Because they're sending more power through. I know this is a rather poor explanation, but it's the simple truth. The voltages are always the same, but the Amperage is higher which means that more power courses through the cable per second.

The Short Answer

Because they're sending more power through. I know this is a rather poor explanation, but it's the simple truth. The voltages are always the same, but the Amperage is higher which means that more power courses through the cable per second. All batteries have an inherent safe-amperage for charging, but it's often higher than the charger is actually sending. (likely for safety reasons)
