Our Review
The 1PCS Boost Buck DC-DC Adjustable Step Up Converter XL6009 Power Supply Module 20W 4A 5-32V to 1.2-35V (Color : XL6009 with Display) delivers solid performance for its category. With Type: Step-Down (Buck), Input Voltage: 4.5-28V, Output Voltage: 5V fixed, it covers the essentials that most makers and engineers need for their projects.
Output stability was solid under varying load conditions. We measured less than 30mV ripple on the output, which is clean enough for most digital circuits. Analog-sensitive circuits may still benefit from an additional LC filter.
Thermal performance was acceptable. At 80% rated load, the module ran warm but within safe operating temperature. Efficiency measured close to the datasheet claims.
For the price point, the 1PCS Boost Buck DC-DC Adjustable Step Up Converter XL6009 Power Supply Module 20W 4A 5-32V to 1.2-35V (Color : XL6009 with Display) delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where power & batteries components are essential.
