Overview
A compact 3-outlet surge protector that plugs directly into the wall, rated for 660 joules with diagnostic LEDs that show grounding and protection status. Built for travel and tight spaces rather than a full power strip's worth of devices.
At 2.5 inches tall and 3.8 inches wide it sits flush enough to avoid blocking neighboring outlets on a standard wall plate, which is the main reason to pick this over a full-size strip. Eaton backs it with a 15 amp breaker that permanently cuts power if the surge protection itself fails.
- 3 outlets, 660 joule surge rating
- Diagnostic green/red LEDs for protection status
- UL Listed and UL 1449 certified
- 15 amp breaker with automatic shutoff
Who it's for
Suits travelers and anyone plugging a laptop, phone charger, or small appliance into an outlet that is crowded or hard to reach behind furniture. Not the right choice if you need to power more than three devices at once.
Pros and cons
- Small enough to avoid blocking other outlets
- Diagnostic LEDs flag wiring or protection faults
- Only 3 outlets, no USB ports
- Direct plug-in can still crowd stacked outlets
Performance notes
The 660 joule rating and sub-1 nanosecond response time handle typical surge events, with a 500/400/500 clamping voltage rating. UL 1449 certification and the automatic-shutoff breaker are the parts that matter for actual protection, not just the outlet count.
