BASEUS 12V 3A AC Adapter 11 Plugs 36W

SKU CH-DA9J-HTXBD

A 12V 3A 36W regulated switching power supply with 11 interchangeable DC plugs and built-in short circuit, over-current, over-voltage and over-temperature protection

  • TypeAC Adapters
  • 12 V 3 A regulated output powers 11 interchangeable tips
  • 3 ft cable gives extra reach for desk or travel use
  • 100–240 V input works worldwide without a voltage converter
  • 5 × 2.1 mm barrel with 2.5 mm compatibility fits many devices
  • circuit, over-current, over-voltage and over-temperature protection built in

Power output and compatibility

This 12V 3A AC adapter delivers a regulated 36W output and includes 11 interchangeable DC plugs. It automatically identifies the required current from 100mA up to 3000mA, covering devices rated at 500mA, 600mA, 700mA, 800mA, 900mA, 1000mA, 1500mA, 2000mA, 2500mA and 3000mA. The barrel jack measures 5.5mm by 2.1mm and accepts 2.5mm centre-positive tips.

Build integration and cable reach

The unit accepts a universal 100V-240V 50/60Hz input, so it works on mains supplies worldwide without a separate voltage selector. A 3.3 foot (100cm) cable provides extra reach for desk or bench setups where the socket is further away. The compact switching design keeps the brick small enough to sit on a power strip without blocking adjacent outlets.

Sustained-load protection

Built-in safeguards monitor for short circuit, over-current, over-voltage and over-temperature conditions during continuous operation. If any limit is exceeded the adapter shuts down to protect both itself and the connected equipment. It is not suitable for devices that require more than 3A at 12V or that use a different output voltage.

Questions about this item

How much continuous power can the 12 V 3 A adapter deliver before its over-temperature protection engages?

The unit is rated for 36 W continuous output; its built-in over-temperature protection will activate if that limit is exceeded for a prolonged period.

Does the power supply run silently and stay cool during all-day operation?

It has no fan and relies on passive cooling; the housing warms under full 36 W load but remains within safe limits thanks to over-temperature protection.

Which devices can I connect using the included 11 interchangeable DC plugs?

The 5.5 mm × 2.1 mm barrel jack fits centre-positive equipment drawing from 100 mA up to 3000 mA at 12 V, covering the listed current steps.
