The RanOx™ Battery Booster is proudly designed and manufactured in Australia by RanOx Pty. Ltd. It suits the rugged Australian conditions, where many travellers wish to spend many days away from mains-powered sites, being self-reliant, but with an ever-increasing range of electrical devices.  We proudly release an updated model, with many enhancements. Transfer mode has now been added, so you can efficiently move charge from your auxiliary battery to your caravan or camper without running your engine. This may remove need for solar or generator. 

We believe the RanOx™ Battery Booster delivers the best (features for price) mobile voltage and current feed to a Caravan, Camper, Trailer or Auxiliary (4WD or Motor-Home) battery available in Australia today. It takes the limited feed from your car/engine and "boosts" it to provide a controlled (multi-stage) regulated supply to this "leisure" battery.  It can also provide the same controlled charging from mains, with a simple cheap power supply. You don't need to purchase a separate expensive mains charger for your caravan/camper/motorhome.

This provides much higher stored charge, prolonging the life of the battery and ensuring maximum capacity to run all those 12V devices at your remote campsite. Please see our graphical proof on the More_Information page. Also please see these opinions by actual Users: Happy_Customer or PradoPoint.

We are proud to announce that the well regarded Kimberley Kamper/Karavan Group recommend RanOx™ as suitable for trailer battery charging from a tow vehicle. 

RanOx™ suits a variety of Lead-acid battery types: flooded (conventional car type), sealed gel-type, deep-cycle type, AGM type etc. It will provide up to 25 Amp of controlled charging current for these batteries, provided adequate alternator supply is available.  In addition RanOx™ will act to protect this auxiliary battery during discharge, by disconnecting loads before "low-voltage" is reached.
