Smart Keeper UCL03YL Smart Data Blocker Essential Basic Yellow Lockable USB-A Charge-Only Data Blocker without Key
Smart Keeper UCL03YL — Smart Data Blocker, Yellow
The Smart Keeper UCL03YL is the Smart Data Blocker in yellow, from the Basic series of Smart Keeper’s Essential line. It plugs into a USB-A port and locks there, and from then on the port only charges: Smart Keeper states it blocks all data connection while allowing the port to be used for charging. It is released only with a yellow Lock Key Basic (U03). In practice it lets visitors, staff or customers charge a phone from a PC, kiosk, display or charging point without any chance of files being copied to or from the device, and without anyone pulling the blocker out and using the port for data. The system is purely mechanical — no drivers, configuration or power — so it works the same on Windows, macOS, Linux, thin clients and embedded devices.
