Mar 12 04:36:52 <brolin_empey> Is it technically possible to make a USB combination cable with a full-size Type A plug on one end and both a Type C plug and a microUSB plug on the other end?  If yes then is it feasible to productise such a cable?  Apparently StarTech does not offer such a cable even though I have bought and use their full-size USB Type A plug to microUSB plug/miniUSB plug combination cable.  StarTech does make a combination cable with a full-size USB Type A plug on one 
Mar 12 04:36:52 <brolin_empey> end and a microUSB plug on the other end with adapters attached to the end of the cable to convert the microUSB plug to an Apple Lightning plug or a USB Type C plug but this cable costs around 25 CAD each so I have only two and you have to manually connect and disconnect things on the end of the cable;  the microUSB/miniUSB combination cable has both the microUSB and miniUSB plugs on a rigid T-shaped part on the end of the cable so nothing has to be manually
Mar 12 04:36:53 <brolin_empey>  connected and disconnected on the cable.
Mar 12 04:39:54 <Vajb> I have one cable which has three wires coming from usb a
Mar 12 04:41:00 <Vajb> they have micro usb, lightning? (that apple thing which doesn't care which way it is entered) and samsung tablet plug
Mar 12 04:41:24 <Vajb> it came with powerbank
Mar 12 04:42:55 <brolin_empey> I know I can buy microUSB↔USB Type C adapters.  I already have some but they are small and easy to lose because they are not permanently attached to a cable.
Mar 12 04:43:35 <Vajb> maybe look from ebay for such cable
Mar 12 04:44:39 <brolin_empey> Vajb: Yes, eBay is the ultimate dollar store.
Mar 12 04:47:21 <Vajb> it has never failed to amaze me with its stock...
Mar 12 05:55:31 <DocScrutinizer05> brolin_empey: >>both a Type C plug and a microUSB plug on the other end<< would you like the USB-C negotiates 24V VBUS getting fed to the micro-USB plug?
Mar 12 05:55:57 <DocScrutinizer05> surefire device killer cable
Mar 12 06:01:24 <brolin_empey> DocScrutinizer05: I do not know a lot about USB Type C because I have little experience with it so far.  I asked about the possibility and feasibility of creating such a cable because I thought that someone like you in this channel would know more than me about the involved hardware/technology.
Mar 12 06:09:13 <DocScrutinizer05> brolin_empey: it's feasible but stringly deprecated since it's dangerous
Mar 12 06:09:24 <DocScrutinizer05> strongly
Mar 12 06:10:57 <DocScrutinizer05> you could connect a usb2 peripheral to the micro-plug while on C plug another device negotiated VBZS=9, 12, even 24V
Mar 12 06:11:13 <DocScrutinizer05> VBUS*
Mar 12 06:11:34 <DocScrutinizer05> all clear?
Mar 12 06:11:46 <brolin_empey> DocScrutinizer05: OK, thank you for your knowledgeable answer.
Mar 12 06:11:55 <DocScrutinizer05> yw :-)
Mar 12 06:12:21 <Vajb> oh, they have different voltage
Mar 12 06:13:10 <DocScrutinizer05> usb3 (C) _can: negotiate higher supply voltages, yes
Mar 12 06:14:02 <DocScrutinizer05> one of the "big assets" of USB3
Mar 12 06:14:13 <DocScrutinizer05> fast charging
Mar 12 06:14:31 <DocScrutinizer05> even of tablets / laptops
Mar 12 06:15:05 <DocScrutinizer05> 24V  iirc 2A  = ~50W
Mar 12 06:15:36 <DocScrutinizer05> vs 5V@1.5A = 7.5W
Mar 12 06:20:17 <DocScrutinizer05> brolin_empey: https://en.wikipedia.org/wiki/USB_hardware#PD
Mar 12 06:20:52 <DocScrutinizer05> 20V@5A = 100W
Mar 12 06:25:57 <DocScrutinizer05> Vajb: brolin_empey: ^^^ needs special chargers  which funny enough come with USB-A-F receptacle(s)
Mar 12 06:34:31 <DocScrutinizer05> datasheet for USB-C *charger chip*(!!!):  117 pages

Mar 12 10:25:58 <sixwheeledbeast> Yer, you have to increase the voltage to transfer the same amount of energy via such small a conductor.
Mar 12 10:27:16 <sixwheeledbeast> P=I*V   24Vdc @ 2A = 48W
Mar 12 10:30:31 <Maxdamantus> when do we touch, when do we kiss?
Mar 12 15:42:36 <sixwheeledbeast> It's SELV not HV...
Mar 12 22:22:23 <AlexNoise> evening
Mar 13 00:20:59 <brolin_empey> DocScrutinizer05: The Wikipedia article you referenced says “As of 14 June 2007, all new mobile phones applying for a license in China are required to use a USB port as a power port for battery charging.”.  Does that mean the USB port has to use a standard USB connector?  Does Apple still use their own connector instead of a standard USB connector on Apple iOS computers intended for sale in or use in the PRC?
