Dual USB 5V 2.4A Power Bank With LED Display 18650 Charger Board

A Dual USB 5V 2.4A Power Bank with LED Display 18650 Charger Board is a versatile circuit board designed for creating portable power banks. Here are the key features and components typically found on such boards:

1. Dual USB Outputs: These boards usually feature two USB ports capable of delivering 5V output at up to 2.4 amps each. This allows simultaneous charging of two devices like smartphones, tablets, or other USB-powered devices.
2. LED Display: The LED display provides real-time information such as battery capacity, voltage levels, and sometimes even current output. This helps users monitor the charging status and remaining power of the power bank.
3. 18650 Battery Compatibility: This board is designed to work with 18650 lithium-ion batteries, which are common and widely available. Usually, these boards can accommodate multiple 18650 batteries (typically 1 to 4 batteries depending on the design), which are connected in series or parallel to achieve the desired voltage and capacity.
4. Charging and Protection Circuitry: To ensure safe operation, these boards include built-in protection circuits such as overcharge protection, over-discharge protection, short circuit protection, and thermal protection. This helps prevent damage to the batteries and connected devices.
5. Input Charging Port: There is typically a micro-USB or USB-C port for charging the power bank itself. Users can connect a standard USB charger or power source to recharge the batteries.
6. Compact and DIY-friendly: These boards are compact and designed for DIY enthusiasts who want to build their own custom power banks. They often come with pre-soldered components for ease of assembly.
7. Additional Features: Depending on the model, some boards may include additional features like flashlight function, power switch, or indicators for different charging modes.

These charger boards are popular among hobbyists, makers, and electronics enthusiasts who enjoy creating customized portable power solutions. They offer flexibility in battery configuration and output capacity, making them suitable for various applications from camping to emergency power backups.
