18650 Dual USB Power Bank Charger Board with Protection

The power bank charger module features a compact size of 6.5 * 2.5 * 0.1cm and a lightweight design of 10.8g. It boasts an impressive internal resistance of the PCM (Protection Circuit Module) of ≤65 mΩ, ensuring efficient power transfer.

One of the key capabilities of this module is the support for both iPhone and Android devices through the inclusion of three USB charging cables. Users can conveniently charge their devices using this versatile power solution.

The module's button function allows for easy monitoring of the power status. By pressing and holding the button after the device is in standby mode, the LED digital screen will display the remaining power, providing users with a clear indication of the available charge.

To ensure the safety and longevity of the charger, the module is equipped with several protection mechanisms. The Overcharge Protection feature detects the voltage at 4.20±0.05V and releases the charge at 4.100±0.05V, preventing overcharging and potential damage to the battery. Similarly, the Overdischarge Protection monitors the voltage, cutting off the discharge at 3.0±0.10V and releasing it at 3.10±0.10V, safeguarding the battery from excessive depletion.

Additionally, the module incorporates a Short Circuit Protection system, which quickly detects and responds to short-circuit conditions, cutting off the load to prevent further damage.

The module's Constant Current feature maintains a steady 2.4A output, ensuring efficient and reliable charging, even under varying load conditions. The Dual Output Current capability delivers a maximum of 5V 2.4A, catering to the power needs of a wide range of devices.

To optimize the performance and longevity of the power bank charger module, it is recommended to operate within the suggested working conditions. The maximum continuous charge and discharge current should not exceed 1.5A and 2.4A, respectively, and the working temperature should be maintained between -5°C and 45°C.

In summary, this power bank charger module offers a compact, lightweight, and feature-rich solution for charging a variety of electronic devices. With its overcharge, overdischarge, and short-circuit protection, as well as its constant current and dual output current capabilities, it provides a reliable and safe charging experience for users.
