This is a real pogo charging cable that you may connect it to a charger. This accessory will be for sale within next 10 days on eBay and amazon. I will post a link to buy when it is up online. Thank you.
cause it's probably just the cable portion with usb at the other end to plug into a usb wall wart. so it could do double duty with speakers and such that have usb inputIf it's just a charger, why does it have all the pins?
What's the point? I mean I already have a charger right, so why would I want this?

If its a gadget I want one!

I thought the rumor was that it was a separate charging circuit. That the USB wasn't drawing the full amperage...could be wrong.I hope its not just plugging into a USB wallwart, otherwise it won't charge any faster as it will be the same 2.1 amps. I want it to have it's own wallwart with about 5 or more amps. My NewTrent 9900mha battery pack charger has its own wallwart that charges it in about 2 hours. That's what we need for our N10's. Otherwise, I don't see a need for it unless you need to charge while using a USB OTG cable. In addition, I won't be able to charge with it while using my case in propped up configuration or while closed. What we really need is a dock with pogo pin charging. But, seeing how long it took to get the N7 dock, well.....
USB is limited in charging because its a standard. You could make a USB cord charge faster but it might destroy other devices if they get plugged into it. That is why Motorola went with a dedicated charging cord on the OG Xoom, fast charging and you can't accidentally destroy other devices. personally I don't know what the pins on the N10 do, so it might use more then 2 for charging hence the extra pins on the pogo charger in the OP. However I think its going to be a combination of 2 things, first more then 2 pins are used for charging (2 hot 1 neutral) and two the other end of that cord is a USB so it can plug into other things like docks and be able to send multimedia via the cable.
Just my guess though. It could also be a manufacturing thing. Its easier to make 1 cord end with all the pins then then multiple diffent ends with or without all the pins. Why build multiple machines for god knows how much money when you can just use one and have pins that don't do anything....
Sorry but that doesn't sound right to me.
A device (like an N7) will draw what ever current it wants. Having 5 Amps available to a 2 Amp device will not hurt it. The microUSB charging port is limited by the amount of surface area for contact and, potentially, by the gauge of the wires. This is why faster chargers use something like a barrel jack with lots of surface area. My guess is that multiple pogo pins are used for ground and +5V. As for the USB standard - the current limitation is from a USB port on a computer. USB 2.0 has a standard 100 mA available with a negotiation for 500 mA. USB 3.0 allows a higher current (900 mA) but still requires negotiation for it. This has nothing to do with stand alone chargers.which don't have any of that negotiation . Some do put voltages on the D+ and D- pins to signal what they are capable of delivering (though I believe only Apple devices look at that). Some USB chargers have current limiting so a 2 Amp device doesn't kill a 1 Amp charger though I wouldn't be surprised if cheap chargers don't.
