BASEUS

BASEUS 9V 500mA AC Adapter 5.5x2.1mm Tip Negative

SKU CH-B4G0-FZ3YB

A 9 V DC power supply delivering 500 mA through a 5.5 × 2.1 mm tip-negative barrel plug for guitar effect pedals

  • TypeAC Adapters
  • Delivers stable 9 V DC power for effect pedals
  • Wide 100-240 V AC input works worldwide
  • Tip-negative 5.5×2.1 mm barrel fits most pedals
  • 5 m cord gives flexible stage placement
  • IC chip design reduces noise and interference

Purpose and compatibility

This BASEUS 9V 500mA AC adapter is built for guitarists who need a reliable power source for tip-negative effect pedals. It accepts AC 100-240V 50-60Hz input and delivers a steady 9V DC 500mA 4.5W output through a 5.5 x 2.1 mm barrel connector.

Thermals noise and power

The adapter draws 0.6A at the wall and supplies 4.5W to the pedal, keeping power consumption low during practice or performance. A precise plug-in IC chip and premium PVC with low-impedance pure copper wiring provide anti-interference and noise reduction for a quiet signal chain.

Upgrade context

This unit replaces a lost or noisy original supply for any 9V tip-negative pedal that matches the 500mA current requirement and barrel size. It is not suited for pedals that demand higher current, centre-positive polarity, or a different voltage.

Questions about this item

How do I connect the 5.5 mm × 2.1 mm tip-negative plug to my pedal, and what polarity mistake should I avoid?

Plug the barrel into the pedal's 9 V DC jack with the centre pin negative; reversing polarity can damage the pedal's circuitry.

Will the 1.5 m cable or the AC plug need replacement under normal indoor use?

The fixed 1.5 m cable and integrated wall plug are rated for continuous 100-240 V 50-60 Hz operation; no scheduled replacement is required.

At what point does the 500 mA current limit become a constraint when chaining multiple pedals?

Total draw of all connected pedals must stay below 500 mA; exceeding it will cause voltage sag or shutdown.
