Magnetic wireless charging is built around a ring of magnets on the back of the phone paired with a matching magnet in the charging pad. These magnets automatically pull the phone into the correct position on the pad, keeping the coils perfectly aligned every time.
Guaranteed alignment solves the biggest efficiency problem in wireless energy transfer; the losses that classic Qi pads suffer from user misalignment are largely eliminated in magnetic systems. That translates into less heat and more stable charging at the same wattage.
The magnetic system also expands the accessory ecosystem; card holders, stands and car mounts that snap onto the magnet can keep the charging connection stable even as the phone moves from one spot to another. That is a particularly practical advantage for drivers using navigation.
One limitation of the technology is that overly strong magnets could risk affecting some magnetic cards or bank cards, which is why manufacturers cap magnetic field strength according to specific safety standards.
Charjett's magnetic wireless charging products are designed to balance easy alignment with safety standard compliance, aiming to work seamlessly with MagSafe-compatible phones.
