The perfect link between vehicle battery and appliance, combining what was never intended to be combined. If the 12-volt navigation system is powered by the 24-volt on-board battery and the 24-volt coffee maker easily copes with a 12-volt supply, there’s bound to be a PerfectPower voltage converter somewhere along the line.
PerfectPower voltage converters have an electronically regulated output voltage, to which they owe their extra function as a high-quality IU charger.
