SKU CH-XH9D-R98KT MPN F12US1200100A

A 12V 1.0A power adapter with a 5.5x2.1mm connector, accepting 100-240V input at 50-60Hz

  • Worldwide voltage input 100-240V 50-60Hz
  • Steady 12V 1.0A output for reliable power
  • 5x2.1mm barrel fits compatible devices
  • Built-in protection against short circuit and overheat
  • Genuine OEM adapter tested for full function

Power adapter 12 V 1.0 A

This AC-to-DC adapter delivers a regulated 12 V output at 1.0 A through a 5.5 mm by 2.1 mm barrel connector. It suits routers, set-top boxes, LED strips and similar low-power 12 V equipment. The unit accepts 100-240 V input at 50-60 Hz for worldwide mains compatibility.

Replaces lost or faulty 12 V 1.0 A units

Swap this in when the original supply is missing, damaged or no longer holds regulation under load. The change is worthwhile if the device requires exactly 12 V and draws no more than 1.0 A; higher-current gear will overload the adapter.

Plug-in barrel connection

Installation is a simple matter of matching the 5.5 mm by 2.1 mm plug to the device jack and connecting the IEC mains lead. The most common issue is polarity mismatch — confirm the centre-positive symbol on the hardware before powering up.
