Re: Does charge cord length effect Mintyboost efficiency?
Normally, off the shelf USB cables are pretty well shielded from stray inductance. What may ultimately reduce charge efficiency is the number of contacts across the circuit and the gauge of wire used, every connector to connector interface contributes to resistance, and corrosion on those contacts increase series resistance. There should be negligent effects between using a 3ft cord and a 6ft cord as far as charging is concerned. If data is transferred across those data lines, it may become more of a factor above 6ft, but in terms of a power reference bias I wouldn't worry about it.
