What's so weird about it? There's a massive business of external batteries in the mobile space that do effectively the same thing. What does Mophie know that OWC doesn't?

Doesn't the mophie have its own charging port? I think it's weird because the external battery would need to know to only charge when the host Macbook Pro is charging, otherwise it's draining the Macbook Pro's battery to backup the battery it's draining.

  What's stopping OWC from including a charging port that does just this while sending a message to the MBP that it's plugged in? That's effectively what all those external batteries do. We're discussing a theoretical change to a device that isn't on the market yet.

    >> What's stopping OWC from including a charging port that does just this while sending a message to the MBP that it's plugged in? Nothing is. But it would be weird to do so with the base having only one USB-C port. The more common expectation is that there would be a pass-through USB-C port. >> That's effectively what all those external batteries do. I've always been under the assumption that all the external batteries have their own circuitry to take power from its incoming port and send power (either passing through AC or from its battery) to the outgoing port when the host device demands it. I was not aware that the outgoing port on all those external batteries also got power from the host devices, so I guess I learned something today. >> We're discussing a theoretical change to a device that isn't on the market yet. Going back to my original comment, I just made an observation that it would be weird for the product ---as shown in the photos--- to use that one port to charge itself and to charge the Mac. Most products I know use a pass through. That's it. I did not suggest a theoretical change to the device. --edit - by "charge itself" I mean in the case where it did have a battery
