The physical place to charge them is the same.
The point in the discharge cure at which to charge them (45%) is the same. (Letting the battery drop to below 45% is asking for a battery that will need to be replaced sooner than it should need to be.)
The connector is the same (Type C).
The question can mean many things, but any charger can be used to charge any phone if the connector is the same.
(And please ask a question once, not 4 times. We're all volunteers here - we'll get to your question when we get to it.)
