Product description: Charger for Li-Ion 18650 / 18700 / 20700 / 21700 batteries with PowerBank function - XTAR PB2S - red
Small size charger from Xtar with PowerBank function and three-stage charging process TC / CC / CV . It can charge two Li-Ion 3.6 V / 3.7 V cells of any capacity with markings 18650 / 18700 / 20700 / 21700 - without protection and 18650 with protection . Xtar PB2S does not significantly increase the temperature of the charged cells during operation, thanks to the use of power from an external source. The built-in numerical display shows the current voltage, charging current and percentage of the battery capacity. The parameters are displayed using the button on the side of the charger. The charger includes a USB type C cable, but no power supply is included . It is recommended to use a power supply with parameters 5 V / 2 A, which is compatible with QC 3.0 or PD 3.0. The charger has a red housing and a modern design. The charging chamber cover is magnetic, so it can be easily removed.
Attention!
Cells discharged below a certain level are irreversibly damaged and their reactivation may not be possible .
Charged batteries left in the charger will undergo a natural self-discharge process.
Key Features of the Xtar PB2S Charger for Li-Ion Batteries
- Xtar PB2S is designed to charge two Li-Ion cells of any capacity marked 18650 / 18700 / 20700 / 21700 - without protection and 18650 with protection .
- It features a three-stage TC / CC / CV charging process and automatically selects the optimal cell charging parameters.
- It has a function of reactivating deeply discharged cells.
- The clear numeric display shows the current voltage, charging current and percentage of battery capacity. The parameters can be easily viewed with a small button located next to the display.
- The charger has built-in short circuit, thermal and reverse polarity protection.
Charging Method TC / CC / CV
The method aims to keep the cell in good condition by charging with the right current at each stage and ending the charging process at the right time. The process is divided into three phases:
- TC phase : cells discharged below 2.9 V are "waked up" using a lower current.
- CC phase : after exceeding 2.9 V, the cell is charged with a constant current of 2 x 2 A / 2 x 1 A / 1 x 2 A.
- CV Phase : after the cell is almost fully charged, the charger switches to charging with a decreasing current until the voltage of 4.2 V is reached. After reaching the voltage of 4.2 V, the charging process is automatically completed.
In the battery accessories category you can find products such as discharge indicators and battery protective bags .
