  14. A***a

    The converter continued to produce stable 5 volts (5.08) when charging the phone at a battery voltage of about 3 v. Can be cut off at a voltage of 2,8 volts or lower, then sucks the capacity almost to the end, while the display has long been worth 0% and it is able to charge yet One phone, used panasonic batteries green without protection, with protection do not fit, the capacity of one 3400, 5 pieces total 17000 mah, with the efficiency of the converter 80% receive 13600 Mah This is the maximum that will be from this power bank, but it is necessary to take into account the limitations on the voltage of the converter, because it will be cut off before the batteries give full capacity, with these assumptions we will get somewhere 3000 per jar and about 12000 mah at the output, But even under the worst conditions, we are guaranteed to get 10000 + mah which over time will not lose their capacity, as the batteries are proven and reliable enough.
