VC2 is a professional processor charger with a three-stage TC/CC/CV charging process and LCD display. It charges 1-2 3.6/3.7V Li-ion cells of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 22650, 25500, 26650.

The backlit LCD display of the Xtar VC2 charger shows real-time information about the operating status of the charger: the voltage of the batteries to be charged, the charging current, the charge used to charge the cells, indicates any errors and informs you that the charging is complete. The information about the used charge can be used to measure the capacity of the batteries. To measure the capacity of the battery, it should be discharged to the appropriate voltage cut-off level (usually 2.5V) and inserted into the VC2 charger. When charging is complete, the display can read the value of the charge used to charge the battery. This will always be 3-5% higher than the actual battery capacity. This is due to the fact that the battery charging process is never 100% efficient, i.e. a slightly larger charge is needed to charge the battery than the actual capacity of the cell.

What is the TC/CC/CV charging method? It is a three-stage process of charging Li-ion cells to ensure 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 individual steps of the TC/CC/CV process are:
•TC phase: Cells discharged below 2.9V are 'woken up' with a lower current.
•CC phase: When 2.9V is reached, the cell is charged with a constant current of 0.05A to 0.5A (depending on the power source used).
•CV phase: when the cell is almost charged, the charger switches to decreasing current charging until the voltage of 4.2V is reached on the cell. When 4.2V is reached, the charging process is complete - the battery is fully charged.

Charged batteries left in the charger will undergo a natural process of self-discharge. Charging will resume when the voltage on the battery drops below 3.9V.

The Xtar VC2 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 VC2 charger comes to the rescue, which in many cases allows you to 'save' such cells. Simply insert the deeply discharged battery into the VC2 charger as you would with normal charging - the charger will detect the discharged cell and attempt to reactivate it. Remark! Cells discharged below a certain level are irreparably damaged and may not be able to reactivate them. Avoid discharging Li-ion batteries too deeply – this can lead to a significant reduction in their lifespan and capacity, or lead to their complete inoperability.

The Xtar VC2 charger comes with a micro USB cable and a cover to protect the charger for transport. A 2100mA power supply is included.

Micro USB mains charger with a power of 2100 mA. It allows you to charge most phones, mp3/mp4 players, and other devices charged via the micro USB port.

Thanks to the 1.4m long cable, it is perfect for home and office conditions, where the standard length cable turns out to be too short. It has overcharge and overvoltage protection.

Specifications:
• Input voltage: 100-240V AC 50-60Hz
• Output voltage: 5V DC
• Maximum output current: 2100mA
• DCP/speed charge compliant: yes
• Plug type: micro USB
• Cable length: 1.4m

The charger complies with the DCP (dedicated charging port) standard for charging mobile devices, commonly called: "speed charge", "fast charge". DCP-compliant power supplies have pins that are normally used to transmit data. This procedure is needed so that new smartphones can detect the compatibility of the charger with the above-mentioned standard and be charged at the optimal current intended for them. Non-DCP chargers will charge most smartphones, but they will do so much slower. By buying our chargers, you can be sure that the devices will always be charged on time!
