What is the minimum and maximum input voltage this module can accept?

The module accepts a DC input voltage range of 12V to 28V. The input voltage must always be higher than your desired output voltage — for example, if you want a 20V output for laptop charging, your input source must supply at least 21V or more.

Can this charger module charge a laptop directly from a 12V car battery or solar panel?

Yes, but with an important note: a 12V source can only support output voltages below 12V (e.g., 5V or 9V for phones). To charge a laptop at 20V via PD, you need a 24V battery or a 24V solar panel setup as the input source.

Which fast-charging protocols are supported, and will it work with my iPhone or Samsung phone?

The module supports PD 2.0, PD 3.0, PPS, QC 4.0, QC 3.0, OPPO VOOC, and OnePlus DASH protocols. iPhones (Lightning/USB-C) and Samsung Galaxy devices both support USB PD, so they will fast-charge correctly; the module auto-negotiates the right voltage for each connected device.

How do I set or adjust the output voltage on this module?

The output voltage is automatically negotiated by the connected device's fast-charging protocol — you do not need to manually set it for standard PD/QC devices. The built-in digital display shows the real-time output voltage and current so you can monitor charging at all times.

What are the physical dimensions of this module, and does it require a heatsink or cooling fan?

The module is compact and designed for DIY integration into enclosures or power station builds. It uses an efficient buck-converter topology that minimises heat generation; however, for continuous 100W operation in enclosed spaces, attaching an optional heatsink or providing airflow is recommended for long-term reliability.
