Why people pick it

  • Rated 40W continuous with dynamic bursts up to 60W, per Apple
  • AVS support, which Apple names as a requirement for iPhone 18 Pro fast charging
  • Apple quotes 50% in about 20 minutes for iPhone 17 models
  • Small single-port body with folding US prongs

Know before you buy

  • Single USB-C port, so one device at a time
  • 40W sustained is slow for MacBook Pro models
  • Fast-charge figures need a 60W-capable USB-C cable, which is not included
  • Apple does not publish dimensions or weight
