UC4 4-Bay 3.6V/3.7V Li-ion Battery Charger – Key Features
Independent 4‑Channel Charging with Full LCD Display – Monitor voltage, current range, and 4‑level battery bars for all slots simultaneously on one clear screen. No toggle needed – know your batteries' status at a glance.
Smart Adaptive Current Distribution – CH1 & CH4 deliver up to 1A fast charging; CH2 & CH3 provide 0.5A. When 3 or more batteries are loaded, all channels automatically drop to 0.5A to balance heat and power, protecting both cells and adapter.
Scientific TC‑CC‑CV 3‑Stage Algorithm – Trickle charge reactivates over‑discharged cells (≥0.1V), then constant current fast‑charges to 4.2V, and finally constant voltage tapers current to ≤100mA for a precise ±1% full charge – maximizing battery lifespan.
Comprehensive Safety Protections – Built‑in reverse polarity, short‑circuit, soft‑start, and dynamic power management. Automatically rejects non‑rechargeable batteries (Ni‑MH/dry cells) – safe and worry‑free.
Wide Compatibility & Type‑C Input – Supports 3.6V/3.7V Li-ion 10440 / 14500 / 16340 / 18500 / 18650 / 21700 / 26650 (Only the CH1 and CH4 slots are compatible with 26650 batteries). Powered via Type‑C, works with 5V/2A adapters and QC/PD chargers (5V mode). Compact size: 137.5×120×32mm, only 193g.
