Juggling your 12V setup so that the beers stay icy cold, and the lights will come on at night can sometimes get pretty complicated. Our 25A DC-DC Charger with MPPT Solar Regulator takes the confusion out of your battery setup. Perfect for everyone from weekenders to off-grid tourers, our charger is ideal in setups using Lithium, AGM/Gel, Lead Acid or Calcium Batteries.

Our DC-DC Chargers will charge your batteries at up to 25A for every hour you drive. Compatible in vehicles using either a traditional or fixed/smart alternator, our DC-DC will charge your batteries using a five-stage charging algorithm, overall prolonging the life of your auxiliary batteries.

The second output on the charger is our inbuilt 25A Maximum Power Point Tracking (MPPT) regulator designed to generate power up to 15% quicker than traditional Pulse Width Modulation (PWM) regulators. Equipped with our five-stage charging algorithm, the regulator will quickly and, more importantly, safely, bring your batteries back up to full charge.

Its compact construction means that the unit will fit most smaller setups including inside some battery boxes or tight 4×4 canopies.

Our DC-DC is compatible with the “Hardkorr DC-DC Charger” app, available on the Google Play and App Store. At the press of a button, the app will give you access to a live feed on your batteries, solar and DC input.
