60W Mag Safe Power Adapter
does this adapter fits a Mcbook Air early 2015?

Find the right power adapter and cable for your Mac notebook - Apple Support
The 2015 MacBook Air has MagSafe 2. If the adapter has the original MagSafe plug, you'd need the MagSafe to MagSafe 2 Converter.
No problem to use a 60 W adapter with the MacBook Air (even though it came with a 45 W charger), as long as the MagSafe plug fits.
