Convert 18V DC to 12V DC to power an DC to 120V AC inverter. Maximum Volts on inverters is 15 V A 100 Watt inverter uses 8 - 25 amps. General rule 10 Watts per Amp Cigarette lighter version 8 A (100 watts) Stand alone version 25 A A modem and router will use 15-30 amps (180 - 360 Watts) 24V transformer will output 0.3 - 0.6 ampsSwitching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators, which are simpler circuits that lower voltages by dissipating power as heat.
