No, I can't. I need to sell it on both markets to make it profitable. There's no way to have that large margins it could sell just in the US.

If you need to sell it on both markets and can't have two production lines, I guess your product will have USB-C port and your superior charging port, like the new MacBooks having type-C and magsafe.

And that's supposed to be good? I really don't understand this world...

It's good because until you invent this new cable, we can have everything work with USB-C.

Not betting on your ability to come up with a new type of charging cable is not as big deal as you imagining it is. Maybe you should come up with a prototype before demanding all type of charging cables be allowed?

And what do I do with the prototype then? There's nobody buying.

This probably means your invention don't add enough value. Throw it away like all other prototypes who fail to create enough value to warrant a production line.

No, it means somebody regulated a single connector type.

I guess all failed inventors and entrepreneurs have someone to blame.

Nobody is even going to be trying after this comes into effect.

Having three computers of different brands in the family (an HP, a Lenovo and a Microsoft Surface), it's certainly been useful in the past to be able to share a single charging port for all computers and most phones in the family.

In fact, USB-C and magsafe are complementary. USB-C is commonly used by displays to provide docking station functionality, so I can buy any display and use it with any computer (instead of having to buy a proprietary docking station that is different for each model). If I'm travelling, I can enjoy the more robust magsafe connector but I can also use USB-C if needed.

IF you can't be profitable at anything other than global scale, maybe your (wholly hypothetical) invention is not that great.
