Watt hours of a car battery
For now. Power = rate of doing work Watts or kiloWatts (1000 Watts = 1 kW.) Energy or work done is measured in Joules. 1000 Joules = 1 kiloJoule = 1 kJ. In one hour at one Watt we use 1 W x 3600 s = 3600 Joule = 3.6 kJ. Battery energy = Volts_average x Amp hours capacity = Watt hour capacity.A 50 amp-hour equivalent car battery should be able to power a 2.5-amp CPAP for 6 hours and a 5-amp CPAP for 2.63 hours with an inverter. With a direct-current connection (no inverter), a car battery can power a 2.5-amp CPAP for 7.34 hours or a 5-amp CPAP for 3.2 hours and still be able to start the car. There are so many variables that go into ... It’ll take 5.5 hours to recharge if you use a 10-watt wall charger.
