Apple released two chargers using the MagSafe standard in 2020: the MagSafe Charger, which is a single charging pad for iPhone, and the MagSafe Duo Charger, which is a charging mat with both MagSafe and an Apple Watch charger. [2] Apple has also licensed the MagSafe standard to third parties to develop chargers and cases.
Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
When the phone is set on the pad, a coil in the pad creates a magnetic field [1] which induces a current in another coil, in the phone, charging its battery.

Rezence (pronounced reh-zense) was an interface standard developed by the WiPower (A4WP) for wireless electrical power transfer based on the principles of magnetic resonance. The Rezence system consisted of a single power transmitter unit (PTU) and one or more power receiver units (PRUs).
Qi (/ tʃ iː / CHEE) is an open standard for inductive charging developed by the Wireless Power Consortium.It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). [1]
Sanho has since ceased to sell their connector cable for the HyperMac series of external batteries. [21] Fake MagSafe 2 chargers were offered for sale on sites such as Amazon.

In the past, the power source used on the JR Tokai SCMaglev car was generating with a gas turbine generator. In 2011, they succeeded in powering while driving (CWD:charge while driving) across a large gap by the JR Tokai proprietary 9.8 kHz phase synchronization technology developed based on technology similar to AGV's wireless power scheme.
