Why cant there be a global standard for orientation of AC /DC Adapters ?
the shape and size and orientation of adapters ?
some go left, some go right instead of being straight
the adapters that are straight are mostly ok on a power board
the adapters made to be left or right can only be used on either the left or right end of the power board
so imagine a six plug power board
with six adapters all facing left, then you cannot plug them in to each power socket
you might be lucky and be able to plug in three

The other issue with adapters is the uk, us, eu, and au variation in plugs.
so quite often manufacturers will send an adapter with a uk plug and then put in an au adapter for it
instead of one global solution which is clip in or slide in plugs

Another area that needs global standard are colors of wiring for audio, colors of wiring for DC and colors of wiring for AC
