I have a Mac book Pro and my wife just got a Mac Book Air for Christmas. Rather than carry multiple chargers on vacation, is it ok to charge a mac book air with the more powerful 60 watt mac book pro mag safe charger? I have read differing views on this and believe that as long as you are using a charger with an equal or more powerful capacity you are fine. Thanks, Dennis
MacBook Air (13-inch, Early 2015), iOS 10.2
The Mac will only draw as much power as it needs from any charger that exceeds the wattage of the charger that came with it. There will be no additional heat nor will it have any adverse affect on the Mac being charged. What you have posted is fundamentally incorrect. As long as the connection is compatible, everything will be fine.
Ciao.

If your macbook pro is 60 watts and your air is a lower wattage, you can charge it but the air will overheat and possible destroy your battery. You should never use a more powerful adapter on a lower wattage laptop. If you use your air's adapter and it is lower than the pro, then it should be fine. The only problem with using the air is that it might not charge as fast and or it might not charge at all.
It is recommended to use the adapter that was supplied for your specific device, if not, you run the possibility of overheating, not being able to charge or damaging the battery.
To save space, you could just bring the brick and only one of the extension cables so thats one less cable.

You are correct, it is quite fine to use the higher power charger for both computers.
Thanks and Happy New Year!
You're welcome, and all the best in the New Year.

No, it will not destroy the battery.
by destroying, i mean wear out the battery more.
No it will not damage the battery. You even provided a link to the page explaining what happens when you use a higher wattage charger. Find the right power adapter and cord for your Mac notebook - Apple Support
No, it will do absolutely no harm to the battery. The system will use ONLY the current it requires to charge the battery, and no more. The charging block could supply a 1000 Amps, the battery will still only use the current it requires, no more. This is why Apple recommends the 12 watt charging block to charge all iOS devices, not just the iPads.

Uh, no.
This is is not how charging circuits wok.
Chargers don't push current.
A device will draw the current it needs up to the rating of the charger.
If what you state is true, please explain how you can plug your 60 watt power plug into your 1,800 watt wall receptacle?
And what happens when the battery is getting full and no longer requires the full current to charge?
Thanks Andrew. Actually the link you supplied clearly says it's okay to use higher wattage adapter. Very helpful.
Thanks Ciao.
Thanks to everyone who responded.
Happy New Year to all,
Dennis
