Overview
The KATEX S-816 is a high-precision battery activation plate designed for professional technicians and DIY enthusiasts. When a lithium battery sits at 0% for too long, its internal protection circuit often prevents it from charging via the phone’s port. The S-816 bypasses this by providing a direct, regulated “jolt” (activation) to the battery cells, bringing them back to a voltage level where they can be used normally again.
Key Features
Intelligent Auto-Polarity: No need to worry about positive and negative terminals. The board automatically detects the battery orientation to prevent short circuits.
One-Key Activation: Simply connect the battery and press the “Activation” button to wake up a sleeping or “dead” cell.
Fast Charging: Supports up to 2A charging current, allowing you to quickly top up a battery for testing.
Safe Charging Mode: Automatically stops charging when the battery is full to prevent swelling or damage.
Visual Indicators: Features LED lights (Red for charging, Green for full, Blue for activation) for easy status monitoring.
Wide Compatibility: Multiple connector ports support everything from older iPhone models to the latest Android flagships (Samsung, Oppo, Vivo, Xiaomi, etc.).
