I was looking for a flexible, compact DC to USB-C power solution and came across the PD65W Fast Charging Module. It is a compact USB-C Power Delivery module that converts a DC input voltage into a USB-C output with power delivery(PD), enabling fast charging for devices such as smart phone, tablets, laptops, or for use in DIY electronic projects Typical use cases include building chargers or power banks - for example, using a battery pack(12V lead-acid, Li-ion pack, or a car battery) to provide a USB-C PD output for charging or powering USB-C devices. It is also suitable for upgrading a DC power supply to USB-C PD output such as converting standard 12V system(car, solar panel, battery) into a modern USB-C PD source for laptops and tablets. I designed the module and the Elecrow team performed the PCBA assembly. Their service helped me a lot because the board included SMD components that would be difficult to solder manualy. I received a great support and the delivery time was fast.
