BASEUS 12W Universal AC Adapter Reversible Polarity 3V-12V 1.2A 9 Tips

SKU CH-ZGN8-F7H0T

A reversible-polarity 12 W AC adapter with nine swappable tips covering 3 V to 12 V outputs up to 1.2 A for routers, speakers, cameras and other household electronics

  • TypeAC Adapters
  • Reversible polarity lets you match any device's power input
  • 12 W output covers 3 V to 12 V household electronics
  • Nine interchangeable tips fit routers, speakers, cameras and more
  • Single 1.2 A adapter replaces multiple original power supplies
  • Selectable voltage steps include 4.5 V and 7.5 V for precise matching

Universal 12W Multi-Voltage AC Adapter

This 12W universal AC adapter delivers selectable DC output from 3V to 12V at 1.2A maximum current. It includes nine interchangeable tips and a polarity-reversal key for centre-positive or centre-negative connections. The unit replaces multiple single-voltage power supplies for compatible household electronics.

Suitable for low-power DC devices up to 1200mA

Buyers powering routers, speakers, monitors, cameras, LED strips, keyboards or effect pedals within the 3V to 12V range will find the voltage selection and tip variety convenient. Devices requiring more than 1.2A, voltages above 12V, or sensitive RF equipment such as AM/FM radios should use a dedicated supply instead.

Reversible polarity with nine selectable tips

The adapter's defining feature is the physical polarity-reversal key combined with nine marked tips covering common barrel sizes. This single mechanism determines whether the unit can connect to a specific device without needing separate adapters for each polarity or connector type.

Questions about this item

Which devices can I power with the 3 V to 12 V output and 1.2 A rating?

The adapter supplies 3 V, 4.5 V, 5 V, 6 V, 7.5 V, 9 V or 12 V DC at up to 1200 mA, suitable for routers, speakers, monitors, cameras, smartphones, LED strips, keyboards and effect pedals that match those voltages.

Will the reversible polarity tips work with my existing centre-negative gear?

Yes, each of the nine included tips can be flipped to provide either centre-positive or centre-negative polarity, so older devices with either wiring convention are supported.

How do I confirm the adapter is delivering the correct voltage after I select a setting?

Set the voltage dial to the required value, attach the matching tip with the correct polarity orientation, then measure the output with a multimeter; it should read the chosen voltage (3 V, 4.5 V, 5 V, 6 V, 7.5 V, 9 V or 12 V) under load.
