It stopped superfast charging after one week. Charger time went from 1hr to 3.5 hrs. I bought it a week ago and used it 3 times. And that's CtoC charging. Won't even deliver enough power to turn make a light blink on my laptop. Worst I've ever bought
This charger advertises itself as compatible for Macbooks, meanwhile, it's very harmful. I bought this for my MacBook pro and after a few hours of use, one of my usb-c ports gave out. I didn't think much of it and continued using it since it was the only charger I had on me. Eventually, the 2nd port gave out as well. I ended up using compressed air in hopes of reviving the ports, thankfully it worked. Do not buy for this for your mac, it harms your battery and will make your usb-c ports turn off due to its unstable power delivery. Just get an Apple charger.
