There's another thread here where I learned something new about voltage drop. I usually think of it in higher voltage, such as generator runs, but it turns out you can have significant voltage drop in 5 volt over just 3 feet if the gauge of the wire is not sufficient. As I recall, you should have 24 gauge wire, where many USB cables are 28 gauge.

Anyway, not terribly up on battery charging, but I would suspect a voltage drop would significantly impact charging times.
