Questions about this item

How do I install the BASEUS 9V 2A adapter and which polarity setting is correct?

Plug the 5.5 mm x 2.1 mm connector into the device with the centre pin positive and the outer sleeve negative; the tip also fits a 2.5 mm jack. Verify the device label shows 9 V and centre-positive before connecting to 100-240 V AC mains.

What maintenance or replacement will this 18 W power supply need over time?

The unit has no user-serviceable parts; if the 6.6 ft cable insulation frays or the plug loosens, replace the whole adapter. Keep vents clear of dust so the over-temperature protection does not trip under continuous 2 A load.

What limit appears first when the adapter runs at full 18 W output for long periods?

Sustained 9 V 2 A delivery will trigger the built-in over-temperature protection before any other limit, causing the output to shut down until the internal components cool.
