A basic power strip only adds outlets. A surge protector also contains components intended to absorb short voltage spikes. Look for clear safety certification from a recognized testing laboratory and instructions from an established manufacturer.
Check before buying
- Joule rating: A higher rating generally indicates more total surge energy capacity, but it is not the only quality measure.
- Protection indicator: Choose a model that tells you when surge protection is no longer active.
- Outlet spacing: Wide spacing helps larger power adapters fit without blocking neighboring outlets.
- Cord and plug: Match cord length and plug orientation to the room without creating a trip hazard.
Safety: Do not daisy-chain power strips, place them under rugs, or use them for high-load appliances unless the manufacturer explicitly permits it.
