• Smartphones with Built-in Magnets (MagSafe for iPhones): The cooler readily attaches to iPhones that have MagSafe technology (iPhone 12 series and newer) without needing any additional accessories. The magnets in the cooler align with the magnets in the phone for a secure fit.
• Smartphones without Built-in Magnets (Android and Older iPhones): For phones that don't have built-in magnetic capabilities, the CX07 typically comes with or is compatible with magnetic stickers or plates. These thin metallic rings with adhesive backing can be attached to the back of your phone (or a thin case), allowing the magnetic cooler to then attach securely.
• Universal Compatibility via Optional Clip: Some versions or similar magnetic coolers may also include a detachable back clip as an alternative attachment method. This clip can accommodate a wider range of phone sizes, typically from around 4.5 to 7 inches in width, making it compatible with most Android phones and older iPhone models, even with certain cases.

Key Considerations for Compatibility:

• Phone Case: For the best magnetic adhesion, it's generally recommended to use the cooler without a phone case or with a MagSafe-compatible case that has its own magnetic ring. Standard phone cases can weaken the magnetic connection.
• Size: While the magnetic attachment is universal with the use of a sticker, the physical size of the cooler is designed to fit the back of most smartphones comfortably. Very small or unusually shaped phones might have some compatibility issues.
• Magnetic Sticker Placement: When using a magnetic sticker, ensure it's placed in a central location on the back of your phone to ensure proper contact and balance with the cooler.

In summary, the CX07 Cell Phone Cooler is designed to be broadly compatible with most modern smartphones
