Questions about this item

Will the 5.5 mm × 2.5 mm barrel plug need replacing over time?

The plug is a standard 5.5 mm × 2.5 mm barrel that also fits 5.5 mm × 2.1 mm sockets; no moving parts are inside the adapter, so the connector itself does not wear out under normal use.

What limits continuous operation of the 3 V 1 A output?

The adapter is rated for 3 W maximum output; drawing more than 1 A or 3 W will trigger the built-in overload protection and shut the unit down.

How much heat does the 100-240 V AC input generate during all-day use?

The flame-retardant shell is tested to withstand 1382 °C, and the switching design keeps the housing only warm to the touch when supplying up to 3 W continuously.
