Instant Heat Dissipation with TEC Semiconductor Cooling
The CX21 isn't simply a conventional fan blowing air toward your phone.
It uses TEC semiconductor refrigeration technology based on the Peltier effect. The cooling plate draws heat from the phone's rear surface, while the heatsink and fan dissipate that heat into the surrounding air.
This active cooling approach makes the CX21 particularly useful during:
- Long mobile gaming sessions
- Competitive gaming
- Live streaming
- Video recording
- Video editing on smartphones
- Heavy applications
- Gaming while charging
- Extended social media use
Fast Cooling for Demanding Gaming Sessions
The CX21 is designed to start cooling as soon as it is powered -7°C to -2°C under a 26°C ambient environment, depending on operating conditions.
Actual phone temperature reduction can vary according to the smartphone, case, ambient temperature, contact quality, power adapter, and workload.
Low-Vibration Cooling for Streaming
A loud cooler can become distracting when you're recording voice or streaming.
The CX21 uses a dynamically balanced fan designed to reduce vibration during rotation, helping provide a smoother and less distracting cooling experience.
This makes the CX21 a practical companion for creators who want active phone cooling without adding unnecessary vibration to their setup.
Strong Magnetic Attachment
The CX21 features a built-in circular magnetic system designed to create a firm connection with compatible magnetic devices.
For phones that don't support direct magnetic attachment, the included back clips provide another mounting method.
Two Ways to Attach
Magnetic Mounting
Quick attachment for compatible magnetic phones and magnetic accessories.
Back Clip Mounting
Use the included clips for a wider range of smartphones.
62–105mm wide when using the appropriate mounting method.

Why a Semiconductor Phone Cooler?
A conventional phone fan mainly moves air around the device.
A semiconductor cooler actively creates a cold side and a hot side using thermoelectric cooling. The cold side contacts the phone while the heatsink and fan move the extracted heat away from the cooling assembly.
This makes the CX21 particularly useful when your smartphone is under sustained thermal load from gaming, streaming, recording, or other intensive tasks
