Solid charger for the price

Picked this up as a backup for MacBook Air and honestly its been working great. It is enough to fast charge the laptop even while Im using it which is all I really needed. Also tried it on my iPhone and it works well. Easy to connect, no need to setup anything

Durable - Works for my Mac and my kids’ computers

My kids are constantly losing my MacBook charger and they’re expensive! So on Prime Day I treated myself and bought this charger - which I told them they’re never ever allowed to touch under any circumstances. The brick is pretty big compared to what I’m used to. The cord length is fine and it charges my MacBook quickly just like I wanted it to! I was really pleasantly surprised by how legit this charger is for the price, given how costly they can be. It seems really sturdy. Turns out, this charger also fits the Chromebooks that all 3 of my kids use for school, and whose chargers are always missing. So “my” charger is once again a shared charger. But it gets all 3 Chromebooks and my laptop fully charged in a night. Nice, easy, durable product for a great price.
