It wasn't just a railing that led to the platform, it was a metal cable fully charged with the ship's electricity.

那并不是扶手，那是一根铁索，通过了船上的电流，直达到平台。

The joke was that there'll be certain old guys who forgot the charging cable but didn't notice until Covid was over because they never actually switched their machines on.

开玩笑的是， 有些老家伙忘记了充电线， 但直到 Covid 结束才注意到， 因为他们从未真正打开过机器。
