Power adapter specifications

This 12V 2.5A unit delivers 30W of continuous power for devices that require a regulated 12 volt supply. It accepts a universal 100-240V input at 0.8A across 50-60Hz, making it suitable for worldwide mains voltages. The barrel connector measures 5.5mm by 2.1mm, and a power cord is included with domestic purchases.

Suitable devices and limitations

The adapter suits any equipment rated for 12V 2.5A with a matching 5.5x2.1mm jack, such as certain routers, small monitors or external drive enclosures. Devices that draw more than 2.5A or require a different voltage cannot use this unit. Buyers who need a higher current rating or an alternative connector size should look at a different model.

Deciding specification

The fixed 12V 2.5A output combined with the 5.5x2.1mm barrel plug determines compatibility. Verify that the target device lists exactly 12V and a maximum draw of 2.5A or less, and that its power jack matches the 5.5mm outer and 2.1mm inner diameter.

Questions about this item

How can I confirm the NU30-4120250-I3 is delivering 12V 2.5A after connecting it?

Measure the output with a multimeter set to DC voltage; it should read 12 V under load, and the connected device should power on without shutting down.

Does the NU30-4120250-I3 include the AC power cord, or must I buy one separately?

The adapter ships with a power cord, though overseas purchases may exclude it. The barrel connector is 5.5 mm outer by 2.1 mm inner.

Should I choose this 30W model or a different wattage for a device rated 12V 2.5A?

Select this 30 W unit when your device requires 12 V at up to 2.5 A; a lower-wattage supply would not meet the current demand.
