What is 5000 mAh in amps? Converting mAh to amps involves dividing by time. 5000 mAh is 5 amps (5000 / 1000). How many volts is 10 milliamps? Volts can’t be directly converted from milliamps without resistance information. If resistance is around 100 ohms, 10 mA might result in 1 volt (V = I * R).
Brick’s power bank energy: 5000mAh *3.7V = 18.5 Watt-hours; iPhone battery cell energy: 2815mAh * 3.7V = 10.4 Watt-hours; Efficient coefficient: input * output => 0.85*0.85 = 0.7225; Charges: 18.5/10.4 * 0.7225 = ~1.3 times; A Brick power bank will fully charge an iPhone 12 approximately 1.3 times.
