Say, 5AH*3.7V/10 Watts = 1.85 hrs. Last edited: Mar 27, 2019. Calculations of volts, amps, watts, and power are easily explained using Ohms Law. Your reply does not answer his question. A PC USB charger delivers 2.5 Watts of power (5 volts at 500 mA). The 10W charger is what it is supposed to use and would be much better, though. Good to know that the iPhone 5 won't take more than 1A. Therefore the max load is 5v x 0.5A=2.5. All consumer phones charge off 5V. And based on what I saw from Apple for their new Macbook, the charger is 29W, so most likely a Profile 3 (a bit under spec), it seems then to be only 12V. The standard for most GoPros is 5V/1A. So 18W is 3.6A at 5V and 30W is 6A at 5V. An iPhone charger delivers 5 Watts (5 volts at 1000 mA). 1.5A: 5V: 7.5W: USB Hubs. The output one is 5V/1A and the other one is 5V/2.1A.
