Clearly, the law will dictate a USB-C port, not a custom cable. This means Apple will have to retrofit a connector to the Apple Watch to sell it in the EU; can't just use a magnetic charging "cable" (obviously it's more than just a cable - and this is why they won't be permitted). And for the above to be true, a laptop will need to be able to charge off any USB charger, even a tiny phone or car one. |

No requirement to operate off an impractically underpowered supply is made. |

That's their language, not mine. If you have to purchase a laptop charger with your laptop and can't use your phone charger, then the above isn't true. |

Oh, and no, you don't need to add a connector if you don't already have one - it explicitly states it applies to devices with a charging port. |

There's no reason at all that can't be done with USB-C. --- End quote --- There is: handling USB-C is much more complex than handling a DC input. So that requires dedicated ICs, multi-layer routing, etc. And if the port (which is what users will expect) can be used for data as well, then it must also be connected to the motherboard's chipset. All that would make a separate board much harder and more expensive. Are you really comparing a simple board with a DC barrel jack and maybe some ESD diodes with what is required to handle USB-C power delivery? Yeah. :popcorn: --- End quote --- There are 6 pin power only USB-C connectors. Being compliant with the standard only requires 2 resistors. Or if you want PD, then it's an extra IC which is about the complexity of a STM8. --- Quote from: Monkeh on November 01, 2022, 07:18:44 pm --- --- Quote from: Miyuki on November 01, 2022, 07:01:07 pm ---And the hard soldered end in the laptop ruins the board. --- End quote --- For many years all decent laptops have had the charging port off the board for easier replacement. There's no reason at all that can't be done with USB-C. Anyway, nobody's requiring the loss of a dedicated charging port - only the provision of a USB-C port capable of charging as a universal option. --- End quote --- Plus, all the laptops I use have PD charging on more than one port. So it's even redundant, making it more likely there is a working port. |
