Questions about USB-C on new iPad Pro
I was hoping someone could help clarify some questions I had about how the new USB-C interface can be used on the new iPad Pro. While I have a laptop (Dell) with a USB-C interface and have used it for connecting a docking station, I’m not a big expert when it comes to the specs and capabilities. I’ve spent the past hour reading up on it, but I’ve found some conflicting information as well as a bunch of warnings about issues with charging, improper cables, etc. that can cause damage to your devices.
On all of my previous gadgets, which used USB-A style chargers (with micro or lightning on the other end), I never gave much thought to it and just plugged it into whatever I had using whatever cable I had without issue. But it sounds like that isn’t always the case with the USB-C stuff. Anyway, my questions are:
1) The short 1m cable that comes with the iPad Pro obviously works for charging and (I assume) some level of data transfer, but can’t be used for “high speed” stuff like 4K displays, correct? Would that mean that this is a USB 2.0 spec’d cable?
2) Most of my chargers are USB-A style, including some nice Anker ones that I use with everything. From my quick search, USB-C style chargers are more expensive and often only have a single port (plus maybe some A ports). I bought some Anker USB C-to-A cables on Amazon, with the thought that I could, at possibly a slower charge rate, plug my iPad into a USB-A charger port when necessary. The cable I bought is rated highly but USB 2.0 (I assume due to the 480mbps transfer speed). Will this be a problem? Can it cause any issues? Does a 3.0 C-to-A cable make any difference?
3) I understand the port on the iPad Pro is a USB 3.1 Gen 2 (NON-ThunderBolt). I read that this is “electrically compatible” with USB 3.0 and 3.1 Gen 1, but what about Gen 2? Will there be any issues, outside of less power/data throughput, with using a 2.0 cable? I also bought some Anker USB C-to-C cables that are 6 feet long to give me extra distance to the charger, but see that these are 2.0.
4) Again, coming from a USB-A style world, everything was (to my knowledge) 5V with varying degrees of wattage/amps. But after looking into USB-C more, I see it actually supports different voltages, ranging from ~3-20V. Some USB-C chargers are only capable of lower voltages. I can’t for the life of me find what the iPad requires/supports. I hope/assume that it is able to regulate this, as I would expect a device that uses 5V getting hit with 20V could cause damage (right?).
5) What about docking stations and other types of devices? Could I charge my iPad with my Dell docking station’s USB-C cable? I assume most/all of the accessories won’t work, but what about power?
Sorry for the long list of questions, but again I am not able to find anything iPad specific and wanted to ask before just plugging stuff in. My main concern is obviously not doing anything to fry or otherwise damage my new iPad.
