Can I charge a MacBook from a car charger?

Yes — any USB-C car charger delivering 60W+ will charge a MacBook Air. MacBook Pro 14-inch needs 70W+, and MacBook Pro 16-inch needs 96W+. The Baseus 160W in this guide handles even the largest MacBook Pro.

Will a fast car charger damage my phone battery?

No. Modern phones regulate incoming power regardless of charger wattage. A 67W charger connected to an iPhone delivers only the 27W the iPhone accepts. The phone's charge controller is the gatekeeper, not the charger. Using fast charging regularly may slightly reduce long-term battery lifespan compared to slow charging, but the difference is minimal.

Do I need a USB-C to USB-C cable for fast charging?

Yes. USB-A to USB-C cables are limited to 12-18W regardless of charger capability. For 20W+ fast charging, you need a USB-C to USB-C cable rated for at least the wattage your charger delivers. A cheap cable can bottleneck an expensive charger.
