It delivers a total max output of 4000 mA with each slot capable of up to 3000 mA, enabling four batteries to be charged simultaneously with independent control. Real-world use shows how a single session can refresh multiple cells quickly, helping you stay prepared for daily tasks, outdoor adventures, or hobby projects. The design prioritizes practical performance, adapting to your battery mix without sacrificing convenience.\u003c\/p\u003e\n\u003ch2\u003eSmart, adaptive charging\u003c\/h2\u003e\n\u003cp\u003eThe LCD display provides real-time insights into battery health, internal resistance, charging current, voltage, charged volume, and estimated charging time. The charger automatically detects battery power level and selects the appropriate voltage and charging mode, then switches between CC, CV, and -dV\/dt as needed. You can also manually adjust charging parameters to suit specific needs or preferences.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic power level detection and voltage\/mode selection for seamless use\u003c\/li\u003e\n  \u003cli\u003eThree charging modes: CC, CV, and -dV\/dt with optional manual tweaking\u003c\/li\u003e\n  \u003cli\u003eIndependent slot control so four batteries can be managed in parallel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerformance and safety\u003c\/h2\u003e\n\u003cp\u003eUMS4 includes an optimized IMR charging program that monitors the process and keeps the cut-off within safe limits to help extend battery life. It supports 3.6V\/3.7V Li-ion, 3.8V Li-ion, 1.2V Ni-MH\/Ni-Cd, and 3.2V LiFePO4 chemistry. A suite of safeguards—automatic internal resistance checks, anti-short-circuit protection, reverse polarity protection, and over-discharge restoration—helps maintain reliability. A fire-retardant PC shell and a built-in temperature regulation system help prevent overheating during longer sessions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic resistance detection, short-circuit protection, and reverse polarity safeguards\u003c\/li\u003e\n  \u003cli\u003eOvertime charging protection and over-discharged IMR restoration\u003c\/li\u003e\n  \u003cli\u003eDurable fire-retardant construction with temperature regulation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePower on the go\u003c\/h2\u003e\n\u003cp\u003eThe USB-C input expands your charging options, compatible with mobile power banks, solar panels, and traditional USB adaptors. This flexibility makes UMS4 suitable for home, workshop, or travel use, keeping your batteries ready when you need them most.
