So before buying one, make sure you know exactly what you're getting. A lot of third-party chargers aren't true MagSafe chargers because, while they can magnetically hold and charge your iPhone, they aren't approved by Apple and so will only charge it at 7.5-watts and not the faster 15-watt charging speeds. You would not use a 45W adapter with that computer it would not. For instance If you have a MacBook (13-inch Late 2009) that normally uses a 60W adapter, you can also use an 85W adapter with that computer. There are few true MagSafe wireless chargers available right now. Although you should always use the proper wattage adapter for your Apple portable, you can use an adapter of a higher wattage without issue. You'll want to buy a wall adapter that's 20-watt (or higher) so that it can properly power your MagSafe wireless charger. Most wireless chargers do not come with a compatible wall adapter - brands do this to keep the cost down (and as an environmental initiative) - so you'll need to buy one separately. Of course, no matter if it's a MagSafe wireless charger or a Qi wireless charger, it's going to be limited by the power adapter you pair it with.
The only catch is that the new "mini" iPhones, which support MagSafe, can only charge at a max of 12 watts over MagSafe (which is still much faster than over standard Qi). MagSafe Wireless Chargers vs Qi Wireless ChargersĪ true MagSafe charger can charge an iPhone 12 or iPhone 13 at 15 watts, which is twice as fast as the 7.5 watts that any iPhone can charge when using a Qi-wireless charger.
On the 14-inch MacBook Pro, these ports can be used for fast charging but fast charging the 16-inch MacBook Pro requires using MagSafe 3 and the 140W adapter because the Thunderbolt 4 predates the USB-C PD 3.1 standard and tops out at 100W. My colleague Sean Hollister, for example, has a Dell dock that outputs 130W, but it won’t work with other laptops because there previously wasn’t an open standard to support it.Īs well as its use of the USB-C PD 3.1 standard, Apple also confirmed that the brick is its first gallium nitride (GaN) charger, which means it’s using the material that allows companies to build higher-powered chargers that are smaller in size than their traditional counterparts.Īs well as the specs of the charging brick, Apple also confirmed that any of the new MacBooks’ Thunderbolt 4 ports can be used to charge the laptops. That hasn’t been the case with some USB-C laptop fast chargers in the past, which have had to go off-spec to offer charging speeds over 100W (the previous cap on the USB-C Power Delivery spec). The 140W charger has a single USB-C port. It also means that MacBook owners have the flexibility of using compatible third-party charging bricks with the new MacBooks. Using the USB-C PD 3.1 standard means Apple’s new charging brick will be cross compatible with other devices that use the same power delivery standard, which was announced earlier this year alongside the USB Type-C Release 2.1 specification. Meanwhile, the new 14-inch MacBook Pros come with 67W and 96W chargers, depending on the exact model. As well as being included with the new 16-inch MacBook Pro, the brick is available separately for $99 (not including the USB-C-to-MagSafe cable, which costs an extra $49). Apple’s new 140W charging brick, which works with a new MagSafe charging cable to power the new 16-inch MacBook Pro, uses the USB-C Power Delivery 3.1 standard, Apple has confirmed to The Verge.
