When shopping for power solutions, you’ve probably seen terms like extension board and spike guard used interchangeably. But are they really the same thing? Spoiler: They’re not β€” and choosing the wrong one can put your devices at risk.

Let’s break it down in simple terms.


🧱 What is an Extension Board?

An extension board (or power strip) is a device that lets you plug multiple appliances into one wall socket. It’s essentially a multi-socket connector with or without a switch.

Best for:

  • Basic setups (lights, fans, chargers)
  • Places where you need more sockets

Limitations:

  • Usually no surge or voltage protection
  • Not ideal for sensitive electronics

πŸ›‘οΈ What is a Spike Guard?

A spike guard is a type of extension board that comes with built-in surge protection or a voltage suppressor. It guards your devices from sudden power spikes caused by lightning, power cuts, or fluctuations.

Best for:

  • Laptops, TVs, gaming consoles, routers
  • Areas with frequent voltage issues

Bonus:

  • Some spike guards come with USB ports, thermal cutoff, or circuit breakers.
