Apple has released a firmware update designed for the MagSafe Battery Pack, and it turns out the new firmware enables 7.5W charging while on the go, up from the previous 5W limit. In a support document, Apple says that MagSafe Battery Pack owners can update their firmware to the new 2.7.b.0 release to get the faster 7.5W charging capabilities.
7.5W charging is now possible with MagSafe Battery Pack
Apple has pushed out a new firmware update for its MagSafe Battery Pack that enables faster charging options on the go. Previously, the Battery Pack could be charged at up to 7.5W through an iOS device, but the new 2.7.b.0 release pushes this limit up to 10W when connected to an iPad or Mac.
You can update the MagSafe Battery Pack through an iPad or a Mac as quickly as five minutes. Apple suggests iPad users attach a Lightning cable to the MagSafe Battery Pack and then plug in the USB side to an iPad or Mac to initiate the update process.
A firmware update designed for the MagSafe Battery Pack has enabled 7.5W charging capabilities, up from the previous 5W limit—which means that if you own a MagSafe Battery Pack, you can take advantage of this faster charging right now. Though it’s probably best to wait until your MagSafe Battery Pack is at 75 percent charge before you connect your iPhone”, you can update its firmware using an iPad or Mac instead of an iPhone. Attach a Lightning cable to the MagSafe Battery Pack and plug the USB side into an iPad or Mac, then wait while the update is applied (the whole process can take up to a week).
You can now update the firmware on your MagSafe Battery Pack in order to get faster-charging capabilities. Simply attach a cable to the Lightning port and plug it into an iPad or Mac, and it will automatically download the firmware and update.
This update will improve the performance of your MagSafe 45W Power Adapter.
You can check the firmware version of your MagSafe Battery Pack by connecting it to “iPhone” and then go to Settings> General> About> MagSafe Battery Pack. You need version 2.7.b.0 to charge 7.5W.
Apple’s July 29th software update added a firmware option to all iPhone models that can charge at 7.5W when you are on the go, while still charging at 15W when connected to power. This is the same rate of charge as that of the fastest available Qi charging speeds on the iPhone.
If you have an iPhone 12 or iPhone 13 and bought one of our new MagSafe Battery Packs, then you’ve probably noticed that it doesn’t charge quite as fast as the 15W model.
Currently, those who install the firmware update can charge their compatible iPhone 12 and iPhone 13 at a higher speed of 7.5 W. It’s still not as fast as 15W MagSafe® charging, but it’s equivalent to the fastest Qi charging speeds available on the iPhone.
Stay powered longer than ever before thanks to the MagSafe Battery Pack. With a 7.5W charge rate for compatible iPhones, 5W for other iPhones, and 15W when connected to a power source, you’ll be able to charge all of your devices quickly from almost anywhere.
This update will increase the speed of charging the batteries by a factor of 1.25
