⚠️ Important notes:
-
The module does not support direct battery charging – it is intended solely as a power supply (for charging phones, tablets, laptops, etc.).
-
Do not connect to AC mains! Use it only with a DC power adapter.
-
For 140 W output, use at least a 24 V / 10 A adapter.
-
When powered from 12 V (e.g., in a car), PD output is limited to approximately 36 W.
-
Not all devices automatically accept fast chargingbecause of proprietary manufacturer protocols.
💡 Recommendation for stable performance:
For long-term reliable operation, we recommend using no more than 80% of the power supply's maximum rating – for example, for 100 W output use a 24 V / 5 A power adapter.
📦 Applications:
-
Universal fast charging of mobile devices
-
Solar-powered fast charging of smartphones
-
Powering laptops and tablets
-
Development and test power stations
-
DIY laboratory power solutions
✅ We tested the module with several smartphones including Honor 50, Honor 90 a Samsung Galaxy S21 – fast charging worked without issues on all devices.
