The difference between the basic model and the upgrade model: Both look the same, with magnets, control board, bluetooth, battery. The difference is that the basic model does not have a wireless charging function, and the upgraded model has a wireless charging function. Note; wireless charging is not a power bank, the wireless charging power is 10W, it needs to be connected to a USB charging cable, and the interface is type-c. The battery is a 200Mah polymer battery, and the battery only supplies power to Bluetooth. It can last for two or three months when you go out to play and take pictures normally.
