Powered via USB-C at 5V 2A, the L4 delivers 0.5A of independent charging current to each of its four slots simultaneously, automatically detecting battery type and selecting the optimal charging algorithm upon insertion. For 1.5V li-ion batteries, the L4 employs the TC-CC-CV charging method; for 1.2V NiMH batteries, it uses XTAR's proprietary control technology — both delivering faster charge times, precise termination, and reduced heat generation compared to conventional charging approaches. The L4 can also revive over-discharged batteries, and its hollow-out design aids heat dissipation and makes battery removal straightforward. Six integrated safety protections provide comprehensive coverage across all charge conditions. The package includes the L4 charger, a USB-A to USB-C cable, and a user manual.\u003c\/p\u003e \u003ch4\u003eApplications \/ Uses\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eCharging XTAR 1.5V li-ion
