Overview
Tripp Lite built this surge suppressor to plug straight into the wall with no cord, adding extra outlets in a compact housing. Diagnostic LEDs warn about wiring or protection faults before connected equipment is damaged.
It turns one wall outlet into several and gives line noise and surge coverage in a travel-friendly size. A lifetime warranty and insurance back it, with insurance limited to three countries. There is no cord, so it occupies the wall outlet it plugs into.
Who it's for
Travelers and apartment dwellers who need a few protected outlets without cords. The listing names apartment, hotel, office, restaurant and TV uses. Home theater owners with high-end gear should look at a higher rating.
Pros and cons
- Direct plug-in, no cord to tangle
- Diagnostic LEDs show faults
- Lifetime limited warranty
- Compact and lightweight
- Modest surge energy rating
- Bulky adapters may block outlets
- Insurance limited by region
Performance notes
The joule rating shows how much surge energy the unit can absorb before its protection wears out, and it is a modest figure here. The diagnostic LEDs report wiring or protection faults, so a dark indicator is a cue to stop relying on it. Line noise filtering is mentioned without detail.
