Whether setting up a gaming den or stringing lights for gatherings this summer, choosing the right electrical gear matters. Power strips and surge protectors are power distribution devices that may look alike but serve different purposes — knowing when to use each helps keep your setup safe.
While both devices allow you to plug several appliances into one location, power strips simply provide more outlet spaces for a circuit, whereas surge protectors shield electronics from voltage spikes caused by lightning strikes, power outages or large appliances cycling on and off. Never plug a power strip or surge protector into each another — this can overload the circuit.
How to tell the difference between surge protectors and power strips:
- Most surge protectors have an information label providing their suppressed voltage rating, which measures the level of protection provided. Look for UL 1449 — this means it meets safety standards for surge protection.
- A surge protector contains components known as metal oxide varistors (MOVs). When voltage spikes above a safe level, the MOV absorbs the excess energy and diverts it safely to the ground, preventing damage to devices.
- Surge protectors’ MOVs degrade over time — especially after absorbing multiple surges. Experts recommend replacing surge protectors every three to five years or after a power surge. Some units have a light that signals when the protection is no longer active.
Surge protectors are essential for protecting sensitive or expensive electronics that could be damaged by voltage spikes, including:
- Home office setup: Prevents data loss and hardware damage during surges to a computer, monitor, printer or router.
- Entertainment center: For expensive devices sensitive to power fluctuations including TVs, gaming consoles, sound systems and streaming devices.
- At-home medical devices: This adds a layer of safety and reliability to oxygen concentrators and other home-use medical electronics
Power strips are best for basic power distribution when surge protection isn’t necessary, including:
- Kitchen Countertop Appliances: For powering kitchen staples that don’t typically need surge protection, such as a standard toaster, blender or coffee maker — though not all at once.
- Workshop or Garage Tools: For low-cost tools that are not sensitive electronics, like a drill or sander.
- Temporary Event Setups: For powering fans, lamps or audio equipment at a short-term party or event.
