Hidden in a small casing is a fully professional processor charger with a three-stage charging process TC/CC/CV. It charges Li-ion cells 3.8 / 3.85V of any capacity in sizes 16650 / 18650.

What is the TC/CC/CV charging method? It is a three-stage charging process for Li-ion cells that ensures the cell is kept in good condition by charging with the appropriate current at each stage and completing the charging process at the right moment.
The individual stages of the TC/CC/CV process are:

• TC Phase: cells discharged below 2.9V are 'woken up' with a lower current.
• CC Phase: after reaching 2.9V, the cell is charged with a constant current of 0.7A.
• CV Phase: when the cell is almost charged, the charger switches to charging with a decreasing current until the voltage of 4.35V is reached on the cell. After reaching 4.35V, the charging process is complete - the battery is fully charged.

The Xtar EC1 charger has a reactivation function for deeply discharged cells and cells with a voltage of 0V. Many chargers on the market are unable to charge such batteries. Here, the Xtar EC1 charger comes to the rescue, which in many cases allows for the 'rescue' of such cells. Just insert the deeply discharged battery into the EC1 charger, just like with normal charging - the charger will detect the discharged cell and attempt to reactivate it. Note! Cells discharged below a certain level may suffer irreversible damage and their reactivation may be impossible. It is advisable to avoid overly deep discharging of Li-ion batteries - this can lead to a significant reduction in their lifespan and capacity or render them completely inoperative.

Chargers from other manufacturers can significantly raise the temperature of the charged cells during charging. Excessive heating of the cells can cause them to wear out faster. In designing the EC1 charger, Xtar has gone a step further than the competition, solving this problem in a simple way: it uses power from an external power supply. As a result, the temperature of the battery charged in the EC1 will rise by no more than 15 degrees.

Included with the Xtar EC1 charger is a micro USB cable. The power adapter is not included in the set. To power the charger, any charger with a micro USB cable, e.g., from a phone, or a USB socket or a computer with a free USB port is sufficient. The recommended minimum power of the charger is 0.7A (700mA).
