MEMO CX21 High-Power Magnetic 2-in-1 Phone Cooler

Key Features

• Aggressive 18W TEC Active Freezing: Driven by a premium 18W Peltier semiconductor chip paired with an expansive 900mm² cooling core surface. It physically extracts intense internal chipset heat rather than just blowing warm room air around the chassis.

• Upgraded Vertical Dual-Airflow System: Combines a 7-blade heat dissipation layout with specialized upward and downward vertical ventilation channels. It rapidly moves heat out of the internal 1280 heatsink matrix while ensuring zero hot air is blown onto your hands during competitive claw-grip holds.

• Flexible 2-in-1 Dual Mounting System: Features a strong built-in full-circle magnetic base for tool-free alignment on MagSafe iPhones or magnetic Android rings. It also includes a detachable mechanical back-clip bracket, offering universal compatibility for any smartphone between 5.5 to 7 inches wide.

• 6000 RPM Turbo High-Speed Fan: Equipped with a dynamically balanced high-speed turbofan that pushes massive airflow while maintaining ultra-quiet, low-noise acoustic operation—keeping your live stream and team audio clear of background buzzes.

• Real-Time Digital Temperature Monitoring: Features a highly clear integrated digital display screen that updates you constantly on your device’s real-time back panel surface temperature.

• Dynamic Custom Gaming RGB Accent: A sleek, circular ring light design outlines the intake fan structure, casting smooth, colorful illumination over your hands to elevate your mobile streaming camera aesthetic.

Technical Specifications

Why Choose the MEMO CX21 over standard coolers?

When ambient room conditions run warm or graphic loads max out your GPU, typical 10W or 15W clip-on coolers struggle to combat rapid frame drops. The MEMO CX21 steps up the power matrix to an aggressive 18W ceiling, enabling a deeper temperature drop inside a highly streamlined 82-gram chassis that won’t strain your wrists during long ranked match grinds. By maintaining a strictly chilled temperature profile, it actively prevents the screen from automatically dimming, controls finger sweat, and stops long-term battery degradation dead in its tracks.

Operations & Usage Advice: The MEMO CX21 does not contain an internal battery and runs entirely via external power. To achieve full 18W high-power operation, connect the included Type-C cord to a fast-charging wall block or an external 9V/2A compatible power bank. Always disconnect the power supply immediately when you stop gaming to prevent excessive water condensation layer drops forming on the cold plate while the phone is powered down.
