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
In ideal conditions, about 6W Amps x volts = watts 500ma = 1/2 amp (1000ma to 1a) 0.5 X 12V = 6W
A typical 12V starter motor for a car can range from 500 to 2,000 watts, depending on the size and design of the motor.
To calculate the amperage, use the formula Amps = Watts / Volts. In this case, 18VA is equivalent to 18 Watts (VA = Watts for DC circuits), so it would be 18W / 12V = 1.5 amps.
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

Approximately ten amps available at the lighter's socket. Ohm's Law thus gives 12V x 10A = 120 Watts...
