The Fenix ARE-D2 Smart Charger is a dual-channel charger that can accommodate a wide variety of battery types and charge two at the same time. The high charging current of 2A allows for rapid recharging. It only takes 1.3 hours to fully charge a Fenix 2600mAh battery. The standard micro-USB charging port provides you with options for power supply, as it can be equipped with a USB adapter, a power supply, or a solar panel. With three different charging currents, you can choose the option that best suits your battery. The high-resolution LCD screen allows you to clearly and distinctly monitor the charging status for each slot. When charging a Li-ion battery in channel B, you can also use the discharge function to simultaneously charge other devices. Never let your essential devices run out of power again.
