Charging speed is driven primarily by the charger and device’s battery. A “fast-charging cable” is simply one that’s rated to safely carry the higher voltages and amperages that fast chargers employ. That usually means the “fast” cables have somewhat heavier-gauge internal wires and insulation than standard cables. <\/p>\n\n\n\n

But a fast-charge-capable cable does not require<\/strong><\/em> a fast charger. Wires are wires, and a fast-charge-capable cable will work fine with lower-rated (e.g. non-‘fast’) chargers and devices, too — albeit with no speed up. <\/p>\n\n\n\n
