In 2021, the European Commission proposed the use of USB-C as a universal charger. [92] [93] [94] On 4 October 2022, the European Parliament voted in favor of the new law, Radio Equipment Directive 2021/0291, with 602 votes in favor, 13 against and 8 absentions. [95] The regulation requires that all new mobile phones, tablets, cameras, headphones, headsets, handheld video game consoles, portable speakers, e-readers, keyboards, mice, portable navigation systems, and earbuds sold in the European Union and supporting wired charging, would have to be equipped with a USB-C port and charge with a standard USB-C to USB-C cable by the end of 2024. Additionally, if these devices support fast charging, they must support USB Power Delivery. These regulations will extend to laptops by spring 2026. [96] To comply with these regulations, Apple Inc. replaced its proprietary Lightning connector with USB-C beginning with the iPhone 15 and AirPods Pro second generation, released in 2023. [97] See also [ edit ] Thunderbolt3 40Gbit/s passive cables are only possible <0.8m due to limitations of current cable technology. It’s quite easy to provide overvoltage protections inside a USB-C device, I’ve done it! Add a crowbar with a zener, or one of those “protect from overvoltage” chips, problem solved.
Say, you plug a charger into a laptop. The charger provides a pull up on the CC line, the laptop will detect that, and if your laptop is USB-C charging-capable, it will put a pull down onto the CC line. The charger will then provide 5 V, and will get ready to talk PD for anything higher than that. As you can see, before higher voltages are possible, you first have to go the 5 V and analog communications way. Put your 5.1 kΩ resistors onto CC pins, get 5 V, and talk the power supply into giving you a higher voltage from there.

All older USB connectors (all Type-A and Type-B) are designated legacy. Connecting legacy and modern, USB-C equipment requires either a legacy cable assembly (a cable with any Type-A or Type-B plug on one end and a Type-C plug on the other) or, in very specific cases, a legacy adapter assembly. a b Anthony, Sebastian (2015-06-02).

Your next step (which should be your first step) is to figure out if "your phone" uses late edition of PowerDelivery and can negotiate anything above 5 V level. Schoon, Ben (2018-11-01).

Retrieved 2019-02-25.There are Y-cables out there that will take power from two USB ports to get around this power limit on USB ports but this violates the USB spec and so can have unpredictable results. Unpredictable as in you could see smoke come out of something. It's certainly possible to get power safely from multiple USB ports but this will not be cheap or easy. I’m not a professional writer or anything, but a recurring theme is using the same word twice in a sentence which is hard to follow, as well as including more than one thought per sentence. One random example: In fact, trigger boards don’t tend to give you any current limit information – if there’s risk of overcurrent because the charger cannot provide 3 A at the voltage the trigger board request, you’ll just have to make sure the charger you’re using implements overcurrent protections; those are mandated by USB-C and done by most, that said, you don’t want your device powercycling every few seconds, either. Also, if you want a dual-role port that works with OTG adapters or perhaps can do high-speed lanes, a trigger IC won’t be able to help you, and you can’t just connect multiple PD ICs requesting different functions in parallel to your CC pins. We can try and surpass these limitations in later articles – for now, know that trigger boards have their well-defined place in your USB-C arsenal, and they will help you with your USB-C projects as far as higher voltages are concerned. I Want To Give Something Twenty Volts After entering debug accessory mode, optional orientation detection via the CC1 and CC2 is done via setting CC1 as a pullup of Rd resistance and CC2 pulled to ground via Ra resistance (from the test system Type-C plug). While optional, orientation detection is required if USB Power Delivery communication is to remain functional.
