!! NEW VERSION WITH A CHANGED SOCKET TO USB-C!!
Hidden in the small casing is a fully professional processor charger with a three-stage TC/CC/CV charging process. Charges 1-2 Li-ion 3.6/3.7V cells of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700. It is also possible to charge one battery size 20700, 21700 - only unprotected, 25500, 26500.
What is the TC/CC/CV loading method? It is a three-stage charging process for Li-ion cells that ensures that the cell is kept in good condition by charging with the right current at each stage and completing the charging process at the right time.
The different steps 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 0.5A or 0.25A (depending on the power source used).
- CV phase: when the cell is almost charged, the charger switches to charging with decreasing current until the voltage of 4.2V on the cell is reached. 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 as charged by the charger. To fully charge such a battery, insert it into the charger before turning it on. Charged batteries left in the charger will undergo a natural self-discharge process. Charging will resume when the battery voltage 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 not able to charge such batteries. This is where the Xtar MC2 charger comes to the rescue, which in many cases allows you to 'rescue' such cells. Simply insert a deeply discharged battery into the MC2 charger as you would with normal charging - the charger will detect the discharged battery and attempt to reactivate it.
Remark! Cells discharged below a certain level are irreversibly damaged and may not be able to reactivate. Avoid discharging Li-ion batteries too deeply - this can lead to a significant reduction in their durability and capacity or lead to their complete inefficiency.
Chargers from other manufacturers can significantly increase the temperature of the charged cells during charging. Too hot cells can cause them to wear out faster. With the MC2, Xtar has gone one step further from the competition by solving this problem in a simple way: using power from an external power supply. Thanks to this, the temperature of the battery charged in the MC2 will increase by no more than 15 degrees
The Xtar MC2 charger comes with a micro USB cable and a cover to protect the charger during transport. A power adapter is not included. To power the charger, all you need is any charger with a micro USB cable, e.g. from a phone, or a USB socket, or a computer with a free USB port. The recommended power of the charger is 1A (1000mA).
