In researching the PR China standards for mobile device chargers (CCSA YD/T 1591-2006, later updated to YD/T 1591-2009) I have been unable to find detailed English language information and references for the updated (2009 December) version. Using Google translate with some Chinese language articles, I have been able to piece together some of the changes (compared to the original 2006 specifications) but I have not found any articles (English or Chinese) that provide answers to some remaining questions. I put together the following chart to illustrate some of the open questions. If anyone has access to the updated Chinese standard itself (CCSA YD/T 1591-2009) or knows of good English or Chinese references on this subject, I hope they will add that information here - or directly in the Wikipedia article.

While the idea behind the agreement was surely good, all major cell phone manufacturers now ship an USB power supply with their products, which means that the electronic garbage just changed its form. Not sure if there is a compliant way to get this current state of the industry into the article... WooShell ( talk) 18:16, 1 July 2012 (UTC)
An editor today made several minor changes to the article, including changing several "-ise" spellings (harmonisation, standardisation, etc.) to the "-ize" equivalent (harmonization, standardization, ...). I'm not sure what the editor's motivation was but Wikipedia's Style Guide seems to discourage this kind of spelling revision except in specific cases.
See Wikipedia:ISE#British_English_with_.22-ise.22 and Wikipedia:Style_guide#National_varieties_of_English
One changed word was inside a direct quote (changed from "Adaptor" to "adapter"). In another case, the changes were made to Harmonisation / Harmonise as used in a direct quotation and in the title of a referenced article. Regardless of other spelling considerations, words in direct quotes should retain the spelling of the original quote / citation.
Lastly, two minor grammar changes were made at the same time but both changes altered the meaning of the sentences (one subtly, the other became unintelligible).
For all of these reasons I reverted the entire change today and made additional minor changes to improve clarity. Pugetbill ( talk) 16:09, 23 March 2013 (UTC)
I have a question and I'm finding it difficult to locate an answer. I'm beginning to suspect one statement in the "USB Power Delivery specification" section may not be accurate / verifiable:
My question: what is the maximum allowable current at 5V for a USB dedicated charging port when connected to a device through USB-PD-certified cables equipped with micro-USB connectors?
Until / unless someone can reliably verify (with citation) the USB-PD "10W maximum" for 5V Power Delivery, I propose this sentence be modified to read:
According to the USB Power Delivery specification, the maximum current allowed for USB micro connectors at 12V is 3A (3A x 12V = 36W). Likewise 3A is the limit for 20V Profiles when using USB micro connectors (3A x 20V = 60W). The thing I find odd is that USB PD Profiles 1 through 5 only support 2A at 5V although they support 3A at 12V and 20V (for USB micro connectors). Why would 3A be acceptable at 12V and 20V but not at 5V? All of these profiles presume PD-certified cables are detected. If "old" (non-PD-certified) cables are in use, the original USB Battery Charging specification limit of 1.5A at 5V (e.g. 7.5W) is apparently enforced.
It is mentioned in the Power Delivery standard (I believe) that the 5 "Profiles" are just guidelines(?) so perhaps 5V @ 3A (i.e. 15W) is allowed / supported for USB micro-equipped PD cables / ports??? i.e. just because it is not explicitly included in one of the (optional?) profiles doesn't mean it is not supported???
I hope someone can provide a citation for a reliable / authoritative source that clears up this question. I've searched but have had no luck so far Pugetbill ( talk) 01:50, 27 October 2013 (UTC)
Is it okay if this article has a photograph of an actual European power supply
Thanks

Hello fellow Wikipedians,
I have just modified one external link on Common external power supply. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.
An editor has reviewed this edit and fixed any errors that were found.

The European Commission announced they would be revisiting this issue, supposedly to try and force Apple into joining the world of USB-C. Would it be worthwhile to include this? Also developers claim that standardization would hamper development, would that be worth adding to this article? Bgrus22 ( talk) 07:19, 30 January 2020 (UTC)
I would like to propose that this article be MOVED (renamed) to EU Common external power supply (EN 62684:2010)
Background / rationale for the proposed move / name change:
The EU has recently (2020/2021) announced plans to produce a new power supply ("charger") standard / mandate for mobile devices (mobile phones, etc.) sold in the EU.
It's not yet clear (to me anyway) whether this new / proposed standard will be simply a revision of the previous EU "Common EPS" standard (EN 62684:2010) or something completely new and different. I suspect it will be considered something new / different. But even if it is only an extension of the existing standard, I assume the name of the standard/specification would still change to (something like) "EN 62684:2022 " (not the current "EN 62684:2010")
I suggest it would be less confusing for Wikipedia readers if we would create a completely new article for any new 2022+ EU standard rather than trying to incorporate all relevant information into this older article - which was created only for the 2009/2010 EU Common EPS standard. As preparation for that day when there is more concrete information about the new standard, I suggest we rename this current article to make it more clear that THIS article refers to the 2009/2010 Common EPS - not to the "next generation" (2022+?) EU power supply / mandate.
I don't think this article MOVE/name change is particularly urgent and I'll be interested to hear if anyone has concerns about this proposed MOVE or has questions or better alternative suggestions. But if, after some time, there are no objections or alternative proposals in the comments here / on this talk page, I'd be happy to make the suggested MOVE in the coming weeks / months.
