If like me, you were a little disappointed that you spent almost £1000 on an iPhone 12, only to find that you needed to spend a further £40 to benefit from the MagSafe charging function (as a MagSafe charger was not included) then this could be your answer. This charger performs exactly the same function as the branded product for half the price. It is designed with the Apple ethos (white USB C cable, aluminum disc with clear acrylic and white plastic cover. It works to a depth of 8mm, which means it will work through most cases, allowing you to leave the case on. I found that with my standard liquid silicon case it worked fine for charging, but the magnetic field was weak and could be easily displaced, while out of the case the magnetic attraction was strong enough to not be easily dislodged.
It will output up to 15W from either a 9V or 12V input, which means it can be used by Samsung Galaxy phones and your AirPods or AirPods Pro as well as Samsung earbuds, although obviously the magnetic feature is not being used in these circumstances.
