Just give me the base, with a USB C socket to suit the battery, and I'm happy. Surely that satisfies the new regulations?
The text of this regulation is written (like every legal text) very vague.
The EU wants to reduce plastic garbage, which is a good thing. Therefore they force every company which is selling electronic products to offer these from 2025 on only with a USBC connection.
This is a very good idea, because this stops the idiotic prioritary power plugins. See what Apple did for decades and other brands too. If you buy a Walki Talki and this needs again a special power connection, which is not compatible with anything else in the world, you produce garbage for the future by default.
But this does not mean that the brands are not allowed to put a USBC charger or the charging base into the camera package.
With the power plugin there are different opinions out there. In case that the EU wants to avoid this too, then IMHO the brand should offer something cheap in their webshop.
Regarding the base this is different. I have not seen yet a legal text that forbids battery charging base in the camera package.
As long as every producer offers different batteries, which are neither compatible with other brands nor compatible with other models of the same brand, they are IMHO obliged to pack this individual base to the camera for free. Of course with an USBC connection.
In my view more and more brands try to use legal requirements for USBC compatible power plugins as an excuse not to deliver the base, which in reality has nothing to do with power plugins. Or show me the legal text which explicitely mentions the battery charging base.
If we would follow the arguments of the industry, they should offer these individual battery charging bases for free or i.e. 10€ on their webshop. Otherwise they give us the impression to become greedy. Camera prices increased dramatically over the last 6 years. There is no reason to ask 50, 100, 200€ for a charging base, which should be for free included already with the camera at that price level and which costs around 10€ in the production.
Again Leica leads this with their price of the Leica Q3 43 (6.750€) without a charging base. You can buy it from them for 150€ and in the US for 200$.
