Amazon currently has the Anker PowerLine+ USB-C to USB-A cable available for just $9.49. This is down from its regular price of $14.99, and this is also for the 6-foot long, braided cable, which makes it definitely worth the price.
This cable from Anker is available in black, and it is a braided cable. Which makes it great for traveling with, as it is very likely to never get damaged or broken. And that is definitely a good thing. This one is also about 6-feet long, which makes it great for traveling as well, as you never know when you'll need a longer cable, so it's always good to have one available just in case. This will work for any USB-C device, like a smartphone, a tablet, a laptop or even a gaming console like the Nintendo Switch.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap next-day shipping if you need it here extra fast.
