The HW-357 Adjustable Step-Up Module is a compact and efficient DC-DC boost converter designed for 18650 lithium battery applications. This module steps up input voltage (3.7V) to stable output levels of 5V or 9V, selectable via an onboard switch. Capable of delivering up to 2A output current, it provides reliable power for small electronics, portable devices, and DIY projects.
Engineered for durability and safety, the HW-357 includes built-in overcurrent, overvoltage, and short-circuit protection. LED indicators provide real-time updates on power and charging status. Its compact size and lightweight construction make it ideal for portable applications and integration into custom electronic projects. With up to 92% efficiency, this module ensures minimal energy loss while powering your devices.
