Prongs of Anker Nano Universal Charger (4-in-1, 100W, Smart Display) Are Difficult to Extend
All prongs are moving parts, so they may feel slightly stiff during initial use. This is normal. Try opening and closing them 10 or more times to make the movement smoother.
Make sure the other prongs are fully retracted. Otherwise, another set of prongs cannot be extended.
To extend the US / UK prongs, press the button down first, then keep holding it while pushing the prongs out.
If the steps above do not resolve the issue, please record a video showing you extending the prongs so we can quickly identify the issue.
