What is the maximum output power and which USB-C PD voltage profiles does this module support?

The module delivers up to 65W maximum output power. It supports USB-PD 3.1 PPS voltage profiles ranging from 3.3V to 20V with automatic negotiation, including fixed PDO profiles at 5V, 9V, 12V, 15V, and 20V, as well as PPS (Programmable Power Supply) profiles for fine-grained voltage control.

Can I use this board with a 12V car battery or a 24V solar panel system?

Yes — the module accepts any DC input between 8V and 30V, making it fully compatible with 12V lead-acid or lithium car batteries, 24V solar panel outputs, and standard DC adapters. Just ensure your input source can supply sufficient current to sustain the desired output wattage (e.g., at least 6A from a 12V source for full 65W output).

Does this module charge Apple iPhones and MacBooks, or is it limited to Android devices?

Yes, this module is compatible with Apple devices that support USB-C PD charging, including MacBook Air/Pro models and iPhone 15 series (USB-C). For older iPhones using Lightning, you would need a separate USB-C to Lightning cable; the module itself negotiates PD correctly. Android phones from Samsung, OnePlus, Xiaomi, and others are also fully supported via QC4.0/3.0, SCP, AFC, and PD protocols.

What are the physical dimensions of the board and how should it be mounted in a DIY enclosure?

The board measures approximately 40×20×10mm — roughly the size of a large postage stamp — making it ideal for compact enclosures. It features solder pads for DC input and a USB-C output port; mounting can be done using M2 standoffs through the corner holes or with double-sided thermal tape. Ensure adequate airflow around the board for optimal thermal performance during sustained high-wattage charging.

What happens if there is a short circuit or the input voltage drops below 8V — will the board or connected device be damaged?

No — the module includes comprehensive built-in protection: over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), short-circuit protection (SCP), and over-temperature protection (OTP). If the input drops below 8V or a short circuit is detected, the board automatically shuts down output to protect both itself and the connected device, resuming operation once conditions normalise.
