Do Mini Fridges Use a Lot of Electricity?

mini fridge use electricity

Do mini-fridges use a lot of electricity? Refrigerators are no longer the massive energy wasters they previously were, thanks to the development of more energy-efficient versions. Still, a sizable amount of your electricity cost is attributed to their power usage. You might be a good candidate for a tiny fridge if you live alone and don't frequently stock your refrigerator with fresh food. Their energy usage is still a major consideration when deciding whether or not to purchase them, though. In any case, how much electricity does a compact fridge consume? Let's investigate and look for ways to reduce its electrical expenses while we're at it.

What is a Mini Fridge?

In terms of keeping your food fresh and your drinks cold, a micro-fridge is comparable to a standard refrigerator. Also, the features and functionalities of the two versions are nearly identical. A micro refrigerator, on the other hand, is made to fit in small places, unlike a standard refrigerator. 

Because of this characteristic, many people who live in small flats or dorms choose it. The smaller model's energy usage is another factor that makes people choose it. Generally speaking, a small refrigerator uses less electricity than a large refrigerator.

Average Energy Consumption

A fridge is a need for any home. However, for convenience, some homes decide to install a tiny fridge. Because power is costly, the amount of electricity mini-fridges use is frequently a determining factor when determining whether the convenience of owning a small refrigerator justifies the cost of electricity usage.

So, what is the electrical consumption of a tiny fridge? 

Mini fridge energy consumption varies based on a number of factors. The number of kilowatt hours they use is influenced by factors such as their age, model, size, energy efficiency, and surrounding ambient temperature.

The sizes of mini refrigerators typically range from 1.7 to 4.4 cubic feet. Energy Star estimates that mini-fridges of this size consume between 233 and 310 kWh. In the meantime, tests conducted by Consumer Reports show that an energy-efficient 4.4 cubic foot mini fridge has an annual energy cost of $27. 

Do Mini Fridges Use A lot of Electricity? 

\You might be curious about how much a compact refrigerator will contribute to your home's annual electricity use, given the escalating cost of electricity. Thankfully, there's a simple learning method. You must ascertain the wattage, or the number of watts required for small fridges to function, in order to compute the amount of electricity they consume.

Look for the small refrigerator's volts and amps on the sticker inside the refrigerator if you are still looking for the information on the equipment or manual. To determine the machine's wattage, multiply these figures.

You can calculate your micro fridge's power consumption once you know its wattage. Here's how you can accomplish it.

  • The amount of hours the mini fridge runs in a day can be found by multiplying its running wattage by 24.
  • The watts (W) can be converted to kilowatts (kW) by dividing the value by 1,000.
  • Examine your electricity bill to find the cost per kilowatt-hour (kWh).
  • To calculate how much it will cost to operate your mini fridge each day, multiply the kW by the kWh rate.
  • To find the monthly energy expenditures for your tiny fridge, multiply the daily costs by thirty.
  • Multiplying the monthly expenses by 12 will get the annual energy use.

It is an illustration of how to calculate the energy consumption of a small refrigerator. Assume the local electricity tariff is $0.10 per kilowatt-hour, and the tiny refrigerator has a wattage of 250.

  • 250 watts x 24 hours = 6,000 watts (W)
  • 6,000 ÷ 1,000 = 6 kilowatt hours (kWh)
  • 6 kWh x $0.10 per kWh = $0.60 per day
  • 0.60 x 30 = $18 per month
  • 18 x 12 = $216 a year

Factors Affecting the Power Consumption of Refrigerators

Refrigerator energy consumption varies, with smaller fridges using less energy than full-size ones. Daily energy usage depends on the watts required to run the appliance.

  • Usage:

How you use your refrigerator impacts energy consumption. Overloading or neglecting gaskets hinders airflow, forcing the compressor to overwork. An empty fridge also challenges efficiency, as the compressor compensates for lost, cold air, increasing energy consumption.

  • Door Opening Frequency:
  • Regularly opening the Door increases power consumption, compelling the compressor to work harder and raising energy usage by about 7 percent.

  • Fridge Model:
  • Fridge configuration affects cooling and power consumption. Bottom freezers use 16 percent less energy than side-by-side models. Manual defrost versions consume half the energy, while models with anti-sweat heaters may use 5 to 10 percent more power.

  • Size:
  • Larger fridges consume more electricity, leading to higher bills. Mini fridges use 233-310 kWh, while full-size ones consume 404-613 kWh.

  • Location:
  • Installation in the coolest part of the room enhances efficiency. Temperatures below 10 degrees Celsius may affect proper functioning.

  • Season:
  • Models may use more energy in summer due to higher temperatures. Cold weather tends to decrease power consumption.

  • Settings:
  • Adjusting thermostat settings impacts operating costs. Higher settings lead to increased power usage, with a potential 25 percent higher consumption for fridges set 10 degrees colder.

    How to Decrease Your Mini Fridge’s Energy Use?

    Reducing your mini fridge's energy consumption can save you money on electricity costs. Follow these tips:

    Keep the Door Closed: Limiting the time the Door is open prevents cold air loss and reduces the compressor's workload, saving energy.

    Choose Energy Star-certified: Opt for appliances with an Energy Star rating, as they are 9-15 percent more energy-efficient than non-certified models, leading to potential long-term savings.

    Keep Coils Clean: Dirty coils hinder the fridge's cooling efficiency, potentially increasing energy consumption by up to 83 percent. Regular cleaning not only lowers energy use but also extends the appliance's lifespan.

    Optimal Placement: Avoid placing the fridge in warm areas, such as near ovens or radiators, as it forces the appliance to work harder to maintain the desired temperature, increasing energy usage and expenses.

    Ensure Good Ventilation: Adequate ventilation is crucial to prevent overheating and overworking of the motor, leading to higher energy consumption. Maintain at least a 5-centimeter space around the back, top, and sides of the fridge for proper air circulation.

    Use Timer Switches: Implement timer switches to control the fridge's operation based on your settings. While not turning off the refrigerator completely, using a power-saving mode during low usage times can reduce energy consumption.

    Adjust Temperature Settings: Set optimal temperature ranges (between 5-18 degrees Celsius) for both the fridge and freezer to ensure food freshness without unnecessary energy consumption. Avoid excessively low temperatures that drive up power usage.
