Kenuco 12V AC Adapter 100-240V 1A 10 Jacks

SKU CH-EFS4-XR16G

Universal 12 V AC adapter with ten interchangeable DC plugs covers 100 mA to 1 A loads and accepts 100–240 V input

  • TypeAC Adapter
  • Universal fit with 10 interchangeable jacks included
  • Worldwide use on 100-240 V AC input
  • Safe charging via overcurrent, overvoltage and short-circuit protection
  • Regulated 12 V DC output up to 1 A max
  • Polarity-positive 5.5 mm × 2.5 mm plug fits 2.1 mm sockets

Universal 12V Adapter Kit

This 12V AC adapter accepts 100 to 240V input at 50 to 60Hz and delivers a regulated 12V DC output up to 1A. It includes ten interchangeable DC jacks covering current ratings from 100mA to 1000mA in 100mA steps. The kit targets owners of 12V DC devices such as routers, speakers or small electronics that require a replacement or spare power supply. It is not for devices needing more than 1A or a voltage other than 12V.

Compact Regulated Supply

The adapter measures 5.5mm by 2.5mm with 2.1mm applicability and uses a centre-positive polarity. Ten snap-on jack tips store on the cable for quick swapping without tools. CE and FCC listings confirm compliance with over-current, over-voltage and short-circuit protection. It is not for equipment with locking barrel connectors or proprietary multi-pin DC inputs.

1A Maximum Output

The single decisive specification is the 1A current ceiling at 12V. Any device drawing above 1000mA or requiring 12.6V maximum will exceed this adapter's rating. Buyers must match their device's label to 12V and 1000mA or less before purchase.

Questions about this item

What input voltage range does the AC adapter accept?

The adapter accepts AC 100 V to 240 V at 50 to 60 Hz, making it suitable for mains supplies worldwide.

What plug size and polarity does the 5.5 mm × 2.5 mm jack use?

The barrel plug is 5.5 mm outer diameter, 2.5 mm inner diameter, also compatible with 2.1 mm pins, and wired positive inside, negative outside.

How do you select the correct interchangeable jack for a device?

Match the device's required DC 12 V current (100 mA to 1000 mA) and plug size, then snap the corresponding jack onto the cable — forcing the wrong size can damage the connector.
