Xtar X4 Charger

Description

The Xtar X4 Charger is a compact 4-channel smart charger for all popular types of lithium-ion (ICR, IMR, INR) and NiMH batteries, featuring several new functions. Dual power supply options: from the mains (110-240 VAC, 50/60 Hz) or via a USB micro connector (5 V/2.1 A). Standard USB output (5V/1A) to power an additional device, e.g., to charge a cell phone, and automatic determination of the charging current based on the type of batteries inserted. The Xtar X4 has a special function for activating protected Li-Ion batteries that read 0V, allowing you to revive a battery you would otherwise have written off. The device features a backlit combined analog-digital display that shows the charging current and displays the current charge level and the time remaining until the battery is fully charged, both graphically and as symbols. If desired, the screen backlight can be turned off. The Xtar X4 charges Li-ion batteries using the optimal algorithm for this type of battery, CC/CV (Constant Current/Constant Voltage) with a soft start, while NiMH/NiCd batteries are charged with constant current in pulse mode, with voltage and current monitoring. The charging current depends on the selected power source and the number of batteries being charged simultaneously.
