Assuming 100% efficiency, a 36-volt battery charger would use 36 watts per hour to charge the battery fully. However, it's important to consider that chargers are not 100% efficient and may draw slightly more power from the wall.
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.
A mini refrigerator uses about 70 watts per hour or 0.07 KWH.Therefore it uses about 24 times 0.07 KWH, or 1.68 Kilowatt Hours per day.There are varied sizes of "mini refrigerators" and varying degrees ofinsulation, so the wattage may vary from 40 watts per hour to 100 watts per hour or .96 KWH to 2.4 KWH per day
The number of watts used per hour is defined as a watt-hour or "wh". Electricity is normally billed as kilowatt hours or 1,000 watts per hour. Your electric bill will give you KWH number for the month so you could divide this by (24 x 30) to get an hourly average. As an example of the wide range of usage I have a town house rental that used 20 KWH in a month, and another large residence that used 2,900 KWH in a month. In this case the smaller house averaged 27.7 watts per hour and the larger house 4028 watts per hour.This answer is incorrect. A watt hour is not 'the number of watts used per hour'. It is the number of watts times the number of hours. There is no such thing as 'watts per hour'.

100 watts
3/4 of watts
Volts per hour is an invalid statement. You may have meant Watts per Hour.
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
There is no valid conversion.

Hi well kilo means 1000 so thtas 1000 watts per hour

the answer for how many watts a cellphone is.....around 10-16 watts a daymany watts my friend, many wattsThe phone uses 10-16 watts a day.i dont know how many watts it carrys but if i guest it probably 25watts if you find out tell me mahalo
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
