Description
2x USB 2A 5V Power Bank Charging Module with 18650 Protection + LEDs
The 2x USB 2A 5V Power Bank Module with protection is a reliable and efficient power source for mobile devices. The circuit allows you to connect 18650 cells with the option to connect them in parallel, which significantly increases the flexibility and total capacity of the battery pack you’re building.
The board is equipped with two USB output ports, each with a maximum current of 2A, ensuring fast and efficient charging. When two devices are connected simultaneously, the maximum current output is 3A.
Four built-in LEDs precisely indicate the current charge level of the cell. An additional advantage is the practical flashlight function provided by a dedicated LED, which is activated by holding down the button for about 3 seconds.
The module was designed with safety in mind—it features built-in protection against over-discharge of the cell. Its compact dimensions make it ideal for portable projects and everyday use.
