You can find cheaper, lesser-branded/unbranded ones on Amazon & eBay. Also cables with C on one side and whatever on the other.

Any USB-C to USB-A adapter will work. Link-> Anker USB-C to USB High Speed adapter - Amazon.com

I use a couple of $9.99 Philips High Speed USB-C to USB-A adapters, that I picked up from target.
