Wireless mag safe phone charge

Long-time Apple users will remember the power connectors that Apple used on certain laptops from 2006 through 2019. These connectors snapped onto a special power port on the laptops, and were designed so if you tripped over a power cable, it wouldn’t throw your expensive Mac to the floor, but rather detach safely.

Apple re-introduced this term in 2020 for chargers that work with the iPhone and with certain headphones. While the “Mag” part is still true, there’s not much that is “Safe” about it. But the name sounds impressive, and Apple already owned the trademark. Apple also brought this back in Summer 2022, with the release of the M2 MacBook Air, which is currently the only laptop to offer MagSafe charging.

MagSafe charging is a form of induction charging, which is compatible with Qi charging, a standard used by many tech firms to provide cable-free charging. Both of these use a pad with a transmitting coil, and a receiving coil in devices, to transfer electricity. The magnets in Apple’s MagSafe chargers, and iPhones, allow the charging to be more efficient, since they can align the two coils perfectly.
