12V 1A AC Adapter Overview
This BASEUS adapter converts 100V to 240V AC input into a regulated 12V DC output at a maximum of 1A. It features a 140cm cable terminated with a 5.5mm by 2.5mm barrel plug. The unit includes built-in safeguards against overload, over-voltage, over-current, over-temperature and short circuits. It suits devices requiring up to 12W of power.
Suitable devices and limitations
The adapter suits 12V equipment drawing less than 1A such as LED strips, CCTV cameras, routers and small audio gear. It is not for devices that need a higher current rating or a different output voltage. Buyers needing more than 12W or a different connector size should look at other options.
Critical specification check
The DC plug has a 5.5mm outer diameter and an inner diameter ranging from 2.1mm to 2.5mm with centre-positive polarity. Confirm that your device matches this exact connector geometry and the 12V 1A rating before ordering.

Questions about this item
What voltage and connector size must my device use to work with this 12 V 1 A adapter?
Your device must require 12 V DC, draw no more than 1 A, and accept a 5.5 mm outer by 2.5 mm inner barrel plug with centre-positive polarity.
Can I keep using my existing 5.5 mm × 2.1 mm tip with this power supply?
Yes, the plug accepts both 2.5 mm and 2.1 mm inner diameters, so a 5.5 mm × 2.1 mm tip will fit and maintain the correct centre-positive connection.
How can I confirm the adapter is delivering power correctly once connected?
The target device should power on normally; if it fails to start or shows unstable operation, verify the device draws under 1 A and that the polarity matches centre-positive.
