XTAR X2 Battery Charger – Product Overview
The XTAR X2 Lithium-Ion Battery Charger is an intelligent two-bay charger designed for compatible cylindrical rechargeable batteries.
Featuring two independent charging channels, the XTAR X2 can charge two supported batteries simultaneously, even when the cells have different capacities or charge levels.
The charger supports compatible 3.6V/3.7V lithium-ion batteries, including IMR, INR and ICR types, alongside supported 1.2V Ni-MH and Ni-Cd rechargeable batteries.
Its intelligent charging system automatically selects an appropriate charging current based on the installed battery and operating conditions. Supported charging configurations include 2A × 1, 1A × 2 and 0.5A × 2.
A distinctive real-time LCD display provides charging information, including battery voltage, charging current and charging progress.
Unlike chargers that rely solely on USB power, the XTAR X2 offers dual power input. It can operate using its mains power connection or a suitable 5V Micro-USB supply.
The London Vape Wholesale package includes the XTAR X2 charger and a UK three-pin power lead, providing a convenient mains-powered charging option.
XTAR X2 Key Features
Two Independent Charging Bays
The XTAR X2 features two independently controlled charging slots, allowing compatible rechargeable cells to be charged simultaneously. Each bay manages its battery separately.
Up to 2A Fast Charging
The charger supports up to 2A charging for one suitable battery, or up to 1A per bay when charging two compatible cells. Actual current depends on cell dimensions, battery characteristics and operating conditions.
Real-Time LCD Charging Display
The integrated LCD screen displays useful charging information, including cell voltage, charging current and charging progress, making it easier to monitor the charging process.
Dual AC and Micro-USB Input
The XTAR X2 supports mains power at 100–240V AC and an alternative 5V/2.1A Micro-USB input. This provides flexibility when using the charger in different locations.
Automatic Charging-Current Selection
The charger automatically adjusts its charging current according to the supported cell and charging configuration, without requiring manual current selection.
Wide Rechargeable Battery Compatibility
Compatible battery formats include popular 18650, 20700 and unprotected 21700 lithium-ion cells, alongside rechargeable AA and AAA Ni-MH batteries.
Three-Stage Lithium-Ion Charging
XTAR uses a three-stage charging process incorporating trickle charging, constant current and constant voltage stages to manage supported lithium-ion cells.
Automatic Charge Termination
The intelligent charging system is designed to stop charging when a supported battery reaches its appropriate full-charge condition.
Built-In Safety Protections
The XTAR X2 incorporates protections against reverse polarity, short circuits and abnormal operating temperatures, helping reduce common charging risks.
Low-Voltage Cell Activation
XTAR includes a 0V activation function intended for certain compatible over-discharged cells. Never attempt to recover damaged, swollen, leaking or otherwise unsafe batteries.
XTAR X2 Charging Current Options
The XTAR X2 automatically selects the appropriate charging mode from its supported configurations.
| Charging Mode | Maximum Current | Configuration |
|---|---|---|
| Single-Bay Charging | 2A | 1 Compatible Battery |
| Dual-Bay Charging | 1A Per Bay | 2 Compatible Batteries |
| Lower-Current Charging | 0.5A Per Bay | 2 Compatible Batteries |
Charging current is automatically managed. Battery length, chemistry, charge state and available power can affect the selected current. The 2A mode is not suitable for every battery.
Dual Power Input – Mains and Micro-USB
UK Mains Power
Connect the supplied UK three-pin power lead to a suitable mains outlet. The charger supports a universal AC input of 100–240V at 50/60Hz.
Micro-USB Power
Alternatively, use the charger's Micro-USB input with a suitable 5V USB power supply. The specified DC input is 5V/2.1A.
Use one power input at a time and follow XTAR's operating instructions. The X2 uses Micro-USB, not USB-C.
XTAR X2 Compatible Battery Sizes
The XTAR X2 supports a wide selection of rechargeable cylindrical batteries, subject to their chemistry, dimensions and terminal configuration.
*21700 and 20700 Compatibility: The XTAR X2 supports compatible unprotected cells in these formats. Protected 20700 and 21700 batteries with added protection circuits are not supported because of their additional length.
Additional Formats: XTAR also lists support for selected 14650, 17335, 17500, 17670, 18490, 18700, 22650 and 25500 lithium-ion cells, plus compatible AAAA, A, SC and C rechargeable Ni-MH/Ni-Cd batteries.
