Input: I would highly recommend! This works just as well as the authentic apple charger for my MacBook Air. Update: After a few days, the charger stopped working. I used my extender adapter and it caused some type of spark when plugged in with this charger and now the charger is no longer functioning.

Was great for a few days and then stopped working.
