Universal fast charger XTAR X4 with four independent channels, an LCD display, and microUSB/230 V power offers safe and efficient charging for Li-ion and Ni-MH batteries. It supports fast charging with currents up to 2 A, includes a deeply discharged cell reactivation feature, and can serve as a power bank (USB 5 V/1 A).
The XTAR X4 charger is a reliable solution for both home and professional use. Four independent slots can simultaneously charge different cell types, while the integrated LCD display shows voltage, charging current, delivered capacity (mAh), and internal resistance in real time. Thanks to intelligent charging algorithms—Li-ion TC/CC/CV and Ni-MH CC—charging is gentle and safe.
The XTAR X4 supports three charging current modes and handles a wide range of battery sizes. The practical power bank (USB 5 V/1 A) allows topping up small electronics using an inserted 18650 Li-ion cell (min. 2200 mAh). Power input is available via microUSB (5 V/2 A) or directly from the 230 V mains. The 0 V reactivation function helps revive deeply discharged cells.
