content: A standard USB-C to USB-C cable will already do this -- in Android, when USB-C is plugged in, a notification appears allowing you to make your phoneprovidepower. And if the other end were adapted into an Apple device, I'm sure that'd work.So what is this new cable actually doing, that isn't already supported?

content: Interesting idea I suppose, but isin't it much easier to just have a battery bank? If you're in that situation you may not want to actually drain power from another device.

content: Quote from: rs20 on November 02, 2016, 11:33:40 pmJust that you do not find a micro-micro USB cable with one end that has its ID pin grounded and the other not off the shelf yet.Quote from: Red Squirrel on November 02, 2016, 11:44:33 pmFor when you don't have one I guess? But given you have to have the cable it's kinda pointless.

content: Yes, but that is the OTG feature. Phones already have that. I don't understand why there is a product that does exact same thing that phones already do by default? Or maybe you don't get OTG cable when you buy such a phone? But even then, why is it adertised as some invetnion?

content: Quote from: Srbel on November 04, 2016, 06:19:26 amNormally a USB OTG cable (which normally doesn't come with the phone because 99% of users never plug anything other than headphones into their phone) terminates in a female USB socket; so that it "looks like" a computer -- i.e. you can plug a normal USB keyboard or mouse into it, and the phone will recognise it.You could plug a normal USB charger cable into this, and then those two cables together would perform the same task as this PowerMe thing. The ostensible advantage of the PowerMe thing appears to be that it's a single cable, not a cobbling-together of two different cables.
