UC2 2-Bay 3.6V/3.7V Li-ion Battery Charger – Key Features
Independent 2‑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 – Two channels deliver up to 1A for fast charging; charging current: 1A×2 / 0.5A×2.
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 – Supports 3.6V/3.7V Li-ion 10440 / 14500 / 16340 / 18500 / 18650 / 21700 / 26650. Fully compatible with all 3.6V/3.7V lithium-ion batteries you have on hand, including protected 21700 batteries.
Type‑C Input – Powered via Type‑C, works with 5V/2A adapters and QC/PD chargers (5V mode). Compact size: 137.5×76×32mm, only 123g.
