It is not good for the laptop and it will strain the power adapter and could cause the adapter to burn out or fail in some way.
It is dangerous to regularly use a lower wattage power adapter with a laptop that draws more power. Notice that I said that this could be done short-term. A lower wattage power adapter can’t provide enough power to both operate the laptop and charge it, but a lower wattage power adapter could be used, in a pinch, to either temporarily power or charge the laptop’s battery. I agree with this, but a bit more explanation can be helpful. Apple’s support article indicates that lower wattage adapters will not provide enough power. It’s not always fine to use a lower wattage power adapter on a laptop that consumes more power than the power adapter can provide. A laptop that consumes less power will simply pull less power, fewer watts, from the power adapter. The power rating (aka wattage) of the adapter indicates the maximum power that it can supply. For example, you could use a 13-inch MacBook Pro’s 60 watt power adapter on a 13-inch MacBook Air, which shipped with a 45 watt power adapter.

Unfortunately, the opposite is not possible. One can buy a MagSafe to MagSafe 2 adapter to let the older adapter fit into a laptop which requires the thinner MagSafe2 connector. In about 2012, Apple switched to a thinner version of this adapter called the MagSafe 2 adapter. I think it is helpful to start by talking about the two connectors you’ll find on Apple’s power adapters made between 2006 and the present (early 2016). In about 2006, Apple introduced the original MagSafe adapter. Lower wattage adapters will not provide enough power.” Let me elaborate on what Apple states in their support article. “You can use a compatible higher wattage adapter without issue, but it won’t make your computer charge faster or operate differently. Apple’s Support article on the subject states the following. Have you ever wondered if you could use the power adapter that came with another model of Mac laptop with your Mac laptop? In most cases, the answer is yes, but there are a few details to be aware of.
