Will this work with an extension cable from USB C to USB C? Will it work with an adapter to plug into a USB 3.0 port?

BEST ANSWER: I'm not always certain of the terminology and I don't want to mislead you. However, I use this device to load files directly onto my Macbook Pro. I think that is a USB port but, of course, Apple has a different name for it.

Haven't tried the first but it seems like it would work. Why would you be plugging it into a USB 3.0 port? It's to store and transfer files to and from an SD card. Enter

I can't comment on the use of an extension cable, but it works just fine with a USB-C to USB Type-A (9-pin for USB 3) adapter plug.

I bought two of them. They work well on my new USB-C Chromebook.With no loading of software, or fuss. There is a nice little blue light indicator that comes on when connected to a USB-C device.

If your phones would support USB host this would allow you to connect and alter an SD card on your phone.

How does this work? I have it plugged into my iPad Air 4th gen with a micro sd card. The Device blinks blue lights but nothing else happens.

Love this card reader!
I had purchased a hub with all the slots in it, but this is so easy to use and I keep it close by new MacBook, as they no longer have a card reader built in. (which is stupid.....)

Works great, but will block the second USB-C port on your MacBook Pro
I use this now that I have a MacBook Pro with USB-C ports and no card slot. Works just fine. It might be a little slower than having a built in card slot, but if it is, the difference isn't noticeable.
It's wide enough to block the second USB-C port on your MacBook Pro. Also, it feels a bit vulnerable having the relatively large surface area hanging off of a small port, so a little caution is required.

Good buy.
It is compact and works easily with my Galaxy S8. I needed no additional apps for it to work. Cheaper than Best Buy's version.

Perfect
Great way to import photos from an SD Card and the speed is noticeably faster than the integrated Card reader on my old MacBook Pro.
