Fenix ARE-X1 V2.0 Single Channel Smart Charger

The Fenix ARE-X1 V2.0 is a single-channel smart charger designed for Li-ion 18650 and 26650 cells, the most widely used rechargeable batteries in tactical torches, head lamps and professional lighting equipment. Measuring 104x32x32 mm and weighing 48 g (without battery), it fits easily in a pack or pocket when working away from base or in the field.

Input is via Micro USB at up to 5 V / 1.5 A, meaning a power bank, car charger or any standard USB adapter is all you need to recharge wherever you are. Output is regulated at 4.2 V / 1 A, the correct value for Li-ion chemistry: the cell receives the right current without thermal stress or risk of overcharge. The single channel ensures all available power goes to one cell, reducing charge time compared to a multi-bay charger that splits it.

The integrated LED panel shows charge and discharge status in real time, while the residual charge detection function lets you check the battery level before starting a cycle. The USB discharge function allows the loaded battery to be used as an emergency power bank — a useful feature when operating in remote environments where every energy source matters. The charger is rated for use between −20 °C and +50 °C under full load, with humidity tolerance up to 90% at 40 °C for 72 hours: specifications suited to outdoor use in any season.

Key features

• Micro USB input compatible with any standard USB source, including power banks: no proprietary adapter needed in the field.
• Output at 4.2 V / 1 A dedicated entirely to the single cell, for faster and more controlled charging than split-power multi-channel chargers.
• USB discharge function turns the 18650 or 26650 cell into an emergency power bank for external devices.
• LED indicator with residual charge detection: you know immediately whether the battery is ready before starting a charge cycle.
• Operating range from −20 °C to +50 °C under full load, suitable for winter use and hot environments.
• Compact dimensions (104x32x32 mm) and weight of 48 g: takes up no valuable space in a hunting pack or professional kit.
