    In extremis - charging with a 5V charger

    OK so we know that you need special chargers and cables for the TF. I'm driven to distraction by tales of malfunctioning chargers etc on this forum.
    As a result I bought myself a charger which works at 12V see http://www.transformerforums.com/for...adapter-5.html , this works fine.

    Still paranoid I checked out my "normal" HTC Desire charger which pushes out 5V but at 2A
    Results - just the tablet, not the dock, (of course, unfortunately the cable is still needed, anyone found an alternative yet?)
    Starting at 52% charge, it increased to 77% in 3 hours - so when the tablet starts at a fairly low charge level it will charge at over 8% an hour.
    I find this quite encouraging, if the TF was nearly devoid of battery power I could get to 65%, at least, overnight (8hrs)
    I would therefore be happy to use the HTC charger away from home unless it was very rainy outside and I needed to use the TF a LOT (have to remember that damned cable though)


    btw does anyone else think Asus are crazy, or irresponsible, producing chargers which could push 12 volts into 5V devices via a "normal" USB cable? If they must have a custom cable, then they should at least make the charger end different.

    This is probably why you can actually feel the electronic shocks shooting thru your fingers when you are charging the keyboard and the Transformer and using it at the same time. It feels kinds cool but there is no way in the world that it should have ever passed the electrical tests to be approved for sale!

    At the same time, it is nice that it does charge more rapidly. It charges much faster than the iPad2 with its special charger. I can fully charge my dock and tablet in less time than my wife's iPad 2. Also, it is more energy efficient to use higher voltages. I do wish that the dock had come with a charger of its own for a backup.

    Now this is interesting... I had the same issue with my Macbook Pro. It actually felt like static electricity when I touched my MB.
    The issue was a faulty ground. I found this quite by accident when I plugged in a power strip that had a red and green indicator (green for ground, red no ground). I found the green ground wire in the wall plug was loose and when tightened, the problem went away... Just an FYI
