Short answer: Wattage is the power budget. Match Apple’s guidance for your Mac. Higher is safe. Multi-port GaN shares total watts across ports.

Apple recommends adapters by model. Higher wattage is fine — the Mac draws what it needs. Always confirm your exact model. Sources: Apple: Use a power adapter with your Mac · About MacBook fast charging.
| Mac (per Apple Support) | Apple-recommended adapter class | Our note |
|---|---|---|
| MacBook Air (2022+) | 30W / 35W dual / 67W / 70W (+ MagSafe 3 or USB-C charge cable) | 65W third-party GaN is a solid everyday/travel pick; check shared-port limits |
| 14″ MacBook Pro (2021+) | 67W / 70W / 96W | 65W = travel compromise, not primary for heavy sustained load |
| 16″ MacBook Pro (2021+) | 140W + MagSafe 3 path for full Apple fast-charge kit | Do not make 65W your primary |
| 13″ MacBook Pro (2016+) | 61W | 65–100W USB-C class commonly works for charge |
Identify your exact Mac on Apple’s page before buying — configs differ.
