Universal 12V 1.5A power adapter

This BASEUS AC adapter converts 100-240V mains input into a regulated 12V DC output at up to 1.5A. It is intended for devices that draw less than 18W and accept a 5.5mm outer and 2.5mm inner barrel connector with centre-positive polarity. The 1.4m cable provides flexible placement for routers, CCTV cameras, LED strips, hubs and similar low-power equipment.

Output headroom and safe loading

The unit delivers a maximum of 1500mA, yet the supplier recommends operating below 80 percent of that limit to avoid overload. It will comfortably run loads such as 160mA, 300mA, 450mA, 850mA, 1A, 1200mA or 1350mA devices. Attempting to power monitors, LED lamps or any device exceeding the 18W ceiling will exceed the adapter's capacity and is not supported.

Barrel connector and usage limits

The fixed 5.5mm by 2.5mm plug dictates compatibility; reversing the positive inner and negative outer contacts will prevent operation. The adapter is an AC-to-DC supply only, not a battery charger, so it cannot charge mobile phones or any battery-powered device. Input frequency tolerance of 50/60Hz allows worldwide use with a suitable plug adapter, but the output remains strictly 12V DC.

Questions about this item

Will the 5.5 mm × 2.5 mm barrel plug with positive tip polarity fit the CCTV camera I already use?

Yes, the adapter uses a 5.5 mm outer and 2.5 mm inner diameter barrel with centre-positive wiring, matching the common polarity for many CCTV cameras and DVRs.

How can I verify the adapter is delivering a stable 12 V output once connected?

Measure the DC plug with a multimeter set to DC volts; it should read close to 12 V under load, and the connected device should power on without voltage-drop warnings.

Does the package include any extra cables or tips, or just the 1.4 m cord with the fixed barrel plug?

The box contains only the AC-to-DC adapter with its integrated 1.4 m cable and fixed 5.5 mm × 2.5 mm barrel plug; no additional tips or extension leads are supplied.
