How Many Amps Does A 12v Tv Use. How much electricity TVs use varies by type manufacturer and size. To support 75 amp hours of battery power 150 amp.
Watts Volts Amps per hour A slightly different example is a 60 watt fridge running on a 12 volt power source uses 60 12 5 amps but only while the motor runs. Then to allow for inverter efficiency typically 85 divide the figure by 085. So to work out the amps at 12 volts you divide 300 watts by 12 volts and you get 25 amps.
You can determine power characteristics of an appliance if watts rating is not provided by the following equation.
Fluorescent light double 30 W. This is the DC current the inverter will use to operate the 1500 watt load. Watts Volts Amps per hour A slightly different example is a 60 watt fridge running on a 12 volt power source uses 60 12 5 amps but only while the motor runs. 39 Watts 28 Amps 40 Watts 33 Amps 60 Watts 5 Amps.
