Third-party USB-C chargers are safe — pick the right wattage.

Yes, they are safe as long as you stick with reputable brands and get the wattage right.

MacBook Airs are pretty flexible. The official charger is usually 30W or 35W for the M1 and M2 models, but any good USB-C charger from 30W to 60W works just fine. The laptop and charger negotiate the power automatically, so a 45W or 60W charger will just charge faster when the battery is low. A 100W charger also works — it won’t overload anything.

What you shouldn’t do is grab a random 15W phone charger and expect it to keep up. It will charge, but painfully slowly, and you might drain the battery faster than it charges if you’re using the laptop at the same time.

Stick with known brands: Anker, Belkin, Spigen, or even Amazon Basics. Avoid the $8 no-name chargers from random shops — those are where you get bad voltage regulation and fire risks. A solid 45W GaN charger from a reputable brand costs around $25 and will last years.

Don’t overthink it. Your MacBook won’t explode, and your wallet will thank you.
