The EU is enforcing USB-C on portable devices

--- Quote from: Someone --- get that its all roses and works perfectly for "low power" 5V only devices, that is the problem as it is a convenient "out" or shortcut for the junk suppliers to meet the regulation in wording but not in spirit. Your 3A 5V result assumes the charger has USB-C, which isn't being mandated!
The EU mandate is allegedly about making people reuse their chargers across more devices. But not all devices will charge with only 5V power. So if they only mandate the device connection end, we will still end up with many incompatible chargers as more dumb 5V <1.5A (anything higher requires some negotiation) supplies are produced and shipped.

I think it will work better than you expect. Existing non-C chargers will just work the same as they do now, and any new 'cheap' minimal-function chargers ditto. But phones and stuff will require more power than these chargers can supply, and over time people will buy chargers that work with their devices properly. So when the difference between the chargers is 6 hours vs 1 hour to charge a specific model of phone, the users will migrate to buying the more powerful one. Just as now you buy the quick-charger that's compatible with your phone and not the one that isn't. But you can still grab some random one off a shelf and use that in a pinch. The difference is that the phone-specific charger is now going to be a generic one, so you're more likely to splash the cash since it will work with your next phone too, whatever that happens to be.
What I haven't caught yet, unless someone has resolved it, is what happens to wireless chargers. The upcoming regs affect only wired ones, so will wireless chargers with captive plugs (or plugs with captive wireless chargers, if you prefer) be OK? That seems to go against the regs, and I would have expected a mandate that wireless chargers should be powered from a USB-C source. That may seem a trivial thing right now, but wireless charging is the future, if not already the present.
Simon:
from what I have seen any device will charge on any charger. The dumb stuff may be the problem but those are not phones so not covered. But a phone will use whatever charger you throw at it as it will work out what it is or not. As far as I am aware their is one fast charging system, it has several power/voltage levels but as there is a protocol used to negotiate this any charger and and phone are a match. I still do not see how mandating a USB-C socket on every phone helps unless they are mandating more than that but give the ignorant politicians and public a break, it's more complicated than that and we don't want to overly confuse them.

....because USB-C is the only connector which the PD negotiation works on (it has some extra pins to help).
Simon:
And everyone that makes a device that wants to charge faster will use USB-C no need to make a law about that we needed that 20+ years ago. actually unless I have missed out on some new standard fast charging with negotiation between charger and device charged was already on micro USB, I had a phone and a wireless charger on micro USB that did fast charging. The actual connector was irrelevant, it's a USB thing, it would work on a USB B connector if anyone put one on a battery device.
