Dell 12V 3A adapter purpose

This Dell 12V3A1T adapter converts 100-240V AC mains power to 12V DC at up to 3 amps for 36 watts maximum output. It suits devices such as LED strips, CCTV cameras, routers, external hard drives or monitors that draw 3 amps or less at 12 volts.

Capacity and headroom

The unit delivers 12 volts at a maximum of 3 amps, so any load up to 36 watts runs within its rating; a 2.5 amp or 2 amp device leaves headroom while a 3 amp load uses the full capacity. Continuous operation at the 3 amp limit is supported by the ETL-listed over-voltage, over-current, short-circuit and over-temperature protections.

Barrel connector limits

A 5.5 mm outer diameter barrel plug with 2.1 mm or 2.5 mm inner diameter fits the output, polarity centre-positive. The 6.2 ft AC cord and supplied female DC screw-terminal connector allow flexible placement indoors, but the adapter is not waterproof and must not be used outdoors.

Questions about this item

Will the 5.5 mm barrel connector on this 12 V 36 W adapter fit my existing 5.5×2.1 mm device jack?

Yes — the supplied DC plug is 5.5 mm outer diameter with an inner diameter range of 2.1–2.5 mm, so it mates with both 5.5×2.1 mm and 5.5×2.5 mm jacks.

How can I confirm the adapter is delivering a steady 12 V 3 A after I plug it in?

The unit is ETL, FCC, CE, RoHS and CCC listed and includes over-voltage, over-current, short-circuit and over-temperature protection; a stable 12 V DC output within the rated 36 W indicates correct operation.

What exactly ships in the box and is any extra cable or tip required?

The package contains one 12 V 3 A power supply with a 6.2 ft AC cord and one screw-terminal DC female connector; no additional cables or tips are needed for standard 5.5 mm barrel devices.
