Power adapter for 12 V DC devices
This 48 W adapter delivers 12 V at 4 A for LCD monitors, LED strips and similar low-voltage equipment. It accepts a 100-240 V AC supply at 50 60 Hz, making it suitable for worldwide mains voltages. The package includes the adapter and an AC power cable.
Check voltage polarity and plug size before ordering
Your device must require exactly 12 V DC with a centre-positive 5.5 mm outer and 2.1 mm inner diameter barrel connector. The 90 cm output cable and 2.5 mm pin centre should match the equipment jack. Verify the unit’s maximum current draw does not exceed 4 A.
Four protection circuits handle sustained loads
Over-voltage, over-current, short-circuit and over-heat safeguards operate continuously during extended use. The IC-based board and all-copper nickel-plated plug are tested through load aging before shipment. The 90 cm cable length remains fixed, so plan routing for permanent installations.

Questions about this item
Does the package include both the adapter and a mains lead, or must I buy the AC cable separately?
The box contains one 12V 4A adapter and one AC power cable, so no extra mains lead is required.
My device needs a 5.5 mm outer and 2.1 mm inner barrel plug — will this adapter fit?
The supplied DC connector measures 5.5 mm outer diameter and 2.5 mm inner diameter, so it will not match a 2.1 mm centre pin.
What does the 48 W rating mean for a monitor or LED strip drawing up to 4 A?
At 12 V the unit delivers up to 4 A continuously, giving a maximum of 48 W for compatible low-voltage devices.
