I'm looking for a 6-10' USB extension cable that I can connect to the charger and the Lighting cable that will not give me 'unrecognized charger' errors and will not slow down charge speed. Any suggestions? The 3' factory cable is too short and using a power strip to extend isn't realistic. Being able to use a USB extension cable is the BEST solution, I just need to know one that will work perfectly as if it wasn't there (no iOS errors and no loss of charge power). Suggestions?
