Phone Cooler Ice Card

A small magnetic cooler that attaches to the back of your phone to help dissipate heat during heavy use.

What it is

Magnetic phone coolers (sometimes called Ice Card style) use a small fan or thermoelectric element and strong magnets to stick to the back of a phone. They pull heat away from the device during gaming, video recording, or fast charging.

How people use it

Snap it on before a long gaming session or when recording video outdoors. It can help reduce thermal throttling so the phone maintains performance longer.

Strengths and limitations

• Helps reduce overheating
