"Charging is not supported with this accessory" for iPod touch 4g

by fowlernathaniele on Tue Jun 26, 2012 3:34 pm

I have the MintyBoost v3 and it works for many of my devices (Amazon Kindle, LG Octane [phone], Droid Razr [phone], etc). However, when I plug in my iPod touch 4th generation, it comes up with the "Charging is not supported with this accessory" message after charging for about .5 seconds. I have set up the MintyBoost in two ways; the first way is with no modifications (except a small 4v solar panel) and without the data lines shorted. The second way, which I prefer much more, involves a wire being attatched to each data line and then to a switch. The switch allows me to be able to choose whether I want the data lines to be shorted or not so I am not stuck one way or another. Voltages are also good across the board (4.98v for power, 1.96 for D1 and 1.97 for D2) so I do not believe that voltage is an issue. Any help would be great. If the pictures are not good enough/clear enough I will upload different ones (the origonal ones were humongous so I scaled them down).

K lets start from beginnings - use 2 AA batteries - fresh ones! No solar panel, and remove the wires from the data lines - does the iPod touch work>

Removed everything as you recommended...still giving me the same error message after about .5 seconds of charging. Maybe a glitch in the iPod? An iPhone 4S is working with it strangely, just not the iPod.

What's the iPod battery level at when you start charging?

The first time I tried, it was at about 95%. The second time it was about 50-60% and the third it was almost dead, so ~5%.

Does the output voltage of the mintyboost change significantly when you connect the phone?
What kind of batteries are you using?

I just tried again trying to test the voltage and it was working every time. I changed battery holders, so that might have something to do with it. At least it works now. Once I have it all back together the way that I had it before I'll post about it it still works.
