BASEUS 9V 3A 27W AC Adapter with 6 Tips and Polarity Cable

SKU CH-HP09-2CAX9

A 27W universal 9V AC adapter with six interchangeable tips and a reverse-polarity cable for centre-negative devices

  • TypeAC Adapters
  • Delivers 27 W output for reliable 9 V device operation
  • Accepts 100 V to 240 V input for worldwide mains compatibility
  • Includes six interchangeable tips plus 5.5 mm × 2.1 mm plug for broad device fit
  • Supplied polarity-reverse cable powers centre-negative gear such as guitar pedals
  • Built-in short-circuit, over-voltage, over-current, over-temperature and surge protection safeguards connected equipment

Universal 9 V 3 A power supply

This 27 W AC adapter delivers a regulated 9 V output at up to 3 A and automatically supports any device that draws 300 mA to 3000 mA. It accepts mains voltages from 100 V to 240 V at 50 Hz or 60 Hz, making it suitable for worldwide use. The unit is designed for 9 V electronics such as speakers, keyboards, guitar pedals, Arduino boards, security cameras, routers and similar household devices.

Steady output with full protection

Under continuous load the adapter maintains a stable 9 V rail while its built-in safeguards — short-circuit, over-current, over-voltage, over-heating and surge protection — interrupt power before components can be damaged. The 0.5 A input rating at 100–240 V ensures the supply runs cool during extended sessions, so connected equipment receives clean power without voltage sag or thermal throttling.

Six swappable tips and polarity cable

A 5.5 × 2.1 mm barrel plug ships with six interchangeable tips, covering the majority of 9 V device connectors encountered in daily use. An included reverse-polarity cable converts the standard centre-positive pinout to centre-negative, allowing immediate compatibility with guitar pedals and other centre-negative gear. The fixed cable and compact brick format keep the setup tidy on a desk, pedalboard or bench.

Questions about this item

How much heat or noise does the 27 W adapter produce when left plugged in all day?

The unit has no fan and runs silently; with built-in overheating protection it stays cool enough for continuous use on a desk or pedalboard.

Which cables or tips must I already own to connect this 5.5 × 2.1 mm plug to my device?

Six interchangeable barrel tips and a polarity-reverse cable are included, so no extra connectors are needed for most 9 V devices.

Will the 9 V 3 A output safely power my older 9 V gear that draws only 200 mA or 600 mA?

Yes — the adapter automatically supplies up to 3 A and is compatible with any 9 V load drawing 3000 mA or less, including low-current legacy equipment.
