How Long Does It Take To Charge A Battery?
Most Modern Devices With Built-In Batteries Indicate The Current Charging Status Of The Battery On A Display Or Status Leds. The Charging Process Is Also Automatically Terminated By The Internal Charger Of The Smartphone Or Tablet, Etc., As Soon As The Battery Is Full.

Nevertheless, It Is Helpful To Know How Long A Full Charge Theoretically Takes With An Empty Battery. This Is The Only Way To Choose The Right Solar Panel Model For The Requirements Of The Devices You Want To Charge.

Here Is A Short Calculation: Divide The Capacity Of The Battery (Mah) By The Charging Current Of The Charger (Ma) And Multiply This By A Factor Of 75. This Then Gives You The Approximate Charging Time In Minutes That Is Required To Fully Charge The Battery At 100% Sunshine Duration.
Example: A Battery With A Capacity Of 3000Mah (3.0 Ah) And A Charging Current Via 5 Volt Usb Connection Of 3100Ma (3.1 Amps). So 3000 : 3100 X 75 = 73 Minutes. Dividing The Result By 60 Gives The Charging Time In Hours: 1.2 Hours.
This Means That An Average Smartphone Can Be Fully Charged In Just About 1.2 Hours With A 40-Watt Solar Panel.
