Dell MT-1201 12W AC Adapter
The Dell MT-1201 is a compact AC adapter that converts 100-240V AC input into a regulated 12V DC output rated at 1A and 12W. It terminates in a 5.5mm by 2.5mm barrel connector with centre-positive polarity and includes a short 5-inch cable tail for direct device connection.
Suitable for low-draw 12V equipment
This unit powers routers, small speakers, fans, Arduino boards and 12V LED strips such as 2835, 5050 or WS2811 types that draw less than 1000mA. It will not support devices requiring higher current, such as 2A CCTV cameras or longer LED runs needing 24W, so buyers needing more power should look at a higher-wattage supply.
Bundled 10ft extension cord adds reach
A 10-foot DC extension cable with the same 5.5mm by 2.5mm or 2.1mm barrel plug is included, letting the adapter sit near a wall outlet while the device operates up to 3 metres away. The blue indicator light on the adapter body confirms operation without extra tools.

Questions about this item
What cable length must I already have if I need the adapter to reach a device further than 5 in?
The unit ships with a 5 in cable, so any additional reach requires a separate extension cord you provide.
Will the 5.5 mm × 2.5 mm barrel connector fit the 5.5 mm × 2.1 mm jack on my older router?
The plug is a fixed 5.5 mm × 2.5 mm barrel; it will not seat securely in a 2.1 mm inner-diameter jack.
How do I confirm the MT-1201 is delivering 12 V 1 A after I plug it in?
A blue indicator light on the adapter illuminates when the unit is powered and operating.
