    Haven't seen anywhere what the voltage is on watch battery. Can the watch be charged using iPhone charger? Description shows magnetic cable and usb extension cable but what about actual charger? Anyone know?

    It uses inductive charging (wireless) attached to the back.

    One end looks like this and the other end should be the same as the iphone Cube.

    The unboxing videos show the same adapter as the phone. The small cube. That you plug the cable into

    Can your apple watch charge without the magnet charger being attached to it and plugged into a wall? No. therefore. not wireless.

    So you are saying there is no such thing as wireless charging since there has to be a wire somewhere involved?:eek::D

    I'm sure you guys have heard about these two companies trying to come out with wearable battery straps for the :apple:WATCH.

    This was announced just over a month ago on 9to5Mac: http://9to5mac.com/2015/03/06/apple-watch-charging-strap/ The Reserve Strap is being offered as a preorder for a whopping $249, but it's a little iffy, since they have no firm release date or a price point. MacRumors also posted about it and has a small discussion as well here: http://forums.macrumors.com/showthread.php?t=1852733

    More recently, Macworld has this article: http://www.macworld.com/article/290...ack-guaranteed-to-kill-the-watchs-appeal.html of a company company offering preorders for the Wipowerband (ugly name) for $89 and $99 for the 38mm and 42mm models, respectively. They estimate a delivery date range between May and June.

    The industry refers to it as inductive or wireless charging because electromagnetic wave are used between the device and the charging dock, pad or mat. You do't have to connect any wires to the device. Of course from dock or mat back to the wall outlet is wired.

    The reason you attach the wire loop to the back is so the efficiency of the wireless charging is reasonable. There is a wire loop in the end of the charger that radiates a signal. This signal causes "like" signal or appear in a loop inside the watch. Charge is scavenged from the "like" signal to charge the watch.

    For this to work in a reasonable time frame, they want a very good "match" between the two wire loops.

    Thanks. My assumption is most here are not engineers.

    Sorry, but please learn the meaning of wireless charging before you make ridiculous statement such as that.

    Here is a pretty clear definition:

    'Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.'

    Speaking of charging .... did they mention how much time a full charge takes ?

    2.5 hours.

    Also, are you guys going to completely drain the battery on the first use? Then charge to 100%? Or does that stuff not even matter.

    That is what I want to know. They just say overnight but does that mean 6 hours gives you 80%, 60%, ?

    I'm not an engineer. I appreciated the layman terms explanation.

    No, they're actually very specific about charge times.

    Around 1.5 hours to 80%

    Around 2.5 hours to 100%

    That's awesome and grabbing some charge during the day seems possible to me now.

    2.5 hrs for 100%, I can live with that

    It is wireless by using inductive charging. No wire directly plugs into the watch
