Battery Charging Speed at Monica Baker blog

Battery Charging Speed. A basic usb port sends 2.5w to the connected device, and faster chargers raise this amount. It seems like every new phone promises faster charging, but what do the different charging technologies mean, and are they equally. At the most basic level, fast charging is simply increasing the number of watts (w) that are delivered to a phone's battery. To get the charging power (in watts) you multiply the current (in amps) by the voltage, which is almost certainly going to always be 20v. (9566 / 10,000) * 20v = 19.1w. Today’s fast charging smartphones range anywhere between 18w to 120w worth of power, with charge times ranging from 20 minutes to just over an hour. A typical slow charger delivers around 5v/1a (5 watts) of power, which translates to charging speeds of about 1% of battery capacity per minute. For example, a smartphone with a 3000mah battery might take approximately 3 hours to charge from 0% to 100% using a slow charger.
