Default What is inside that small cylinder in a laptop adapter?

"AliceElma" wrote in message

What is inside that cylinder thing that is at the end of a AC adapter of
a laptop or notebook?
Is it like a load matching thing? Current limiter?



Could be a choke (balun? grins), to reduce, possible, interference, or
signal reflection ( [ / ] refraction).

Any tech ex(pert)s?
