Why Use a Power Strip or Extension Lead for Computers?

Modern setups often include multiple devices: a computer, monitor, speakers, printer, phone charger, external drives, and more. A high-quality power strip or extension lead:

  • Expands the number of accessible outlets

  • Provides surge protection for sensitive equipment

  • Reduces clutter and improves cable management

  • Offers built-in USB charging ports for phones and tablets

  • Enhances safety with overload protection and switched outlets

💡 Standard extension leads are NOT the same as surge protectors. For sensitive electronics like computers, always choose a surge-protected power strip.

FAQ: Computer Power Strips & Extension Leads

What’s the difference between a power strip and an extension lead?
The terms are often used interchangeably, but a power strip typically refers to a block of multiple sockets, while an extension lead refers to a longer cable that extends your power reach. Many products combine both.

Do all power strips offer surge protection?
No, only surge-protected models do. Look for a joule rating and surge indicator light to confirm protection is included.

How many amps can I run through one power strip?
Most UK extension leads are rated for 13 amps or 3250 watts total. Never exceed this or plug high-power devices like kettles into the same strip as your computer.

Is it safe to plug a power strip into another power strip?
No. This is called daisy-chaining, and it’s a serious fire hazard. Always plug extension leads directly into a wall socket.

Are USB ports on extension leads safe for phones and tablets?
Yes, as long as they meet modern charging standards. Look for 2.4A output per port or USB-C PD (Power Delivery) for devices like iPads and modern smartphones.

How long should an extension lead be?
Choose the shortest length that works for your setup; long cables can tangle and create trip hazards. Common sizes are 1m, 2m, 3m, and 5m.

When should I replace a power strip?
Replace if you notice frayed cables, loose sockets, worn switches, or if the surge protection indicator goes out.
