The main advantage is the fast charging 3.0 of the battery itself and the wireless charging of the gadget, which is twice as fast as regular charging. It can also be attached to the back cover of the phone. The back covers of the 12/13/14/15 models magnetically attach to the battery without any additional accessories, while for the 8/9/10/X/11 models with wireless charging, it is recommended to purchase a sticker adapter to fully utilize this advantage. However, the anti-slip cover allows for wireless charging without an adapter. The flip stand allows you to free your hands and continue using the phone conveniently while charging.
