7 Devices That Secretly Drain More Electricity Than an Air Conditioner—Unplug Them to Avoid Skyrocketing Bills!

Certain household appliances continue to consume electricity even when not in use. To save on your electricity bill, make sure to unplug these devices after use!

 

 

1. Induction Cooker

Induction cookers are a staple in many households due to their convenience and safety compared to traditional gas stoves. Compact single-burner models are commonly used for hotpot meals, while larger two- or three-burner versions are permanently installed in kitchens.

• Electricity consumption:
  • A single-burner induction cooker used for about 3 hours daily can consume 85-95 kWh per month.
  • A double-burner model can use up to 170-190 kWh monthly, depending on its power and frequency of use.

Tip: Unplug the cooker after use to reduce standby power consumption.

2. Water Heater

A water heater is essential, especially in winter, and is widely used in northern regions with colder climates. A 30-liter water heater, common in households with 2-4 people, consumes a significant amount of electricity.

• Electricity consumption:
  • If used for about 1 hour daily, it can consume 70-80 kWh per month.
  • If left on continuously, it can use up to 230-340 kWh monthly.

Tip: Only turn it on before use and unplug it afterward to prevent unnecessary energy waste.

3. Electric Kettle

Electric kettles are a must-have in many Vietnamese households for boiling water daily. Large kettles (4-6 liters) continuously boil and maintain water temperature, consuming more electricity than expected.

• Electricity consumption:
  • Power ranges from 700W to 1,200W, depending on capacity and manufacturer.
  • If used continuously to heat 6-8 liters daily, it can consume 40-100 kWh per month.

Tip: Avoid leaving it plugged in all day—only turn it on when needed.

4. Clothes Dryer

During humid seasons, especially in spring and winter in northern Vietnam, clothes dryers become essential for keeping laundry fresh. However, they are one of the most power-hungry appliances in the home.

• Electricity consumption:
  • A standard 8kg dryer (vented or condenser type) used 1-2 hours daily can consume 75-140 kWh per month.
  • More energy-efficient heat pump dryers use significantly less power.

Tip: If possible, air-dry clothes to cut down on electricity usage.

5. Refrigerator

Refrigerators run 24/7, making them one of the most power-consuming appliances in any household.

• Electricity consumption:
  • Mini fridges (under 100 liters) use 10-15 kWh per month.
  • Medium-sized refrigerators (around 300 liters) consume 30-45 kWh per month.
  • Large refrigerators (over 400 liters) can use 50-75 kWh monthly.

Tip: Regularly clean the coils and set the fridge at optimal temperatures (3-5°C for the fridge, -18°C for the freezer) to reduce power consumption.

6. Television

Most people turn off their TV using the remote, but this doesn’t completely power it down—it still consumes electricity in standby mode.

• Standby power can significantly increase monthly electricity bills.
• Leaving the TV plugged in also increases the risk of electrical fires in case of a short circuit.

Tip: Always unplug the TV when not in use to cut down on unnecessary energy usage and fire hazards.

Final Advice

To avoid high electricity bills, unplug these devices after use. Even when turned off, they can still consume power in standby mode—leading to wasted energy and higher costs!
