not arguing, I totally agree with you I know the newer units use less wattage but the GE fridge looks to be about 25-26 cu.ft. and the Frigidaire looks to be only about an 18-20 cu.ft. just guessing but the wattage difference is probably due to the larger compressor unit in the GE could you do a video on two same size units so people can see the clear difference? "just trying to help"
Thanks Bill. I was looking for this exactly. I have an off-grid little homestead and the bigger battery drain at nights is the fridge. I'm trying to figure out exactly how much it costs me in terms of battery because rate of discharge pretty much determines how long do they last.
Thanks for making this, I had no idea on what scale a fridge took off power. I was looking if the block I was using (max 2000W) could handle it, everybody keeps mentioning kwh/year what is not as helpfull.
That's funny I have the same fridge as the first one. My power went out and I was trying to figure if my car power inverter would power it. Looks like it will. Thanks
Bill I think is not that simple (50% on a day). I thought all fridges work on demand (a fridge compressor turns itself on when temparature in the fridge reaches certain set point (e.g.10°C) and then when the temperature drops under certain set point (e.g.5°C) the fridge compressor turns itself off. It also depends on ambient temperature, so in the winter the fridge uses less power (turns on less frequently) than in the summer. Also it depends on how much food you have inside and how often you open a door on the fridge (that is why they say ''don't leave the fridge door open for too long'').....so that the fridge compressor will have to compensate for the temperature rise caused by passing outside air (warmer air) into the fridge. And then you have a ice buildup in freezer, if is significant it will also draw more power. That is why the freezer needs to be defrost from time to time. Thanks anyway
So the compressor is turning on and off during the day to keep the fridge temp. Is it true that when the compressor turns on again, it starts like over 1200 watts??
thanks, trying to size an inverter to have an option of using my EV's 12v system as a back up generator per say in the event of a prolonged power outtage. really just care about running a fridge and maybe a small space heater. ironically i think a fridge cooling down would be more efficient than a space heater until it gets to equilibrium. anyways going to go with a 1000watt inverter just coz im not sure of the starting current for compressors.
If a refrigerator says it uses 478kwh per year, what is that a day? 1,309watts ? Is that correct? When I tested it with my meter it said at that moment it was using 2w and when I first plugged it in it jumped to 172w temporarily as it started back up, its a 2020 model, what are your thoughts please? And thanks for this video
478kwh per year is the average energy consumption of your model refrigerator which would depend on how often you open the unit, what you place inside the unit that needs cooled (or is colder then your unit example dry ice) and the ambient temperature of the room the unit is installed in. Assuming the average 478,000 watts per year, you are correct. It uses 1,309 watts per day. The unit cycles on and off to keep the internal temperature within a set temperature perimeter. So if the compressor and fan use 172 watts while running, your unit will cycle on and off a dozen times or so a day as just an example. More often if you open it. It will intermittently run for a total of 7.61 hours per day at the for mentioned 172 watts. 7.61 hours x 172 watts = 1,309 wH 1.309 kWh per day in a year 1.309 x 365 = 478KWH per year
Dave on a new 24 cubic foot Samsung french door with freezer at bottom rated at about $74.00 per year to run what percent of the wattage is for running the freezer section?
+dontrell iommi I know this is a very old question, lol. But no. 90 watts X 24 hours = 2160 watts, or 2.160 hWh a day. 8 cents X 2.160 kWh @ 8 cents per kWh = 17.28 cents a day.
8 years ago and still the best video

Very helpful and concise. Thanks!

Can you please tell us how much in cents or dollars a day/month?
That's funny I have the same fridge as the first one. My power went out and I was trying to figure if my car power inverter would power it. Looks like it will. Thanks
Need 3x the power to start it.

7.61 hours x 172 watts = 1,309 wH
1.309 kWh per day in a year
1.309 x 365 = 478KWH per year
Whatt does a 3.2 cu inch compack fridge use as far as watts i want to run mine of my solar grid
Do you see any problem adding a storage room pull string light off the same outlet in which a refrigerator is connected?
+bradley wenger Nope, the light will be fine running on the same circuit as the refrigerator.
Thanks for Watching!
Is 395kwh good for fridge?
will two fridges raise the light light bill?
My fridge uses 22 watts with the fan and compressor off. Is that normal?
Does it using 71 watts for one hour ?or for one minute
Dave on a new 24 cubic foot Samsung french door with freezer at bottom rated at about $74.00 per year to run what percent of the wattage is for running the freezer section?
Watts are power. Time is not part of the measurement. WattHrs then are energy which power x time.
Thank's Bill :) QC
How many watts inverter can I use with a refrigerator?
Can low voltage power mess up a fridge??
so my elec co says they charge 8 cents a kWh and my fridge is 182 watts, so that means that it burns 90 watts X 24 = 2160 watts X 8 = 1.72 a day?
+dontrell iommi I know this is a very old question, lol. But no. 90 watts X 24 hours = 2160 watts, or 2.160 hWh a day. 8 cents X 2.160 kWh @ 8 cents per kWh = 17.28 cents a day.
Your ac cannot work for 24hrs. AC, like a pressing iron is self-regulated
thanks bro
The amount of amps is something you should add.
Add to what?
Also, if you want to know amps, use the equation watts = volts x amps
so 200W/120VAC= ~1.7A
thanks
I think you need to take some time and go to inplix website to learn how to make it.
anyway to measure what your entire house is using with one of those meters
Alpha Bits & Bytes Gaming Lounge Read your main house meter then read next day and deduct first reading?
All wattage is rated in watts per hour.
