The Anker KVM Switch (For Desktop and Laptop) is now available via Amazon in countries in North America and Europe. The two host devices connect to the accessory via USB-A inputs. These are accompanied by other USB-C and USB-A ports that can be used for file transfers and charging devices.
Seems like a great price for a KVM. Last I looked (granted, circa covid era), KVMs were multiple 100s
It’s not a KVM though, which is why it’s only $50. It has no video capability.
