9V 2A AC adapter with US plug

This BASEUS power supply converts 100-240V AC input at 50/60Hz to a regulated 9V DC output at up to 2A, delivering a maximum of 18W. It features a 5.5mm x 2.5mm barrel connector that is also compatible with 5.5mm x 2.1mm ports, wired centre-positive. The unit includes over-voltage, over-current, short-circuit, overload and surge protection in a fanless, silent design. A 1.0m cable provides flexible placement for desktop or wall-mounted devices.

Suits 9V devices under 18W; not for higher loads

The adapter targets routers, LED lamps, IP cameras, speakers, handheld vacuums, lighted mirrors, juicers, humidifiers, security monitors, air purifiers and similar 9V equipment drawing less than 18W. Buyers needing more than 2A of current or a voltage other than 9V should look at alternative power supplies. The fixed US plug means users outside North America require a separate travel adapter. No battery or portable operation is offered.

5.5mm x 2.5mm centre-positive barrel plug

The output connector measures 5.5mm outer diameter by 2.5mm inner diameter and accepts 5.5mm x 2.1mm plugs as well, with the inside contact carrying positive polarity. This single physical interface determines compatibility with the target device, so verifying the device's jack size and polarity before purchase is essential. The 1.0m cable length is fixed and cannot be extended without an additional coupler.

Questions about this item

What devices can I power with the 9 V 2 A output and 5.5 × 2.5 mm plug?

The adapter supplies up to 18 W to any 9 V device drawing 2 A or less — routers, LED lamps, IP cameras, small vacuums, humidifiers and similar gear — using the centre-positive 5.5 mm × 2.5 mm barrel connector.

Will the 100-240 V 50/60 Hz input work on the older wiring in my house?

Yes, the wide-range input accepts any mains voltage from 100 V to 240 V at either 50 Hz or 60 Hz, so it runs safely on legacy household circuits without a separate transformer.

How do I confirm the unit is delivering the rated 9 V 2 A after I plug it in?

Measure the DC plug with a multimeter set to DC volts; you should read 9 V with the centre pin positive and the barrel negative while the adapter is connected to a load under 18 W.
