I assembled two mintyboost v3 kits, hoping to be able to charge mine and my wife's iPhone 4. It seems with both of them start charging, and then at some point the "Charging is not supported with this accessory" message comes up. Now obviously my first thought is that I've done something wrong somewhere, given that this is my first soldering project and also in light of this post: http://forums.adafruit.com/viewtopic.php?f=15&t=16791&p=84580&hilit=iphone+4#p84580
. Could someone give me some pointers as to what to do in terms of troubleshooting? The connections look good visually, but should I just try to re-work each one?
The voltage readout when I was assembling each one was a little on the low side (I think 4.93 and 4.97V if I remember correctly), but at the time I just thought this was within the error of the meter.
Any help greatly appreciated!
