Can I Use A 45w Charger Instead Of 60w. The wattage of your power supply is a rating of the maximum power that can be drawn down from it. But not the other way round.
Can I use 65W or 90W instead of 45W charger for Inspiron3567 Actually I have lost my 45W charger for my Inspiron 3567 but my friend has both 65W and 90W Dell Original charger. The 60W MagSafe power adapter should work fine on the MacBook Air as well as the MacBook Pro. As long as it is the same voltage and connector type you can use a higher watt adapter.
You can always use an adapter that has a higher power rating than is.
You can use a compatible higher wattage power adapter without issue but it wont make your computer charge faster or operate differently. Using 130W charger instead of 65W. T440p with 20v 225a 45W charger as original but can I use 65w charger. The 45W MagSafe 2 can not provide enough power and is likely to over heat try to provide power and will provide an erratic voltage to the Macbook pro Retina late 2013.
