efficiency DCDC converter that steps up voltage from 5V to 12V, enabling 12V loads from common 5V USB sources. Output up to 8W, suitable for a wide range of small electronics projects and prototypes. Compact and lightweight design, ideal for portable, spaceconstrained, or embedded applications. USB input for convenient power connection, making it straightforward for DIY enthusiasts to integrate into projects. Clear compatibility: 5V input to generate a stable 12V output for compatible devices up to 8W. Practical size and form factor support easy enclosure integration and portable use; no special tooling required for setup. Use scenarios: Power a small 12V hobby motor or actuator from a USB power bank for portable robotics projects. Run a 12V LED strip or compact display from a USB charger during demonstrations or field work. Provide a compact 12V supply in a development bench setup to prototype and test 12V modules from a USBdriven source.
