The XTAR PB2S charger charges up to two Li-ion batteries via two independent channels and also functions as a power bank. Its three-stage TC/CC/CV charging process includes an initial low-current charge for cells below 2.9 V, constant-current charging, and a final charge with decreasing current up to 4.2 V. It supports reactivating deeply discharged cells and 0 V cells, although this may not be possible if they have sustained irreversible damage.
It is powered via USB Type-C with QC 3.0 and PD 3.0. A USB Type-C cable is included, while the power adapter is sold separately. The magnetic cover for the charging compartment, along with thermal, short-circuit, and reverse battery insertion protections, round out its features.
