What's the longevity like on these micro usb ports? My evo is on and off a charger a lot!
Fwiw, i believe you can mix and match usb cables and chargers at will. The whole point of using a standard like that is that they're interchangeable. Ferrite core just reduces noise, which doesnt impact dc charging at all. In theory, it might affect data transfer, but I'd be surprised.
Cables are an insanely high profit-margin item. Tons of vendors are thrilled to sell gold-plated, flat-braided, nitrogen-impregnated, snake-oil saturated whatever, but basically, it just needs to make an electrical circuit.
