Detailed Product Description
CH2 Intelligent Multi-Function Charger – One charger for many cells, safe and fast charging
The CH2 charger is a truly universal dual-slot charger. It not only supports standard 3.7V Li-ion, 3.8V IMR, 3.2V LiFePO4 and 1.2V Ni-MH/Ni-Cd batteries, but also features dedicated support for 1.5V constant-voltage lithium batteries (4.2V to 1.5V step-down) , making it one of the few chargers on the market that can safely charge these special cells.

🧠 Smart Operation & Display
Battery Type Selection: Within 9 seconds after inserting batteries and powering on, click the “MODE” button to cycle through Li-ion 3.7V, IMR 3.8V, and LiFePO4 3.2V. Ni-MH/Ni-Cd and 1.5V Li-ion batteries are automatically identified; no manual type switching is required.
Charging Current Adjustment: Before charging starts, long press the “MODE” button to toggle between 500mA and 1000mA (for 1.5V Li-ion batteries, the current is fixed at 500mA and cannot be changed).
Battery type cannot be changed during charging, ensuring safe operation.
🚀 Product Highlights
Dedicated Charging Support for 1.5V Li-ion Batteries
Most chargers on the market cannot properly charge 1.5V constant-voltage lithium batteries. The CH2 features a specially designed 500mA fixed-current charging program for these cells, keeping them safe and extending their life.0V Low-Voltage Activation & Recovery
For over-discharged batteries with extremely low voltage, the charger automatically provides a weak trickle activation current, attempting to wake up “sleeping” cells and help recover usable batteries.Multiple Circuit Protections
Built-in safeguards against overcharge, over-discharge, short circuit, and reverse polarity. The charger can also intelligently detect defective batteries before charging begins and will refuse to charge them.Clear LCD Display at a Glance
Real-time display of charging status, battery type, voltage, and current for each slot. Say goodbye to blind charging and enjoy greater peace of mind.Portable Design with USB Power Supply
Compact and palm-sized. Powered by a standard 5V 2A USB source, it works with phone chargers, power banks, car USB ports, and many other scenarios.
⚠️ Safety Warnings & Usage Notes
Use this charger only indoors at room temperature.
Be sure to use a USB adapter with an output of 5V and at least 2A to avoid insufficient power supply.
Before charging, refer to the battery manufacturer’s recommended charging current and do not exceed the maximum allowed current.
The charger may become warm during operation. Keep it away from children and ensure adequate ventilation.
When not in use, disconnect the power and remove the batteries.
