Charging with wall adapter and USB extension.

[Menneisyys2]

Thats it. The "old" ipad charger is 10W which is 2A at 5V and the one for the Retina Displays is 12W Which is 2.4A at 5V. Then again, try to deliver a Low Voltage at a "high" ampere over a long distance. Without some tricks thats not possible without loosing too much mV on the distance. Here you see my extensions: http://youtu.be/E1NnJiNUl54 See how thick are the cables?

Yup, very few aftermarket cables are capable of recharging iPads at the full recharger capacity.

I'm continuously measuring (I'm an engineer) the Amperages of every single cable and adapter (e.g., the HDMI adapters - see the results at https://forums.macrumors.com/threads/1581053/ , in Section "1.4 Recharging") I run into and found out that very few of them do this.

I am Radio Television Engineer and Media technician. As we have these problems on stage quite often I developed and manufacture a charging cable. I got 5 meters and 10 meters. The cable is a heavy duty one for professional use and is only for charging. It does not provide any data functionality, but charging over 10m while the ipad is running works like a charme. Also instead of the original charger you can use any other stabilized charging device with 5V and at least 2A. Feel free to PM me for details.

Apparently as a new member I can't PM you yet. Is there a way for you to contact me and let me know how to order?
