Ever lived in a third world country? It's typical that an expensive thing is available as a package, but no individual accessories are carried by seller.
Not lived but visited some.
But this has nothing to do with third world countries, I see colleagues with $1 cables from Ebay instead of the $15 original cables and probably also the cheap chargers, it is a global phenomenon where people don't want to spent more money if they
think they get the same goods for less money but bring in a deathly device in disguise in to their homes and expose them to their children.
Actually it is very simple no mains connected electronic device should be allowed to be imported without certificates that this product complies to the safety regulations for that country.
Or ban mains connected devices from being imported by consumers just as other illegal products such as animals, meat, drugs, etc.
Let manufacturers build DC devices and let the consumers buy a certified dc power supply in their own country.
