12V Vehicle Adapter for Dual Slot Battery Charger (Spectra-Precision)
The Dual-Slot Battery Charger can be powered by a vehicle voltage of nominal 12V. The 12V Vehicle Adapter is suitable for use with standard 12-volt vehicle power sockets. It can withstand voltages of a vehicle voltage of nominal 24 V (maximum 32 V). So if the user connects the vehicle cable by mistake to a 24 V socket in a vehicle the charger does not start charging but latches in a fault condition and flashes all green LEDs.
