Key benefits
- Instant power control without unplugging: built-in 303 rocker switch lets you turn USB-powered devices on or off with a single press, so you can restart devices or cut power quickly without pulling cables.
- Prevents unnecessary wear and saves energy: switch off peripherals when not in use to reduce standby power draw and avoid repeatedly inserting and removing connectors.
- Compact and easy to install: short 0.3 m (30 cm) extension is ideal for tabletop use or tight spaces where a full-length cable would be cumbersome.
