USB TYPE-C VS WIRELESS

Mobile devices such as the Apple watch already use a wireless charger. The supplied charger plugs into a USB Type-A port and this works fairly well.

Over in the EU regulators are pressuring the industry to reduce the number of connectors in use. They are pointing to a growing amount of garbage that could be reduced with standardization. This has led to a smaller number of connectors in use and eventually USB Type-C has been designed for universal use.

Some mobile phones are now using USB Type-C for charging. The MacBook here also used Type-C for charging. The iPhone and iPad use Apple’s lightning connector. Apple may adopt Type-C across the line primarily to support more power while offering more bandwidth.

The best wireless chargers now available reach 18W while the biggest Apple USB Type-C charger is 96W. The Apple charger could support a wide number of devices.

USB moved to the smaller reversible connector primarily to be able thinner devices. The improved speed now reached 40 gigabit speeds which is fast enough for interfacing to a fiber based network.

Wireless seems to be best for a watch and a phone. The tablet with the much larger battery may be better served with more power. The iPad Pro can charge the Apple pencil which is used as a pointing device.

The outlook seems that USB Type-A will continue to be used for years to come due to the large installed base. Type-C is best seen beside Type-A. The front panel box for the desktop machine has both Type-A and Type-C which is probably the best solution for a decade or more.
