5V Dual USB Boost Converter Module 134N3P
5V dual USB boost converter module 134N3P—step-up power module for DIY power banks and battery-powered electronics projects.
Description
The 5V Dual USB Boost Converter Module 134N3P is a high-efficiency step-up (boost) power module designed to convert a single-cell Li-ion/Li-Po battery (3.0–4.2V) into a stable 5V DC output. Equipped with two USB output ports, it allows you to power or charge two devices simultaneously.
This module is widely used in DIY power banks, portable chargers, battery-powered electronics, Arduino/ESP32 projects, and emergency backup power systems. It features high conversion efficiency, stable output, and built-in overcurrent, over-discharge, and short-circuit protection for safe operation.
Compact and easy to integrate, the 134N3P boost converter is an ideal solution for portable power applications requiring reliable 5V USB output.
