I did a second test this time with a 1100mAh battery. I think this might help explain why some people seem to have more problems then others. The 1100mAh battery has a much lower charging current then the 2200mAh battery.
The charging started at 630mA and remained flat for most of the charging. I was watching the data from time to time and was able to notice when the current started to go down and turned on the axim to check the battery %. I found that it happened around 67% so I expect if you really want to use one of these cables and use a computer USB port you should have no problems at all if you leave the axim off, have a 1100mAh battery in it and the battery is at 70% or more
I still hope to post some pictures so you can see the power curve but this data should give you some idea of what kind of power you need. But if your having problems and are using a 2200mAh battery I recommend you try out the 1100mAh battery.
