Hello, the difference between the two is the film format.
The Instax Mini is 5.4 x 8.6 cm. No bigger than a bank card. The images look small, especially to people who have experienced the Polaroid photos of the past, whose format is close to square. But many people find that the Mini format draws its charm precisely from its small size, as it slips neatly into a wallet, for example, so you can always carry a photo of a loved one.
With dimensions of 8.6 x 10.8 cm, the Wide format is simply twice the size of the Mini format. In fact, it's as wide as the Instax film is long. The result is richer, more detailed images.
On the other hand, the 2 cameras can take the same group photos, so with the Mini you'll simply have smaller printed photos.
To charge the battery without damaging it, use the USB Type-C cable supplied with the device and a standard USB mains adapter (such as the one used on a smartphone), with a power rating of between 0.4 watts minimum and 2.5 watts maximum. The device must be switched off during charging, which takes approximately 2 to 3 hours. Avoid using USB hubs or keyboard ports for charging via a computer.
No colour cartridges are needed. Similar to the old Polaroid, the film is exposed and then develops the image within a few minutes. The photos are not printed, even though the function is called 'print'. Unlike Polaroid, the pictures are taken digitally, stored internally and can be edited to a limited extent before they are exposed on the film.
