  • Isolated 10-output design prevents ground-loop hum across the board
  • Built-in short-circuit, overcurrent, overload and overvoltage protection safeguards gear
  • Universal 100-240 V AC input with 50/60 Hz readiness for worldwide use
  • 14 m cable with 5.5 × 2.1 mm centre-negative plug fits most pedals

Power Supply for Pedal Boards

The Kenuco 18V DC 1A adapter delivers isolated power to guitar pedals and effects units. It accepts AC 100-240V input at 50/60Hz for worldwide compatibility. The 5.5 x 2.1mm DC connector uses centre-negative polarity. This unit suits players needing a single 18V source for their board.

Steady Output Under Load

The supply maintains a regulated 18V DC at up to 1A (1000mA) continuous current. Built-in short-circuit, overcurrent, overload and overvoltage protection engage automatically during sustained draw. The 24W rating supports consistent operation without voltage sag. It is not for setups requiring multiple isolated outputs or higher total current.

Thermals and Noise in Use

Passive convection cooling keeps the adapter silent during normal operation. The 1.14m cable length allows flexible placement away from audio paths. No fan noise is introduced into the signal chain. The unit runs warm but within safe limits at full 1A load.

Questions about this item

How hot or noisy does the 18V 1A adapter get when powering a pedal board all day?

The unit has no fan and relies on passive cooling; with short-circuit, overcurrent, overload and over-voltage protection it runs silently and stays cool during continuous use.

What must I already own to use this 5.5 × 2.1 mm centre-negative plug?

You need pedals or a board that accept an 18V DC centre-negative 5.5 × 2.1 mm barrel connector and draw no more than 1A each.

Will this 100-240V 50/60Hz supply work safely with my vintage 9V-only pedals?

No — the fixed 18V output exceeds what 9V pedals expect and could damage them; use only with pedals rated for 18V DC.
