3.7V to 12V Mini DC-DC Boost Converter – Adjustable 5V/8V/9V/12V Output, Lithium Battery Step-Up Power Module

Description

Product Overview

The 3.7V to 12V Mini DC-DC Boost Converter is a compact, high-efficiency step-up power module designed to convert a low 3.7V input from a lithium battery to a range of higher output voltages up to 12V .

This essential power solution allows you to utilize the widespread 18650 or Li-Po battery to power devices that require higher voltage rails, such as Arduino boards, routers, sensors, LED strips, and small portable fans. It serves as a universal voltage booster, making it invaluable for DIY electronics and portable projects .

Key Features

• 4 Selectable Output Voltages: Easily configure the module to output 5V, 8V, 9V, or 12V to match your specific device requirements .

• Efficient Step-Up Conversion: High conversion efficiency (up to 92%) ensures minimal power loss when boosting from a lower voltage battery source .

• High Output Current: Delivers stable current with capabilities up to 1A at 5V from a 3.7V battery, perfect for powering development boards and small peripherals .

• Wide Input Voltage Range: Operates with an input range of 2.5V to 5.5V, making it compatible with single 18650 batteries, Li-Po packs, and even 5V USB power sources .

• Ultra-Compact & Lightweight: Tiny form factor (approx. 30mm x 17mm) and low weight (approx. 5g) allows for seamless integration into space-constrained portable projects .

• Integrated LED Indicator: Onboard LED provides clear visual confirmation of the module’s output status .

• Simple Setup: Features a straightforward 3-pin interface (VIN, GND, VOUT) for easy wiring to batteries and loads .
