Charging times are variable based on flow rates and size of the battery that you are charging. As an example, charging an iPhone 7 (2900 mAh battery) with a flow rate of 2.2 mph (3.5 km/h) would take approximately 2.3 hours to charge from 0-100%. A flow rate of 1.8 mph (2.9 km/h) would take approximately 4.5 hours to charge the same battery.

For more information on charging times and flow rates please refer to the "Tech Specs" section on each product page.
