30W 12V adapter for universal devices

This Lei Electronics 30W power adapter delivers 12V at 2.5A for devices that require a 5.5x2.5mm barrel connector. It suits routers, small monitors, external drives and similar 12V equipment. The unit accepts 100-240V input at 50-60Hz for worldwide use.

Compact build with fixed mains lead and detachable

The adapter body integrates the AC inlet and a captive DC cable ending in the 5.5x2.5mm plug. A standard IEC C7 figure-8 power cord is included for the mains side, so you can swap cable length or regional plug type. The fixed DC lead avoids loose connections at the device end.

Passive cooling keeps operation silent

With no fan, the adapter runs silently on a desk or behind equipment. Rated at 30W maximum, it draws up to 0.8A from the mains at full load. Protections against incorrect voltage, short circuit and internal overheating are built in.
