This charger will effectively auto-adjust the charging current based on the cells chemistry or condition. You may find that cells are also charged at 0.5A initially and then increased to 1A mid way through the charge. This is a safety feature - and helps protect excessive heat build and prolong the life of the cells.
This charger is capable of charging two cells at 1A and is compatible with the new 20700 & 21700 formats.
A mAh readout function allows you to inspect the current condition of fully charged cells. However, it is worth noting this function only calculates what is added to a cell, and not what is already on the cell - to get a more accurate reading, cells should be fully depleted, then fully recharged.
