This module is designed as a 2-in-1 board — it charges a connected 3.7V lithium battery via Micro USB while the boost converter provides adjustable stepped-up voltage output from 4.3V to 27V simultaneously, making it ideal for portable DIY power applications.\u003c\/p\u003e\n\u003ch4\u003eQ: What output voltages does this DC-DC step up boost module support?\u003c\/h4\u003e\n\u003cp\u003eA: The output voltage is continuously adjustable from 4.3V to 27V using the onboard trimmer potentiometer. Common set points include 5V, 9V, 12V, and 24V, but you can dial in virtually any voltage within that range to suit your project's needs.\u003c\/p\u003e\n\u003ch4\u003eQ: What type of battery is compatible with this charging module?\u003c\/h4\u003e\n\u003cp\u003eA: This module is designed for single-cell 3.7V lithium-ion or LiPo (lithium polymer) batteries, charging them to a safe maximum of 4.2V at up to 1A. Always ensure your battery's capacity and C-rating are matched to the module's specifications for safe operation.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the maximum current output of this boost module?\u003c\/h4\u003e\n\u003cp\u003eA: The module supports a maximum discharging (output) current of 2A. For best performance and longevity, avoid sustained loads at or near the maximum current rating and ensure adequate airflow around the module.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
