Apple’s old 29W chargers aren’t good enough for MagSafe Duo

An Apple support page has confirmed that the corporate’s new MagSafe Duo wi-fi charger, which is designed to cost an iPhone and Apple Watch concurrently, isn’t appropriate with its older 29W USB-C energy adapter. In the event you’re utilizing an Apple energy adapter it’s finest to make use of one of many firm’s newer 30W fashions, which replaced the 29W model in 2018 and retail for $49. It’s an unlucky revelation for anybody with the previous chargers for the reason that MagSafe Duo doesn’t include a charging brick within the field.

Apple’s web page doesn’t say precisely what occurs when you plug the MagSafe Duo into one of many older 29W bricks. MacRumors reports that when you do it should solely be capable to cost a single gadget, an iPhone or an Apple Watch, moderately than each directly. Though the 29W brick seems to fulfill the wattage necessities of the MagSafe Duo, it apparently doesn’t help the precise mixture of volts and amps required.

At this level, figuring out how briskly every of Apple’s MagSafe equipment will cost your units is just a little bit difficult. The standard MagSafe charger prices iPhones at as much as 15W, and Apple recommends pairing it with a $19 Apple 20W USB-C energy adapter. The MagSafe Duo charger, in the meantime, affords as much as a barely decrease 14W of charging when paired with a 27W or larger brick, as long as that brick helps 9V/3A. You get 11W of charging by pairing it with a 20W energy brick that helps 9V/2.22A, and Apple says you want “at the very least 15W (5V/3A or 9V/1.67A)” for the Duo to cost two units concurrently. In the event you’re charging an iPhone 12 mini, the utmost cost is capped at 12W with the Duo. Oh, and the utmost cost can be capped at 7.5W when you’re charging your telephone with a Lightning accent (like a pair of headphones) plugged in.

Loads of units have very particular necessities for the {hardware} it’s essential to use to get the quickest charging speeds, so it’s arduous responsible Apple an excessive amount of right here. However I believe we will all agree that it may have made issues a lot less complicated for patrons if it included an influence brick within the field with its $129 wi-fi charger.
