With this adapter I can use my "old" 2 power supplies with my new macbook pro.
It´s working nice more than 1 month.
Does a great job of powering my new Air with the power feed from the Thunderbolt terminal without an extra power supply.
Works perfectly on my MacBook Pro (13-inch, 2017) and my old 27'' Display! Excellent solution to reduce the number of cables on the table!
Just perfect , as a using a backup power supply from my old mackbook air, to my new macbook pro (
Does exactly what it's supposed to do, nothing more or less. It does get quite hot, but it seems to keep the laptop cooler because the power conversion seems to happen in the device rather than my laptop. I had 2 previously useless magsafe power supplies, they now have a reason to exist again!
