can I buy it and use it on my 15 inch one? Yes. The 60 watt charger may take longer to charge your computer, and in times of high power usage, may not charge the battery.

What are the consequences of using a low-wattage USB-C?

The MacBook Pro 2016s have not been out for very long, and our shop hasn’t yet seen the damage that can be caused by under-powering a USB-C charging port.

How many Watts Does a MacBook Pro have?

The MacBook models only have USB levels of power and data available. “USB-C alone allows 4.5 Watts”. This seems to imply that power delivery above 4.5 Watts is part of the Thunderbolt 3 spec and is not part of any USB specs. I think this is incorrect, as USB-PD defines power delivery schemes for up to 100 W.
