In this regard, can I use a MacBook Air charger on a Macbook Pro?
You can't use a MacBook's charge cable with a MacBook Pro. The rule of thumb, since the mid-90's, is that more demanding models come with adapters that provide more power: MacBook Air (45W), MacBook Pro 13″ (60W), MacBook Pro 15″ (85W). It's labeled on the brick part.
Furthermore, is MacBook air the same as MacBook Pro? But at $1,249, the MacBook Air has the same eight CPU cores and eight GPU cores as the $1,299 13-inch MacBook Pro. The 13-inch MacBook Pro has a slightly larger battery (58.2Wh vs. 49.9Wh) and quotes two additional hours of battery life compared to the MacBook Air.
Similarly, do all MacBooks have the same charger?
The way Apple power adapters are designed is that you can use any charger on any laptop that has the same, or lower, power rating. For example, you can safely use an 85W power adapter (for MacBook Pro) on a MacBook Air (which requires only 45W) or MacBook (which requires 65W).
What kind of charger does a MacBook Air use?
The newest MacBooks Air models (13-inch, 2018 and later) use a 30W USB-C Power Adapter. The proper Apple MacBook Air charger for models that don't have Touch ID, as old as mid 2012, is a 45W MagSafe 2 Power Adapter.
