Buying cheap extension boxes from the market might save you some money, but it puts your family’s safety at risk. Low-cost devices use poor-quality wires, weak insulation, and lack proper safety features. For example, a quality extension box will have a safety system like surge protection, which protects your devices during voltage spikes. Cheap boxes won’t have this. This can cause electrical leaks, short circuits, and easily lead to fires. It’s very important to buy products with a BIS quality mark.
