Product Description
This advanced Dual USB Power Bank DIY Module is an all-in-one step-up booster and charging circuit upgraded with an integrated high-contrast LCD backlight display screen. Designed for building custom high-performance portable power banks, it is compatible with both 3.7V Lithium-Ion (18650) and Lithium-Polymer (Li-Po) cells connected in parallel. The module cleanly boosts variable battery voltages to a stable 5V DC output through two independent USB ports providing dedicated 1A and 2A current paths. The standout feature is the onboard LCD panel, which provides precise real-time diagnostic reporting by displaying exact battery percentage status and active input/output connection states. Complete with built-in protection against overcharging, over-discharging, and short-circuits, it offers a highly professional and interactive foundation for portable power systems, IoT nodes, and bench testing setups.
