Power Bank Module Dual USB- 18650 Lithium Battery Charger

The 5V 2.4A Power Bank Module with Display is a compact, high-efficiency energy conversion board that transforms a single 3.7V lithium-ion battery into a portable power bank. It features multiple input interfaces—Type-C, Micro USB, and Lightning (Apple) for flexible charging options.

The onboard digital display provides real-time feedback of battery percentage and charging/discharging status, while the integrated protection circuitry ensures safe and reliable operation. A dedicated LED connection allows for flashlight functionality, making it a complete power solution for portable and DIY applications
