Dell AL-1230 12V 36W Adapter
The Dell AL-1230 is a 12V 3A desktop power adapter rated at 36 watts. It supplies regulated DC power to monitors, routers, LED strips and similar low-power 12V equipment. The unit accepts 100-240V AC input at 50-60Hz for worldwide use. A single barrel connector fits both 5.5x2.5mm and 5.5x2.1mm centre-positive sockets.
Check device voltage and polarity before ordering
Your equipment must require exactly 12V DC and draw 3A or less. Confirm the DC jack measures 5.5mm outer diameter with a 2.5mm or 2.1mm inner pin. Verify the polarity symbol shows centre positive and sleeve negative. The adapter is indoor only and needs a hard, flat surface with clearance for heat dissipation.
Sustained load behaviour and protection
Built-in over-voltage, over-current and over-temperature circuits protect connected gear during continuous operation. The regulated design delivers stable voltage with low ripple across the full 36W range. Total cable length is 205cm (6.7ft) from the wall plug to the barrel tip. The black ABS housing weighs .44 pounds and measures 14.33in W x 12.83in H x 9.06in D.

Questions about this item
Does the Dell AL-1230 adapter come with both 5.5x2.5mm and 5.5x2.1mm tips, or do I need to buy a separate connector?
The single barrel plug fits both 5.5x2.5mm and 5.5x2.1mm sockets; no extra tip or adapter is required.
My device needs 12V at 2A — is the 3A version safe, or should I look for a lower-current model?
The 3A rating is a maximum; it will safely supply any 12V device drawing 3A or less, including 2A loads.
The listing says 36W — will that be the actual power delivered to my monitor after cable losses?
36W is the maximum continuous output at the plug; typical cable loss over the 205cm lead is small, so the monitor receives nearly the full rating.
