Using a power input which is 9V/2A:
1) The charging speed is 1200mA if you charge one battery.
2) The charging speed is 800mA of each battery if you charge two batteries at the same time.
Using a power input which is 5V/2A:
1) The charging speed is 1000mA if you charge a battery。
2) The charging speed is still 1000mA if you charge two batteries, but the charger will charge the first insert of the battery first, and then it will charge the second insert of the battery after fully charged the first battery.
