Qi2
Qi2 is the newer standard for wireless charging. Magnets hold the device exactly on the charging coil, so it charges more reliably and accessories attach by themselves.
What does Qi2 mean?
The standard takes the principle that Apple introduced with MagSafe and makes it available to all manufacturers. A ring of magnets in the device and in the charger makes sure the two always line up correctly.
Besides chargers, accessories benefit too: battery packs, card holders, or car mounts attach magnetically to the back. Not every device that advertises Qi2 has the magnets built in itself. Some need a matching case for that.
A general explanation of the term, not from a video. How it plays out on a specific device in everyday use is covered in the reviews below.
