1. Protocol Version Dictates Power Limits: PD 3.1 > PD 3.0 > PD 2.0 > QC 4.0.
2. Device Compatibility Priority:High-power devices (e.g., MacBook Pro) require PD 3.1 support. Low-power devices (phones/tablets) are backward-compatible.
3. Actual power depends on device-handshake protocols; non-standard devices may trigger power reduction.

• To achieve a 140W output from the charger, the device must support the PD 3.1 protocol and match the 28V/5A voltage/current profile. Typical compatible devices include the 16-inch MacBook Pro 2023 and later models.Devices that only support PD 3.0/2.0 protocols cannot activate the 140W output.
• To achieve a 100W or 65W output from the charger, the device must support the PD 3.0 or PD 2.0 protocol.
• When the device's battery is fully charged, the system will automatically switch to trickle charging mode (power may drop to 5-10W).
