Our charging stations charge up to 2.4A, which is the maximum amperage a phone can safely receive.
Charging times vary on device, how many apps are open, amongst other variables. The standard charger that comes with your phone from the factory is typically a 1A charging speed for example. You can expect at least double charging speeds than the factory charger.
Each device also has a regulator inside that determines how much power it would like to receive. A phone at 10% battery will charge faster than a phone with 80% battery.
