Periodically we hear news, rumors, or just requests to extend reverse charging to Apple devices. The idea is that we can supports our AirPods on the back of our iPhone, for example, and these fill up your battery. The truth is, reverse charging is already here, in Apple’s official MagSafe battery.
Between its presence in this accessory and the recent patent that Apple filed – among many others – it is clear that the company’s interest in charging systems is considerable. Certain pricing systems which, although perhaps inconspicuously, are evolving both in speed and efficiency and which this 2023 could hold a surprise for us
One of the two, either Apple is getting ready to improve MagSafe or it will be the year of reverse charging
We’re talking about all of this in the wake of a patent that, as they tell us in Patently Apple, explores an alignment system for reverse charging that could reach future iPhones as well as other MagSafe accessories. A system that focuses on the magnetic alignment of devices and is crucial for charging efficiency.
One of the keys to the success of MagSafe is the magnetic system – hence its name – which allows us to quickly align the two devices we want to charge. Efficiency, however, goes beyond simple alignment, as it must also take into account the rotation in the horizontal plane
Because? Because if you can afford to lose a little efficiency when recharging your iPhone with the MagSafe charger plugged into the wall, the situation changes when considering the reverse charge. The idea is that all the energy that leaves the iPhone should reach the AirPods, for example, with virtually nothing lost along the way. Or, at least, without losing it due to misalignment.
Thus, Apple patented a double alignment system which, in addition to centering the devices, allows guide its rotation thanks to a system of magnets which adapts according to the circumstances. A system that receives the device to be loaded from any position in a first step, but then accompanies the optimal orientation in a second step.
A system that can benefit both MagSafe itself and make wireless charging possible through greater efficiency. As we said before, we have already seen how the iPhone can charge the MagSafe battery, but it only does so when it has external power. This extra efficiency, through better alignment, can make let’s charge other devices without more than the battery of our iPhone. We will see what this technology is.
