Dell MYT-1203BK 36W adapter
The Dell MYT-1203BK is a 12 V 3 A AC/DC power adapter delivering up to 36 W. It suits devices such as LED strip lights, CCTV cameras, speakers, routers or similar 12 V equipment that draws 3 A or less.
Replaces worn or lost 12 V barrel supplies
This unit replaces an original or failed 12 V adapter with a 5.5 mm × 2.5 mm centre-positive barrel plug. The jump is worth it when the existing supply cannot deliver the full 3 A, shows voltage drift, or has a damaged cable.
Check connector, polarity and load before ordering
Verify that the device uses a 5.5 mm × 2.5 mm DC jack with inner positive and outer negative polarity. Confirm the equipment’s maximum draw does not exceed 3 A at 12 V. Ensure the input voltage range of 100–240 V AC matches the local mains supply.

Questions about this item
Does the 5.5 mm x 2.5 mm barrel connector fit my device's DC jack?
The adapter uses a 5.5 mm outer and 2.5 mm inner diameter barrel plug with inner-positive polarity; verify your device's jack matches those dimensions before connecting.
What is the correct way to plug it in so the polarity is not reversed?
Connect the AC cord to a 100-240 V 50/60 Hz outlet, then insert the barrel plug fully into the device's DC jack ensuring the centre pin carries positive voltage.
When should I replace the 36 W adapter or its 150 cm cable?
Replace the unit if the cable sheath shows cracks, the barrel plug becomes loose or intermittent, or the adapter overheats or shuts down under normal load.
