Are third-party USB-C chargers safe for MacBook Airs?

Yes, they are safe as long as you stick with reputable brands like Anker, Belkin, Spigen, or Amazon Basics and get the wattage right — 30W to 60W works fine for MacBook Airs, and even 100W won’t overload anything. Avoid cheap no-name chargers that risk bad voltage regulation and fire hazards. A solid 45W GaN charger from a known brand costs around $25 and will last years.
