The iTECHDCDC40 keeps your battery charged no matter the battery type or size. 

The iTECHDCDC40 charger incorporates an MPPT solar controller allowing charge from solar panels or blankets. When the vehicle runs, the DCDC charger will charge via the alternator; when the vehicle stops, the iTECHDCDC40 will continue charging via your solar panels/blankets (if added).

Exclusive to iTechworld DCDC chargers is a function known as Solar Power Priority (SPP) which represents the preference for solar input. This allows you to set your iTECHDCDC40 to use solar input over the vehicle alternator's input at the push of a button. Solar Power Priority places less load on the alternator, is better for the environment and helps to reduce fuel consumption.

Designed and developed in Australia for Australia, the iTECHDCDC40 is IP67 Waterproof, Dustproof and vibration-proof. Built with a heavy-duty metal case uniquely designed to help with heat dispersion, the iTECHDCDC40 is suited and warranted for under-bonnet installation. Mounting brackets are included in the case design, allowing for easy installation in your setup.  

Many vehicles now have smart alternators that do not produce a high enough voltage to charge auxiliary batteries; the iTECHDCDC40 works by enhancing the voltage to the auxiliary battery regardless of the alternator type; the enhancement of voltage is also valuable for overcoming voltage drop from long cable runs to caravans and camper trailers.
