Came across this and though I would share.

I want an iPhone 6Pius...

That cable is a Frankenstein's monster that should be killed with fire, but the link you gave us led me down a rabbit hole. The first post mentioned a keyboard with "RGB" or whatever, which reminded me of the Optimus keyboard, which made me go to their site to see if it was still for sale (which it is), which then led me to their store where the keyboard is listed among a variety of junk products. That's where I saw this, and realized I know absolutely nothing about how the European power plug standards work. So you could just plug stuff into any part of that thing in any direction and it would charge? The idea that a power strip for a two-pronged standard would have 15 holes in it is very strange to me, but I can't put my finger on why...

Anyway, random thought.

Random thoughts is probably why I posted the original link.

Euro 2-pin AC power is the same as USA, just the pins are round and the voltage is double.

That grid of prong sockets on the 15 hole power bar could be adapted to work with flat prong North American plugs. The AC feed apparently runs in a diamond pattern under the sockets, so each hole has the four surrounding pins powered by the opposite side of the AC. Plugs cannot be plugged in on an angle, only north-south or east-west.

Flat prong USA style AC plugs are such a poor design, alas, but I expect we are stuck with it until the end of time.

The euro (not UK though) sockets are not polarised, so you can plug things in in either direction.
If the socket(plug is grounded, there are two grounded metal prongs in the socket (12 and 6 oclock), that connect to flats on the plug, so you get ground connection either way. image

A grounded plug can be inserted in a non-grounded socket (on the theory that the socket would not be in an area where grounding would be required.
A non-grounded plug (unless it's the flat plug, only to be used on double-isolated things) does not go into a grounded socket, on the theory that a non-grounded tool shouldn't be used in an environment where a grounded socket was required.
But now grounded sockets a required everywhere (at least in Sweden) on all new construction and major rework. Non-grounded round plugs are very rare to find on new goods - it's either grounded or double-isolated flat one...

All the socket are recessed so you can't get your fingers on the pins when they're making contact in the socket (though I still have a few sockets here from when the house was built in the 50s and they have only a very shallow recess...)
