Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
As watts equals volts times amps (ohms law simplified) you are missing part of the equation.. Let's say you are asking about how many watts is 1 amps at 12v then... If W = V x A then 1A at 12v = 12 watts
The formula you are looking for is I = W/E. Amps = Watts divided by Volts.
In ideal conditions, about 6W Amps x volts = watts 500ma = 1/2 amp (1000ma to 1a) 0.5 X 12V = 6W
Watts = amps x volts. Amps = Watts/volts = 200/12 = 16.66.
Approx 5 hours
A 10 amp 12 volt charger.
10
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
200AH =39x5 approximattely, so 1 batteries enough for 5 hours you need 3 batteries to keep runnimg 12hours

That would also depend on battery chemistry.
You need to know the volts of the device to answer the question, if it's a household appliance (120v) then the answer is 36 watts, if it's an automobile device (12v) then the answer is 3.6 watts
The formula you are looking for is I = W/E. Amps = Watts divided by Volts.
In ideal conditions, about 6W Amps x volts = watts 500ma = 1/2 amp (1000ma to 1a) 0.5 X 12V = 6W
Approximately ten amps available at the lighter's socket. Ohm's Law thus gives 12V x 10A = 120 Watts...
well the equation for amps is a= watts/volts so 25/12= 2.0833333333amps
