- Will it fast-charge a MacBook Air?
- Yes. The 70W output covers the MacBook Air's fast-charging rate, and it also fast-charges 13- and 14-inch MacBook Pros, though those can draw more than 70W under heavy load.
- Does it charge a 16-inch MacBook Pro at full speed?
- No. The 16-inch MacBook Pro accepts up to 140W, so this adapter charges it more slowly, especially while the laptop is in use. Apple's higher-wattage adapters are the match for that machine.
- Is a cable included?
- No. The adapter ships without a cable, so you need a USB-C to USB-C cable for MacBooks and iPads, or a USB-C to Lightning cable for older iPhones.
- Can it charge an iPhone?
- Yes. It supports USB Power Delivery, so a recent iPhone charges at its fastest wired rate when paired with the right cable.
- Does it work with non-Apple laptops and phones?
- Yes, any device that charges over USB-C Power Delivery will draw what it needs, up to 70W. Some devices may charge more slowly than with their own higher-wattage adapter.
- How does it compare with Apple's 96W and 140W adapters?
- It is smaller and lighter but delivers less power, so it suits MacBook Air and smaller MacBook Pro models rather than high-wattage 16-inch configurations.
- Where is the Apple MKFP4AM/A USB-C Power Adapter 70 W cheapest?
- At Best Buy, for $59.00, as of our latest check.
