MEMO CX20 3-Gear Temperature Control Magnetic Semiconductor Phone Cooler — Dual-Purpose Magnetic & Back Clip Mounting, Dynamic RGB Gaming Atmosphere Light, 3-Speed Cooling Modes & Low-Noise Turbo Fan
Key Features & Innovations
3-Gear Temperature Control System: Toggle between three tailored cooling levels (Silent, Strong, and Turbo) to balance fan speed, thermal output, and acoustic preference.
Advanced TEC Semiconductor Refrigeration: Thermo-electric cooling chip acts like a mini refrigerator, directly pulling heat away from your phone to eliminate thermal throttling during games like PUBG Mobile, BGMI, and Genshin Impact.
Dual-Purpose Mounting (Magnetic + Clip): Features built-in MagSafe-compatible magnets for instant snap-on mounting alongside a universal retractable back clip for broad phone support.
Whisper-Quiet Spiral Duct Operation: High-speed turbo fan runs through an acoustic-optimized spiral air duct (28–32 dB output), preventing background fan noise during in-game voice chat or live streams.
Dynamic RGB Gamer Lighting: Eye-catching RGB lighting effects illuminate the cooling fan area, creating an immersive gaming aesthetic.
Lightweight Compact Ergonomics: Weighs approximately 65.8 grams, maintaining a comfortable hand grip without obstructing your fingers while playing in landscape mode.
