[QUOTE="Paliswe, post: 829186, member: 48977"] The main problem with USB-c is that the EU has only standardized the physical format, not the electrical. There are three main groups of USB-c for the electrical versions, which in turn each have some subgroups. Originally, USB was at 5V and 0.5A to 1A. With 3A you can't get more than 15W out. As the need for fast charging increased, more power was required and then the voltage had to be raised so that the current wouldn't be too high in the cable. Now there are both 5V, 9V, 15V and 20V. To complicate things further, there is electronics inside a USB-c connector. It "talks" to the socket it is connected to so the whole thing resembles a tango with three parties, the power source, the consumer and the cable in between. All three of these must fit together in order to get the full effect. It's all ending up into everybodys need to buy a separate battery charger and cable for each item (almost). It's good to have a standard, everyone has their own... it's a total mess! It's worth noting that you can't extend a USB-c cable. If the cables are different (and you cannot tell the difference, nothing is marked), you may end up with one "standard" on one end of the cables and a different "standard" on the other end of the cables.
