that Apple support page Confirmed that the company’s new MagSafe Duo Wireless Charger, designed to simultaneously charge iPhone and Apple Watch, is not compatible with the older 29W USB-C power adapter. If you’re using an Apple power adapter, it’s best to use one of the company’s newer 30W models It replaced the 29W model in 2018 And retails for $ 49. It’s an unfortunate revelation to anyone with outdated chargers since MagSafe Duo doesn’t come with a shipping brick in the box.
The Apple page doesn’t say exactly what happens if you attach MagSafe Duo to one of the older 29W brick bricks. Mac rumors Reports That if you do, you’ll only be able to charge one device, iPhone, or Apple Watch, instead of both at once. Although the 29-watt brick appears to meet the MagSafe Duo’s wattage requirements, it does not appear to support the exact volt and ampere combination required.
At this point, figuring out how quickly each of Apple’s MagSafe accessories will charge your devices is a little complicated. The MagSafe Standard Charger It charges iPhones up to 15 watts, and Apple recommends pairing them with an Apple 20W USB-C Power Adapter for $ 19. The MagSafe Duo Charger, Meanwhile, it delivers up to 14W of slightly less charging when paired with 27W or higher, as long as this brick supports 9V / 3A. You can get 11W of charging by pairing it with a 20W power unit that supports 9V / 2.22A, and Apple says you need “at least 15W (5V / 3A or 9V / 1.67A)” to charge two devices in the same Time. If you are charging an iPhone 12 mini, the maximum charge is 12W using Duo. Oh, and the maximum charge is also at 7.5W if you’re charging your phone with a Lightning accessory (like a pair of headphones) connected.
Lots of devices have very specific requirements for the devices that you need to use to get the fastest charging speeds, so it’s hard to blame Apple too much here. But I think we can all agree that it would have made things simpler for customers if I included a power brick in the box along with a $ 129 wireless charger.
