Mini refrigerator wattage?
I'm trying to determine how much wattage a minirefrigerator uses. Here's the specific model I'm interested I'd like to get: http://products.geappliances.com/App...SCS&SITEID=GEA
Unfortunately, GE, and most other manufacturers, don't list this information. They do show their energy guide however, which states that this product consumes 345 kWh a year. Advertisement

Guesstimate....
I have seen current draw of a full size refrigerators ballparked for calculations at 425 watts which would be 3.7 amps, for compressor start up add 70%, so another 300 watts for a total of 725 watts max or 6.3 amps. A smaller unit would obviously be some amount less but a compressor is a compressor so I imagine it could still be 5 amps max. If you can find one in a store you can get better info off the tag on the back too. Advertisement

Thanks, I did. It's 145W, which is a lot lower than I expected.

KW/H = Watts x Hours/1000
so 345 = W x 8640/1000 so W x 8640 = 345 x 1000 so W = 345,000 / 8640 W = 39.9305 Watts which by the way would not be possible for a minifridge running on mains power as the low wattage of 39 watts is unheard of and impossibile. unless it's mayby a 12volt minature one capable of holdin a single beer I know its an old thread but I hope it heps somebody another formula to find Power (P) measured in watts is P = V x I meaning power in watts = Volts x Amps Or another to find KW/h is..... V x I x Hours /60 Last edited by technoir1; 10202008 at 05:18 AM.

Sort of the same point as the poster above me, but you've also assumed constant usage.
I don't know the formula they use for those energy star ratings but I'm sure it's not full load consumption for 8640 hours (every minute of an entire year). I've also gone looking for mini fridge current draw  trying to decide if I want to put a dedicated circuit in for a mini fridge. I came up empty too. I'm glad someone in this thread had a number (145w)...definately helps my decision.

TRY THIS, AS A START...
http://www.ftc.gov/bcp/conline/edcam...ndef_brand.pdf ITS MY UNDERSTANDING THAT TO GET YOUR CONSUMPTION...PER THE GOVT INFO PROVIDED YOU TAKE THE ANNUAL POWER CONSUMPTION DIVIDE BY 365 THEN TAKE THAT 'RESULT' AND DIVIDE BY 24... FOR A REAL SIMPLE, BALL PARK, HOURLY POWER CONSUMPTION FROM A KWA NUMBER. NOW, YOU CAN COMPLICATE THIS WITH ALL SORTS OF BELLS, WHISTLES AND ASSORTED SITUATIONS HAPPENING, BUT IT IS THE 'GOV'T.S' NUMBERS... AND WE ALL KNOW WE CAN TRUST THEM TO RUN THINGS... LIKE MINI FRIDGES! IVE FOUND INFO ON USING CHEST FREEZERS AS FRIDGES...PRETTY SIMPLE! ALOHA Advertisement
