Two formulas are needed to calculate the answer:
[Energy (watt-hours)] = [Power usage rate (watts)]? x [Time (hours)]
and
[Power usage rate (watts)] = [Voltage (volts)] x [Current (amps)]?
If you run it for 3 minutes and off for 57 minutes each hour, it would save 95% of the energy.
Different appliances have different wattage draws. Without knowing the wattage of the appliance, an answer can not be given.
Running a power of 60 watts for one hour uses 60 watt-hours of energy. If you run it for two hours, that would be 120 watt-hours. Running a 60 watt appliance for 16 hours and 20 minutes is 1000 watt-hours, or 1 kWh, also called one Unit.
The cost per day to run a freezer can vary depending on factors like its size, age, and energy efficiency. On average, a freezer may cost between $0.50 to $2.00 per day to operate. To calculate the specific cost, you can refer to the appliance's energy consumption rating and your local electricity rates.
Everything will run out of energy without an energy source.
Most new appliances have a power rating label on them. The Energy Star label is an indication that the appliance is more energy efficient than others and will tell you how much the appliance will cost you to run. Appliances that do not have an Energy Star label are not a good investment.
A refrigerator uses electrical energy as its primary source of power to run the compressor, fans, and other components that cool and regulate temperature inside the appliance.
If you run it for 3 minutes and off for 57 minutes each hour, it would save 95% of the energy.

It is best to run the appliance at the voltage for which it was designed. Frequently Stoves, Clothes dryers, Air conditioners, Heaters, and a few other appliances with their own circuits run on 240. Most household appliances that are plugged in run on 120. Outside of Baltimore, Maryland, one subdivision heated houses with 480 volts. One man worked on his own heater. He was electrocuted. What he did would have caused a spark with 120 volts, not an electrocution. Higher voltage usually costs less to run if the appliance is designed for higher voltage.
Yes, if the appliance was designed to run on 210 to 240 volts.
It depends on how much current is being drawn. If your device draws 1 milli-amp of energy, it will run for 900 hours. If your device draws 450 milliamps (mA) of energy it will run for 2 hours.
Nowadays, most refrigerators use electrical energy.
Power = energy / time Energy = power x time If you operate an electrical appliance for a while, then the amount of energy it used is (power it uses when it's turned on) times (length of time it's turned on). (power) x (time) is the amount of energy used. That's what you're billed for, and what you pay your local utility. Turn on a 1-KW appliance, and run it for 1 hour, it uses 1 kilowatt-hour of energy, and that's what you'll pay for.
there should be a sticker somewhere on your appliances, usually on the back or the bottom, showing the volt and wattage requirement of that appliance. just add up the appliance requirement on each appliance that you need to run without going over what your generator is rated in output. any appliance repair technician should be able to help you with this.
