Power doesn’t get “pushed”. Power (or current if you prefer) get’s used . Howerver, if your brick reports 60w, your macbook will behave as if you used a genuine 60W adapter. Meaning; a 15” macbook pro with completely drained or absent battery, wil not boot. Depening on what you do, it can be that you loose charge of the battery instead of gaining as well. Because since it reports as 60W, the macbook will lower the charge current. If you are demanding a higher current then the charging current, your battery will drain as well.
