Our Review
The KEAcvise 5-Pack XL6009 Boost Converter Module - DC-DC Step-Up Power Module 3-30V to 5-35V, 400KHz 4A Switching Frequency delivers solid performance for its category. With Type: Step-Up (Boost), Input Voltage: 4.5-28V, Output Voltage: 3.3V 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.
Overall, the KEAcvise 5-Pack XL6009 Boost Converter Module - DC-DC Step-Up Power Module 3-30V to 5-35V, 400KHz 4A Switching Frequency fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
