Power Output and Connector

This 12V 2A AC adapter delivers 24W through a 5.5x2.1mm centre-positive barrel connector. It suits devices such as routers, switches, CCTV cameras and external drives that require exactly 12 volts and up to 2 amps. The 4.9ft cord provides flexible placement.

Safety Certifications and Protections

The unit is UL listed as a Class 2 power supply and accepts 100-240V input at 50/60Hz. Built-in safeguards include over-voltage, over-current, over-temperature and short-circuit protection for reliable operation.

Compatibility Checklist

Verify that your equipment shows a centre-positive polarity symbol, a 5.5mm by 2.1mm port and a 12V requirement not exceeding 2A. Devices with different connector sizes or voltage needs will not work without a separate adapter.

Questions about this item

How do I connect the 5.5x2.1mm centre-positive plug without damaging my device?

Match the centre-positive symbol on your device before plugging in; the 5.5 mm outer and 2.1 mm inner diameter must seat fully, and the 4.9 ft cord should run without strain or sharp bends.

Will the internal protection circuits or the 4.9 ft cord need replacement over time?

The built-in over-voltage, over-current, over-temperature and short-circuit protections are solid-state and maintenance-free; only the cord could wear if repeatedly bent tightly, so inspect it periodically for cracks.

At what load does the adapter hit its thermal limit during continuous operation?

The 12 V 2 A (24 W) rating is the sustained maximum; running at full load in a confined space will trigger over-temperature protection first, so keep ventilation clear.
