If you’re trying to figure out which USB-C charger to use for your Apple devices, here’s a simple guide to help you. Always use the charger that came with your device, whether it’s your iPhone, iPad, MacBook, or HomePod mini. However, if you want to use a different charger, make sure it provides the right power specifications to keep your device safe and charging efficiently.
Most higher-wattage USB-C chargers can work with your Apple device as long as they deliver the right voltage and enough amperage. Here are some common Apple USB-C power adapters and their voltage and current ratings:
- 18W charger: 5V at 3A or 9V at 2A
- 20W charger: 5V at 3A or 9V at 2.22A
- 29W charger: 5.2V at 2.4A or 14.5V at 2A
- 30W charger: 5V at 3A, 9V at 3A, 15V at 2A, or 20V at 1.5A
For example, the HomePod mini requires a charger that supplies around 9V at 2.22A. It can also tolerate a charger that delivers 9V at 2A, which is close enough for safe charging.
It’s important to avoid using the 29W charger for devices other than specific Mac models. For instance, it isn’t compatible with the HomePod mini. The 30W charger, however, works well for most devices that need more power.

Remember, the field of USB-C chargers is always changing as new models become available. Keep checking for updates or new information to make sure you are using the best charger for your device. If you come across new or better options, they might be worth trying out to keep your devices safe and charged efficiently.
