Description
This is a IEC 60320 C7 / C8 type appliance coupler protection or dust cover. It is used to protect the inlet plug of power supplies or battery chargers.
I use it to protect my camera and DJI mavic pro drone power supplies when travelling.
See https://en.wikipedia.org/wiki/IEC_60320#C7.2FC8_coupler
It seems to fit all the supplies and chargers I've tested so far.
