USB type A (Male) to USB type C (Male)

Almost all the new smartphones come with micro USB C. By 2024 all new smartphones and tablets sold (within the European Union) will require a common (USB-C) charging port and Laptops by 2026.

USB-C can be inserted both ways making it easier to connect. Having a common port will help significantly reduce e-waste and make it easier for devices to be charged and connected.
