A Apple support page Designed to charge the iPhone and Apple Watch simultaneously, the company has confirmed that its new Maxoff Dio wireless charger is not compatible with its old 29W USB-C power adapter. If you are using an Apple Power adapter, it is a good idea to use one of the company’s new 30W models Changed the 29W model in 2018 And retail $ 49. This is an unfortunate revelation for anyone with older chargers as the Maxoff Duo box does not come with a charging brick.
Apple’s page does not say what will happen if you insert the MagSafe Duo into one of the old 29W bricks. Macroemers Reports If you do, you can only charge one device, the iPhone or the Apple Watch, more than two at a time. Although the 29W brick appears to meet the wattage requirements of the Maxoff Dio, it does not support the exact combination of volts and amps required.
At this point, it’s a little complicated how quickly each of Apple’s MaxSafe parts will charge your devices. The Standard MagSafe charger It charges iPhones up to 15W, and Apple recommends $ 19 to connect it to the Apple 20W USB-C Power Adapter. The MagSafe Duo ChargerMeanwhile, when paired with a brick of 27W or more it offers a slightly lower 14W charge, as long as that brick supports 9V / 3A. By attaching a 20W power brick that supports 9V / 2.22A you get an 11W charge, and Apple claims that the Duo “needs at least 15W (5V / 3A or 9V / 1.67A) to charge both devices at the same time. If you are charging an iPhone 12 Mini, the maximum charge is 12W attached to the Duo. Oh, and the maximum charge is 7.5W if you charge your phone with a lightning accessory (like a pair of headphones) plugged in.
Numerous devices have very specific requirements for the hardware you need to use to get faster charging speeds, so it’s hard to overstate Apple here. But I think we can all agree that it would have made things so much easier for customers if it had included a power brick in the box with its $ 129 wireless charger.
