Features: 21V To 5V Power Conversion: This board turns a 21V battery source into usable 5V output for small electronics, giving project users a compact way to add off-battery charging where wall power is not practical. Two Port Layout: USB-A and Type-C support a flexible charging setup for phones, fans, lights, and other 5V gear, helping you power more devices from the same conversion board during travel or workshop tasks. Attached Wire Assembly: Integrated wires make the module suitable for hardwire builds and project installs, so you can route power into a workshop setup or portable utility box with a cleaner cable run. Compact Board For Mobile Power: The single-board format supports portable charging, workshop setups, and backup power ideas without adding a large enclosure, making it easier to reuse an existing battery pack for everyday use. Single Board In Each Pack: You receive a converter board assembly with visible wiring and two USB outputs, giving clear expectations for replacement, repair, or new battery conversion work right out of the package.
