Dell 1250 12 V 5 A 5.5×2.1 mm power adapter

Dell 1250 12 V 5 A power adapter

The Dell 1250 is a 60 W AC-DC power supply that delivers 12 V at up to 5 A through a 5.5×2.1 mm centre-positive barrel connector. It is intended for users who need a replacement or spare adapter for monitors, routers, projectors, CCTV cameras, speakers or webcams that specify a 12 V input not exceeding 5 A.

Build integration and cable reach

The unit accepts a worldwide 100-240 V AC input at 50/60 Hz, so it works on mains supplies in most regions without a separate voltage selector. A 6 ft (180 cm) DC cord provides enough length for typical desk or wall-mounted installations, and the male barrel plug mates directly with the device’s power jack. The adapter is rated for indoor use in ambient temperatures from 0 °C to 40 °C and should be kept dry.

Replacing lost or failed 12 V 5 A bricks

This adapter replaces an original 12 V supply rated up to 5 A, covering lower current draws such as 2 A, 2.5 A, 3 A, 3.5 A and 4 A automatically. The jump is worth it when the original brick is lost, damaged or shows signs of overheating, and the device’s label confirms a 12 V centre-positive barrel input within the 5 A limit. It is not suitable for phones, tablets, laptops or other precision electronics that require regulated USB-C or proprietary power profiles.
