most people will already have lots of usb -B ports and chargers though, so the USB C device becomes the odd one out.
I learned the hard way that I had no usb C <-> USB cables in the house - I'd bought a refurbished Yoga 3 tablet which uses USB C and the idiot sellers shipped it with an incorrect cheap usb -b charger & cable. So I had a tablet, with a bit of juice in its battery, but absolutely no way to test it properly or charge it until I was able to get amazon to ship me a USB-C. Then in the stress of sorting that, I ordered a USB B by mistake so when my next day prime package arrived I had to send it back & start over.....

finally I got the missing bits and have to say the USB C goes in with a satisying click and no hassle about is it the right way up . Though the lenovo android tablet still tells me it would prefer a fast charger , even though I have 2 makes of 2 amp ones. Turns out that Lenovo have a proprietary fast charge solution that only works with Lenovo brand chargers, and no one, not even Lenovo, sell spare Lenovo chargers...

I also learned in the process, from Google & friends, that a cheap USB C connection can burn out a PC or TV usb2 port , or damage a motherboard very easily, by asking for too much current.

So if the OP does get a USB 3 device, and plans to sometimes charge via USB 2 on PC , be very careful to get branded and built-to-spec cables for that. I am charging my new tablet via the same dedicated USB C cable into an amazon fast charger and never connecting directly to PC, just to be safe.
I recommend reading up on fast charge standards , or lack of.... before assuming one charger will play nicely with all devices.
it may be low tech - but sticking " this side up" coloured blobs onto my micro usb cables works for me
