How much can the E-SPARK charge my phone?Updated 2 years ago

The E-SPARK has a battery capacity of about 800mAh. To prevent damage to the internal battery, you can use about 500mAh of that capacity to charge other devices. This results in about 10-15% battery charge added to your mobile phone, depending on the model and its battery capacity.

This estimation was made by charging a mobile phone with a battery capacity of 4500mAh in a controlled environment. Actual results fluctuate depending on multiple factors including the model and charging efficiency of your phone.
