The EU is enforcing USB-C on portable devices

Perhaps your awareness is lacking. There are several fast-charge systems and the problem is, AIUI, that the 'fast' bit only works with compatible devices. Use the wrong charger and it will charge, but not fast.

Making them all use USB-C PD means there will be one system where 'fast' will work with whatever is plugged in (that can do fast, obv).

Manufacturers like Samsung and Xiaomi have an interest in not being compatible with other systems, so they're not going to join up unless you make them. Which is what this push is partly about.

at this point isn't the UK just insisting on doing every opposite of what the EU does?

Pretty much - if the EU mandated breathing oxygen the UK would state that oxygen was for losers and announce the new UK standard for breathing carbon dioxide.

Well our ever not very detailed BBC may have missed a lot of the detail of the law but I did not hear anything about standardising on a charging protocol. That is the sort of nuance that politicians miss out on too and end up making useless laws. If all they do is make a law about the connector they have just wasted their time and tax payer money enacting something that is good as saying that phones must always be charged with electricity.

I haven't checked whether the current versions support this, but the original version of USB-PD was negotiated over Vbus, and therefore worked with standard USB-A plugs.

So you haven't bothered to do any research or even read this very thread, then.

Simon:
OK so has the charging standard also been mandated?
