Handheld Portable Charger XTAR PB2 ORANGE 18650

XTAR PB2 to 18650 USB Li-ION charger 2 channels ORANGE

The revolution of the traditional charger with power bank function!

Extremely useful and functional device. Compact and lightweight design in a soft-touch case (scratch-resistant material), can be used simultaneously as a charger and Power Bank. Charges one or two unprotected Li-ION 18650 batteries at the same time. Features 0V technology , reactivating deeply discharged cells (while charging). Supports high-capacity cells (3400mAh) that give more power. Has a charging function management system. Compatible with industrial cells (so-called without high plus).

When using the Power Bank and charger at the same time, both functions work independently at the same time and safely complete the charging processes.

The Power Bank function is fast, and with a maximum charging current of 2.1A with powerful 18650 Li-ION cells, it gives you the ability to charge 2 full cell phones or a tablet. It is safe thanks to protection against reverse polarity, short circuit or overheating.

Used as a Power Bank:

• 2.1A USB output (fully charges an Iphone 7 Plus in 2 hours)
• Protects the environment by supporting rechargeable cells
• Controls cell charging and has a Power Bank capacity of up to 7000mAh
• Charging and discharging balancing technology makes the entire capacity of the cell available and further increases its lifespan
• Conversion efficiency of up to 92%
• Portable Power Bank with magnetic case closure, quickly charging all kinds of cell phones and USB devices

The small size and features of the charger make it a handy device not only for traveling. It has an easy-to-read LED display, indicating the level of charge (as a charger) or discharge (as a Power Bank), of batteries. The rubberized shell of the case and magnets used to hold the slot cover, allow you to change batteries very quickly.

Used as a battery charger:

• Maximum actual charging current 2A with one cell or 1A with 2 cells
• Capable of fully charging a 2500mAh battery in 1.5 hours or 2 x 2500mAh 18650 batteries in 3 hours
• Equipped with 0V activation function to revive over-discharged batteries
• Three-stage TC / CC / CV charging maximizes battery life
• Features multiple safety features

USB output function:

• The USB output allows you to charge both batteries and external devices at the same time when the power is connected.
• While the charger becomes a Power Bank, the display shows the percentage of battery/batteries discharged.
• The charger prioritizes charging devices connected to the USB output. Once the USB charging process is complete, it starts charging the cells inside it with full efficiency.
• Charging from the USB outlet is directly directed from the connected charger's power source, bypassing the use of cells, thus reducing their consumption.
  

Technology used:

• With optional charging currents of 1.0A and 2.0A, you can control the charging speed and thus extend battery life.
• Li-ION cell charging method, processor-based TC/CC/CV.
• Cut off charging at exactly 4.2V when the battery is fully charged
• Each channel is independent, so 1 or 2 Li-ION cells can be charged at the same time
  
• Buffer technology protects the batteries during the charging process
  
• Thermal, short circuit, reverse battery insertion protection
• 0V reactivation of deeply discharged batteries
• Rubberized housing shell
• 12-month warranty

The TC/CC/CV charging algorithm used in the charger is a charging process for Li-ION cells to ensure good cell condition. It involves charging with the right current and also completing the charge at the right time. TC/CC/CV charging stages, we can divide into:

• TC stage: the initial phase of checking and reactivating a cell whose voltage has dropped below 2.9V
  
• CC stage: then the cell is charged with a constant current of 50mA to 500mA (depending on the connected power source).
• CV stage: then the charger switches to charging with decreasing current until the cell voltage reaches 4.2V. When the cell voltage reaches 4.2V, charging is complete and the battery is fully charged.

Reactivating discharged cells involves inserting the cell into the charger and checking the voltage. With this function, we can check each cell in the appropriate size. When a discharged cell is detected, the charger will attempt to reactivate it. Note that exceeding the minimum voltage on the cell will limit the possibility of reactivating and saving such a battery. When you leave the cell in the charger it will self-discharge. However, if the voltage on the battery drops below 3.9V for Li-ION, charging will start automatically.

An interesting and safe solution in the PB2 charger is a separately connected power supply. This prevents unnecessary heating of the charged cell. The temperature on the cell, can rise no more than 15ºC. When the set is working, the power supply itself heats up and not the charged cell. This directly affects the life of the battery.
