How many gadgets are safe to run on an extension board? Understand the math
- •The safety of running gadgets on an extension board depends on its capacity and total power consumption.
- •Most common household extension boards are designed to handle loads of up to 1000 to 1500 watts.
- •Low-power devices like mobile chargers, laptops, and televisions can generally be run simultaneously.
- •High-power appliances like geysers, room heaters, and irons should be plugged directly into wall sockets.
- •Overloading an extension board causes wires to heat up rapidly, increasing the risk of short circuits and fires.
Key Questions Answered
Most common household extension boards are designed to safely handle a power load of up to 1,000 to 1,500 watts. However, users should always check the specific rating listed on the board before plugging in multiple devices.
High-power appliances such as room heaters, geysers, electric kettles, microwaves, washing machines, refrigerators, and irons should be avoided. For example, a geyser can consume up to 2,000 watts and an electric kettle uses about 1,500 watts, which can easily exceed an extension board's capacity.
An overload can cause wires to heat up rapidly and damage their protective insulation, leading to short circuits or fires. Warning signs include the board or wires feeling hot, a burning smell, or discoloration around the plug area.
