Dell AL12V1A 12V 1A power adapter
The Dell AL12V1A is a 12W AC-to-DC adapter that converts 100-240V mains input to a regulated 12V DC output at up to 1A. It is intended for installers and hobbyists powering low-draw 12V equipment such as LED strip lights, CCTV cameras, DVRs, NVRs, routers or small audio devices. The unit includes safety protections against overload, over-voltage, over-temperature and short-circuit conditions.
5.5mm x 2.1-2.5mm centre-positive barrel connector
The decisive specification is the DC plug: an outer diameter of 5.5mm with an inner diameter compatible with both 2.1mm and 2.5mm sockets, wired centre-positive. Before purchase, verify that the target device requires exactly 12V and draws no more than 1A, and that its jack matches this barrel size and polarity; the adapter cannot charge batteries and will not suit devices needing higher current or a different connector.
Female DC barrel terminal block included
A screw-terminal female barrel connector ships with the adapter, allowing bare wires to be secured without soldering. This speeds up installation for LED strips or security cameras that use flying leads, and it avoids the need for a separate connector kit. The 5-inch cable length keeps the adapter close to the device, so plan the routing accordingly.

Questions about this item
What does the 12 W rating mean when the adapter is powering a device?
It means the adapter can deliver up to 12 watts at a steady 12 V DC, so any connected load drawing 1 A or less will receive stable power without voltage droop.
What input voltage range does the AC side accept and what does that limit?
The adapter accepts 100–240 V AC at 50/60 Hz, so it works on mains worldwide without a separate voltage selector.
What physical clearance does the 5.5 × 2.5 mm barrel plug need to fit?
The plug has a 5.5 mm outer diameter and a 2.1–2.5 mm inner diameter with centre-positive polarity, matching the common CCTV and LED strip jack size.
