Smart LCD 4-Slot Independent Battery Charger - Touch Dimming | 0V Activation | 3-Stage Charging
Description
This charger features four fully independent charging slots, each with a high-definition LCD screen that displays real-time voltage, capacity percentage, and battery type (Li-ion/Ni-MH). Supports mixed charging, intelligently distributes current (1000mA/slot for 1-2 batteries; 500mA/slot for 3-4 batteries). Includes touch brightness control, 0V over-discharge activation, trickle charging, auto battery type detection, and comprehensive safety protections. Type-C powered with a 3-stage charging algorithm - faster, safer, and fully transparent.
USB Designed
Type-C input works with any USB port - phone charger, power bank, computer, etc. No wall outlet required. Recommended input: DC 5V/2A or higher (adapter not included).
High-Definition LCD Display
Each slot has an independent LCD screen showing:
Real-time voltage (e.g., 4.22V / 1.50V)
Capacity percentage (e.g., 50%)
Battery type (Li-ion / Ni-MH)
The status of up to four batteries is clearly visible at the same time - no need to swap or guess.
Fast Charging Current
Smart current distribution balances speed and safety:
Charging 1-2 batteries: up to 1000mA per slot
Charging 3-4 batteries: up to 500mA per slot
Typical charging times:
18650 3500mAh ~2 hours
AA 2000mAh ~7 hours
AAA 600mAh ~2 hours
Automatically stops when fully charged - safe for all batteries.
Touch to Control Brightness
Touch buttons adjust screen brightness. Screen automatically dims after 30 seconds of inactivity - saves power and prevents glare at night.
Comprehensive Protection System
Built-in smart protection chip provides:
Overcharge protection
Short circuit protection
Reverse polarity protection
Over-temperature protection
Low voltage protection
Trickle charge mode (pre-charges deeply discharged batteries at low current)
Over-Discharge Battery Activation (0V Activation)
Can activate over-discharged Li-ion batteries that have entered protection mode (with protection circuit). Once inserted, the charger automatically detects and attempts activation, then resumes normal charging - extends battery life and saves replacement costs.
Auto-Identify Battery Types
Automatically distinguishes Li-ion (4.2V cutoff) from Ni-MH/Ni-Cd (1.48V cutoff) and applies the correct charging algorithm (CC-CV for Li-ion, - V termination for Ni-MH). No manual settings required.
3-Stage Smart Charging (TC-CC-CV)
For Li-ion batteries: trickle constant current constant voltage, optimizing speed without damaging cells. For Ni-MH/Ni-Cd: - V detection ensures a precise full cut-off, preventing overcharging.
Battery Compatibility
Widely compatible with most cylindrical rechargeable batteries:
Li-ion (3.7V):10440, 14500, 16340, 17335, 17500, 17650, 18350, 18500, 18650, 18700, 25500, 26650, etc.
Ni-MH/Ni-Cd (1.2V):AA, AAA, C, SC, F6, etc.
