MEMO CX20 Fast Cooling Magnetic/Clip 2-in-1 Mobile Phone Semiconductor Cooler – Black

Keep your smartphone cooler during intensive gaming, streaming, and extended use with the MEMO CX20 Semiconductor Phone Cooler – Black.

Using TEC semiconductor refrigeration technology, the CX20 actively transfers heat away from the back of your phone rather than relying on airflow alone. Its versatile 2-in-1 mounting system lets you attach it magnetically to compatible phones or use the included back clip with a wider range of iPhone and Android devices.

Compact, lightweight, and powered through USB-C, the CX20 is designed to help reduce heat buildup and maintain more consistent smartphone performance during demanding gaming sessions.

Key Features

TEC Semiconductor Cooling Technology
The CX20 uses a thermoelectric semiconductor cooling plate to actively draw heat away from your smartphone for faster cooling than a conventional fan-only design.

Fast Cooling for Gaming
Designed to help control temperature during demanding mobile games, extended streaming sessions, video recording, and other intensive smartphone use.

2-in-1 Magnetic + Clip Mounting
Choose between:

• Magnetic attachment for compatible magnetic / MagSafe-style phones
• Universal back clip for non-magnetic smartphones

This gives the CX20 broad compatibility across iPhone and Android devices.

Strong Magnetic Attachment
Compatible magnetic smartphones can attach directly to the cooler for a clean, compact setup without a conventional phone clamp.

Universal Back Clip Included
For devices without suitable magnetic attachment, the included clip holds the cooler securely against the back of the phone.

Compact & Lightweight Design
At approximately 65.8g, the CX20 adds relatively little weight to your gaming setup and is designed to avoid interfering with your grip.

USB-C Powered
The cooler operates from an external USB power source through its Type-C port.

Up to 11.5W Cooling Power
Current CX20 Black-variant specifications list a maximum operating power of approximately 11.5W when supplied with suitable power.

Quiet Airflow Design
The internal airflow system is designed to reduce unnecessary fan noise, making the cooler suitable for gaming while using voice chat or a microphone.

Specifications

Semiconductor Cooling

Unlike a basic cooling fan that only circulates air around the phone, the CX20 uses a TEC thermoelectric cooling element.

The cold plate makes direct contact with the rear surface of the smartphone and transfers heat into the heatsink, where the fan then dissipates it into the surrounding air.

This can help reduce:

• Smartphone heat buildup
• Thermal throttling during intensive use
• Performance drops caused by excessive temperature
• Discomfort from holding a hot phone

Actual cooling performance depends on ambient temperature, phone design, workload, case thickness, mounting position, and power supply.

Ideal for Mobile Gaming

The CX20 is particularly useful during demanding games such as:

• PUBG Mobile
• Call of Duty Mobile
• Genshin Impact
• Mobile Legends
• Fortnite Mobile
• Honkai: Star Rail
• Other graphically intensive mobile games

Reducing heat buildup can help the smartphone maintain more consistent performance during longer gaming sessions.

Magnetic Mounting

Compatible magnetic or MagSafe-style smartphones can attach directly to the CX20.

For the best cooling performance, the cooling surface should sit flat against the rear of the phone with strong contact around the processor / main heat-producing area.

Clip-On Mounting

For Android devices and other smartphones without suitable magnetic attachment, use the included universal back clip.

The clip provides a secure alternative without requiring the phone itself to contain a magnetic mounting system.

Power Requirements

The CX20 is a wired cooler and does not contain a rechargeable battery.

For full cooling performance, use a suitable USB power adapter or power bank capable of supplying approximately:

5V ⎓ 2.5A

Using an underpowered USB source may reduce cooling performance.

Compact Gaming Design

With dimensions of approximately 62.5 × 62.5 × 28mm and a weight of around 65.8g, the cooler is designed to remain compact enough for handheld mobile gaming.

Its small footprint helps leave more space available for your fingers and gaming grip.

Compatible Devices

Suitable for a wide range of:

• Compatible iPhones
• MagSafe-equipped iPhones
• Android smartphones
• Samsung Galaxy phones
• Xiaomi / Redmi / POCO phones
• HONOR smartphones
• OPPO and realme devices
• Other compatible mobile phones

Magnetic attachment requires a compatible magnetic surface. Other devices can use the supplied clip.

Perfect For

• Competitive mobile gaming
• Long gaming sessions
• PUBG Mobile players
