Universal 20 V 3 A Power Supply

This BASEUS adapter converts 100–240 V AC mains power into a regulated 20 V DC output rated at 3 A. It ships with four interchangeable barrel tips plus a 5.5 × 2.5 mm plug that also accepts 2.1 mm jacks. The unit is designed for direct equipment power rather than battery charging.

Suitable for fixed-voltage 20 V devices up to 3 A

Routers, monitors, audio gear and other hardware that expects a steady 20 V supply within the 0.5 A to 3 A range will operate correctly. The adapter cannot charge laptops, phones or speakers that require a charging protocol or a different voltage. Buyers needing adjustable output or USB Power Delivery should look elsewhere.

Output fixed at 20 V 3 A with 5.5 × 2.5 mm connector

The single decisive specification is the constant 20 V 3 A rating combined with the centre-positive 5.5 × 2.5 mm barrel (compatible with 2.1 mm). If the target device demands a different voltage, a higher current or a proprietary charging handshake, this supply will not work.

Questions about this item

What comes in the box and do I need to buy any extra cables?

The package includes one 20V 3A AC to DC charger and five interchangeable DC jacks covering 5.5x2.5mm, 5.5x2.1mm, 4.8x1.7mm, 6.0x3.0mm and 6.0x4.4mm sizes. No extra cables are required for connection.

How do I choose the right tip for my device?

Check your device's DC jack dimensions and required current. The adapter auto-adjusts between 0.5A and 3A at 20V, so select the tip that physically matches your port — 5.5x2.5mm, 5.5x2.1mm, 4.8x1.7mm, 6.0x3.0mm or 6.0x4.4mm.

What does the 20V 3A rating mean when I plug this into my equipment?

It delivers a fixed 20 volts and will supply up to 3 amps, automatically matching any device that draws between 0.5A and 3A at 20V. It is designed for direct power applications such as routers, not for charging laptop batteries or phones.
