I’ve seen this question quite a lot lately in various forms, so hopefully I’m able to provide some clarity on this topic. From now on I will use this thread to collect all similar questions. I will also make edits to make this post more complete depending on questions.
Charger compatibility
USB-C charging is a versatile and efficient way to power various devices. It utilizes Power Delivery (PD) and Programmable Power Supply (PPS) protocols to dynamically negotiate power delivery, ensuring optimal charging efficiency and safety. While it’s generally safe to use any USB-C charger with a compatible device, understanding the charger’s capabilities and the device’s power requirements can optimize charging speed.
Misconceptions and Their Impact:
- Using a Low-Power Charger with a High-Demand Device: The device will only receive the power it needs, potentially extending charging time.
- Using a High-Power Charger with a Low-Demand Device: The charger will automatically adjust its output, but the device won’t benefit from faster charging speeds.
- Using a Non-PD Charger with a PD-Compatible Device: The device will still charge but may not achieve the fastest charging speeds.
