(Answer requested by Rosario Mezzatesta)<\/small><\/em><\/p>\n\n\n\n

If the cables are designed properly, yes.<\/p>\n\n\n\n

However, if either cable’s internal conductors are too thin, energy will be lost as resistive heat along the way; this can make the charging time longer. And: The longer the wire, the greater the thin-wire-resistance effect.<\/p>\n\n\n\n

Very long power cables need substantially thicker conductors to counter the inevitable losses and to deliver charge at the same rate as short cables.<\/p>\n\n\n\n

But, in general, if you use good-quality cables in the shortest length that’s reasonable for your circumstances (I mean, a 10 meter charging cable is<\/strong><\/em> pretty extreme!), there’ll be negligible effect on charging time.<\/p>\n\n\n\n

(OK, if you want to get really<\/strong><\/em> persnickety, each additional foot or so — about 0.3 meter — of length adds about a nanosecond of energy transit time through the wire. So there’s also that. \ud83d\ude42 )<\/p>\n\n\n\n
