Radiolink CM210 Compact Balance Charger w/ USB-C & Adaptive Charging
Description
- CM210 Balance Charger
- Ultra-compact and lightweight
- Fast charging with USB-C input
- Intelligent adaptive charging
- Real-time battery level LED
- Multiple safety protections
The CM210 Balance Charger is a diminutive yet powerful device designed for efficient energy restoration of batteries. It features a USB Type-C input and supports fast charging with trickle repair to rejuvenate batteries. The charger intelligently adapts the charging current based on the power supply's capability to prevent overload, ensuring a power-friendly operation. It is compatible with a variety of power sources, including adapters, computers, portable power banks, and car chargers, allowing for safe and convenient charging similar to that of a smartphone.
This compact charger is highly portable due to its negligible size and weight, making it an ideal travel companion. It employs a series charging method with a bypass-style balance, utilizing a maximum of 1.5A pulse charging technology. This approach not only achieves rapid charging but also maximizes battery protection by dynamically balancing throughout the entire charging process, significantly reducing the balance time.

The CM210 charger is equipped with a battery capacity indicator LED light, allowing users to monitor the charging progress in real time. It boasts a charging precision of 0.02V and an efficiency greater than 82%. The device also includes a safety algorithm with multiple protections, ensuring safer charging. In the event of a circuit or battery fault, the charger will automatically stop charging and provide an LED alarm indication. Additional safety features include over-temperature protection, which adjusts the charging current if the board temperature exceeds certain thresholds, and power protection which adapts the current to accommodate various charging heads.
Furthermore, the charger has a low-voltage pre-charge and battery repair function, which can restore the capacity of over-discharged batteries, extending their lifespan. During the charging process, the device automatically detects the battery capacity and switches to trickle charging mode when the battery is nearly full, optimizing the charging rate to enhance battery life and performance.
Please note that the actual charging time may vary depending on the power supply's maximum current output. The charger's safety features are designed to protect against potential hazards, and users should always follow the manufacturer's guidelines to ensure proper operation.
