I doubt using anything more than a 3A power supply will increase charge times (unless your 3A power supply isn't really giving you 3A), as the lithium charger IC is limited to 3A input current to protect the power supply. The charge management IC is capable of a maximum of 4A charge current, although I'm not quite sure what charge rate it is set to - I'd suspect a just a little below 3A since the calculation looks basically the same, and the configuration resistor values are only marginally different.
