Xtar VC4 Charger
The Xtar VC4 Charger will effectively auto-adjust the charging current based on the cells chemistry or condition. This charger is capable of charging two cells at 1A or four cells at 0.5A. This is a safety feature – and helps protect excessive heat build and prolong the life of the cells.
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.
This charger is capable of charging two cells at 1A and is compatible with the new 20700 & 21700 formats (see below for more compatible formats).
