Questions about this item

What barrel-plug dimensions does the 12 V 1 A adapter use?

The tip measures 5.5 mm outer diameter with a 2.1 mm inner pin, matching the standard centre-positive barrel jack on many laptops and peripherals.

How do I connect the wall adapter and what mistake should I avoid?

Plug the unit into a mains socket, then insert the 5.5 mm barrel into the device power port; the common error is forcing the plug in upside-down, which can bend the centre pin.
