21700 Li Ion

Universal charger everActive UC-100C with Power Bank function. New version with USB-C socket. The charger is designed to charge popular cylindrical batteries. Thanks to the use of the latest solutions, it will handle almost every battery available on the market, regardless of its type/chemistry. The charger has 4 charging programs, so we can be sure that our cell will be properly charged. EverActive UC-100C is an advanced multi-charger for one cell/battery. The device uses an advanced microprocessor to control the charging process. The user has two charging currents at their disposal (to choose from) 500 mA and 1000 mA. The extraordinary capabilities are complemented by a USB socket acting as a Power Bank with output parameters of 5V DC/1000 mA (1500 mA max) - any Li-ion lithium battery is enough (we recommend good quality 18650/20700/21700 batteries) to turn the charger into a functional and handy portable Power Bank.

Key Features: Supports protected 20700 and 21700 cells Charges Li-ion batteries with a three-stage processor-controlled TC/CC/CV charging process Charges Ni-MH batteries using the CC method Two independent charging channels Three charging currents - 1x 2A / 2x 1A / 2x 0.5A (for Ni-MH and Li-ion cells up to 65mm long) LCD display indicating charging capacity, cell voltage, and charging current Powered by any charger with a 2A USB port or directly from a 230V mains Small size - easy to carry Reactivates deeply discharged cells Protections: short circuit, thermal, and reverse polarity Xtar is a renowned manufacturer of high-quality chargers for Li-ion batteries, flashlights, and Li-ion batteries. Xtar products are sold in over 120 countries, including the USA, Germany, Japan, and Russia. Xtar chargers use the highest quality materials, from the housing to the efficient electronics. All Xtar chargers are CE certified, required for European markets.The X2 is a professional processor-based charger with a three-stage TC/CC/CV charging process and an LCD display. It charges 1-2 3.6/3.7V Li-ion and Ni-MH cells of any capacity in sizes AAA/R03, AA/R6, SUB-C/SC, R14/C, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 25500, and 26650.The Xtar X2 charger's backlit LCD display provides real-time information about the charger's operating status: battery charge in mAh, battery voltage, and charging current.What is the TC/CC/CV charging method? This three-stage charging process for Li-ion cells ensures that the cell is maintained in good condition by charging with the appropriate current at each stage and terminating the charging process at the appropriate time.The individual stages of the TC/CC/CV process are: TC phase: cells discharged below 2.9V are 'wakened' with a lower current. CC phase: after reaching 2.9V, the cell is charged with a constant current of 1x 2A / 2x 1A / 2x 0.5A (depending on the number of cells inserted and their size). CV phase: when the cell is almost charged, the charger switches to charging with a decreasing current until the cell voltage reaches 4.2V. Once 4.2V is reached, the charging process is complete - the battery is fully charged. Charged batteries left in the charger will naturally self-discharge. Charging will resume when the battery voltage drops below 3.9V.The Xtar X2 charger has a function to reactivate deeply discharged cells and cells with a voltage of 0V. Many chargers on the market are unable to charge such batteries. This is where the Xtar X2 charger comes in handy, as it can often "rescue" such cells. Simply insert the deeply discharged battery into the X2 charger as you would during normal charging - the charger will detect the discharged cell and attempt to reactivate it.Warning! Cells discharged below a certain level are irreversibly damaged, and reactivation may be impossible. Avoid deep discharge of Li-ion batteries - this can significantly reduce their lifespan and capacity, or even lead to complete failure.The Xtar X2 charger comes with a 2-pin power cable (so-called figure eight). A power adapter is not included. Any charger with a USB port, such as a phone charger, a USB port, or a computer with a free USB port, will suffice to power the charger. The recommended charger output is 2.1A (2100mA).
