CRU DataPort MJ-1 USB Mouse Jiggler for Screen Saver Prevention

The CRU 30200-0100-0011 is a small USB device that quietly moves your mouse pointer just enough to convince any computer that someone is still at the keyboard. By simulating gentle activity, it stops screen savers, sleep timers, and auto-logout dialogs without needing software, drivers, or administrative rights.

Because everything happens the moment you plug it into a USB Type A port, the Mouse Jiggler is a handy tool for several situations. Presenters can keep slides visible during meetings, trainers can prevent classroom PCs from dimming, and IT staff can run lengthy installs or remote sessions without losing the connection. Forensic specialists and security auditors appreciate that the system never locks or times out while evidence is being collected. Even everyday users who queue large downloads or stream long videos can avoid constant wake-ups and password reentries.

Portability is built in. The device is roughly the size of a car key, fits any pocket or laptop bag, and draws power directly from the host computer, so no cable or adapter is required. Universal operating system support covers Windows, macOS, and Linux, and the unit meets FCC, CE, and RoHS standards. CRU backs the Mouse Jiggler with a two-year limited warranty for extra peace of mind.
