Charger XTAR OVER 4 SLIM 18650-26650 White

XTAR OVER 4 SLIM 18650-26650 Li-ION/IMR/INR/ICR charger, 2 channels, 2 x USB white

• Fastest charger ever max. 2 x 4.1A
  
• Can charge cells: 18650/ 18700/ 20700/ 21700/ 22650/ 26650, at 3.6V/3.7V nominal voltage - Li-ION technology
  
• The charger cannot charge protected Li-ION batteries in sizes: 20700 and 21700
• Countdown charging time for each channel separately
• Display of charging percentage from 0% to 100% and also information about voltage, resistance, current and temperature
• 0V Reactivation function can save "dead" batteries
• Compatible with cells, industrial (so called without high plus), and IMR/INR/ICR batteries
• Battery temperature and resistance testing with overheat protection
• Optional current for each socket 1A / 2A / 4.1A
  
• Dual USB port 5V / 2.4A
• Informative LCD screen
• Made of fireproof material
• Warranty: 24 months

• USB output allows you to charge both batteries and external devices at the same time when the power is connected
• Display shows charging status
  

Advanced technology:

• With optional charging currents of 1A / 2A / 4.1A , you can control the charging speed and thus extend the life of the cells.
• Li-ION cell charging method, processor-based TC/CC/CV.
  
• Each channel is independent
  
• Buffer technology protects the batteries during the charging process

• 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.

Smart LCD screen:

• Displays information on current and percentage of charge, as well as voltage, resistance and temperature
  
• Backlighting of the screen, will automatically go into power saving mode after 2 minutes of inactivity
  
• The status of the charger is determined by, the color of the display:
  • green: standby / fully charged / weak contact / reverse polarity
    
  • red: charging / activation
  • no light: power supply not connected

Reactivation of discharged cells involves inserting the cell into the charger and checking the voltage. With this function, we can check each cell of 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 OVER 4 SLIM charger, is a separately connected power supply. This prevents unnecessary heating of the charged cell. When the set is working, the power supply itself heats up and not the charged cell. This directly affects the life of the battery. Built-in temperature sensors detect and monitor the temperature of the cells in real time. When the temperature is too high, the charger will automatically adjust the charging current to ensure safe charging.

Note: When the temperature exceeds 50ºC, the charger automatically stops charging, and when the temperature drops, remove and reinsert the battery to continue charging.

With USB outputs, the OVER 4 SLIM charger, can be used to charge smartphones, tablets, etc.
