For charging the battery (Ring doorbell 2), would a 2.4A usb charger make a difference over the 2.1?

From: [https://support.ring.com/hc/en-us/articles/115003012526-Charging-the-Battery-on-Your-Ring-Video-Doorbell-2](https://support.ring.com/hc/en-us/articles/115003012526-Charging-the-Battery-on-Your-Ring-Video-Doorbell-2) "Your Ring Video Doorbell will take around five hours to fully charge when connected to a 2.1-amp charger (usually marked 2.1a) and around ten hours when connected to a 1-amp charger (usually marked 1.0a)." 2.1Amp 5hrs 1Amp 10hrs 2.4Amps? Would that do anything (charge slightly quicker)? If not, would it possibly damage the battery? I am asking because I would like to make a decision on whether to purchase a 3rd-party 2.1 or 2.4Amp charger for my doorbell. Thank you.
