolated from the back feed even with the ignition ON.
  • I have installed the DC Pro in the rear of my MotorHome. 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.
