Wireless charging explained: What is it and how does it work?

Computerworld:

Wireless charging technology has been around for more than 100 years, but its inclusion in devices such as Apple’s new iPhone line has given it new life. Here’s how it works, and why it could soon show up in everything from homes to robots.

Another good explanation of what the future holds for many of our devices and gadgets.

    Well, for one thing, it’s not wireless.

      Says who?

      • JimCracky

        Induction coils are not wireless charging. As long as contact has to be made to the charger, it is not wireless.

        • GlennC777

          Induction doesn’t require contact, and there is no wire between the device and the charger.

          It may not be long-range wireless charging, but I say it’s fair to call it wireless.

            Having to sit it right on top of something that’s plugged into the wall doesn’t feel like wireless charging. It’s barely different than a dock.

          • GlennC777

            Maybe not a huge difference, but my point is just that the charging itself is indeed absolutely wireless and it’s perfectly fair to call it that.

          • Billy Razzle

            Technically you may be right. However, having the iPhone sitting 4 inches from the wire isn’t really “wireless” in practice. It’s more like “wire adjacent” charging.

          • GlennC777

            Absolutely. “Wireless,” yes, “remote,” no.

            Remote would be nice, but that’s a different distinction.
