And how am I supposed to know that when looking at a device that has a USB-C port for charging, and the instructions on the charger [0] say "Nintendo Switch can be charged by plugging the AC adapter into the console's USB Type-C connector."
> New Annex (Part I): It requires that mobiles phones and the similar radio devices, if they are capable to be recharged via wired charging, are equipped with the USB Type-C receptacle and, if they also require charging at voltages higher than 5 volts or currents higher than 3 amperes or powers higher than 15 watts , incorporate the USB Power Delivery charging communication protocol.
Nintendo will have to get its crap together and properly support Power Delivery, the burden is not on you.
Nintendo always does something that's JUST slightly off with their consoles that make them annoying as hell to use.
With the switch it's the screwed up USB-C implementation and the fact that you can't use bluetooth headphones (it has BT support, but only for the controllers)
With the DS, the wifi only supported WEP, not WPA, even though WPA2 had been released by the time the DS came out
The Switch was updated to support BT headphones, with the caveat that you can only have 2 BT controllers simultaneously connected with the headphones, and the controllers can’t be switched while headphones are in.
The reason for the limitation is bandwidth and latency.
Multiple devices on one Bluetooth controller have to timeslice in 4 millisecond (iirc) chunks. Audio devices in a high quality mode consume a substantial amount of the overall bandwidth. It also doesn't matter if your packet consumes the full size of a chunk of not, all of them are equally sized. You'd have to do two audio chunks and one controller chunk * 2 controllers to maintain a 60 Hz sample rate on the controllers.
By trying, returning the device (ouch for the shop), and then complaining to your local enforcer of Radio Equipment Directive (ouch for the manufacturer).
The only comment I could see in the article on that topic is this:
> the EU simply said that "consumers will be provided with clear information on the charging characteristics of new devices, making it easier for them to see whether their existing chargers are compatible.
Which is super disappointing, as the person who wrote TFA clearly didn't read anything other than the press release. The actual supporting documentation is here [0] and says:
> on the packaging or a label, manufacturers would have to
provide information on specifications relating to charging capabilities, in line with annex Ia (amended Article 10(8) RED). This includes a description of the wired chargers' power requirements (the text displayed should read: 'The minimum power delivered by charger shall be equal or higher than [xx] watts') and specifications on charging capabilities ('USB PD fast charging' and an indication of any other supported charging protocols).
Which is still not great - this doesn't cover cables for example, and it doesn't guarantee that it will be printed on the device. Here [1] are apples chargers in the UK - unless they're side by side it's impossible to tell which one of those chargers is which, and even at that unless you know for sure one of the devices is X, its' really quite difficult to tell.
It's worse than that, just because a charger can support 60W doesn't mean it supports every standard combination of volts and amps below that level and just because a device can charge at 60W doesn't mean it uses the same combination of volts and amps your charger supports. I have a 100W charger than can't "fast charge" my phone (USB-C on both ends) because they only overlap capabilities on lower wattages.
