Hidden in a compact case is a fully professional processor charger with a three-stage charging process TC/CC/CV. It charges 1-2 Li-ion cells 3.6 / 3.7V of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700. It is also possible to charge a single battery in sizes 20700, 21700, 25500, 26500.

What is the TC/CC/CV charging method? It is a three-stage process for charging Li-ion cells that ensures the cell remains 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 2.85V are 'woken up' with a lower current.
- CC Phase: after reaching 2.85V, the cell is charged with a constant current of 1A or 0.25A (depending on the power source used).
- CV Phase: when the cell is almost fully charged, the charger switches to charging with a decreasing current until a voltage of 4.2V is reached on the cell. Once 4.2V is reached, the charging process is complete - the battery is fully charged.
Batteries with a voltage of 4.1V or higher are treated by the charger as charged. To top up such a battery to full, it must be placed in the charger before turning it on. Batteries left in the charger that are charged will undergo a natural self-discharge process. Charging will resume when the voltage on the battery drops below 4.1V.

The Xtar MC2 charger has the function of reactivating deeply discharged cells and cells with a voltage of 0V. Many chargers on the market are unable to charge such batteries. Here, the Xtar MC2 charger comes to the rescue, which in many cases allows for the 'rescue' of such cells. Just insert the deeply discharged battery into the MC2 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 suffer irreversible damage and their reactivation may be impossible. It is important to avoid excessively deep discharging of Li-ion batteries - this can lead to a significant reduction in their lifespan and capacity or cause them to become completely inoperative.
Chargers from other manufacturers can significantly raise the temperature of the charged cells during charging. Excessive heating of the cells can lead to faster wear. In designing the MC2 charger, Xtar took a step further than the competition by solving this problem in a simple way: an external power supply was used. As a result, the temperature of the battery being charged in the MC2 will rise by no more than 15 degrees.


Included with the Xtar MC2 charger is a USB-C cable. The power adapter is not included in the set. To power the charger, any charger with a USB-C cable, such as from a phone, or a USB socket or a computer with a free USB port will suffice. The recommended charger power is 1A (1000mA).
