What is the MEMO CX20 Magnetic Phone Cooler?

This is a portable phone cooler from the Adatun catalog built to tackle heat issues common in modern smartphones. Many users notice their devices warming up quickly during extended gaming sessions or when running demanding apps. The CX20 addresses this with a dual cooling system that pairs a precise 23 × 23 mm TEC semiconductor cooling chip with active air circulation from its 7-blade fan.

We designed it for real-world use where silence matters as much as performance. The fan can spin up to 6000 RPM yet stays quiet in Silent mode, making it suitable for office or travel. Power comes through a standard USB Type-C connection at 5V / 2.5A for 11.5W consumption, ensuring it runs efficiently without draining your phone battery excessively. At just 65.8g and measuring 62.5 × 62.5 × 28 mm, it slips easily into a pocket or bag.

How the Dual Cooling Technology Works

The core of the MEMO CX20 is its high-efficiency TEC semiconductor cooling chip sized at 23 × 23 mm. This component creates a cold side that contacts the phone while moving heat away. Paired with the 7-blade silent fan, it pushes cool air across the surface for faster dissipation than passive methods alone. Aluminum alloy in the build aids conduction so heat leaves the device quickly.

Three cooling modes give control: Silent keeps noise low for calls or light tasks, Strong offers balanced performance, and Turbo delivers maximum cooling when temperatures climb during heavy gaming. The system stabilizes device performance by lowering temperatures, which can reduce thermal throttling in processors.

Real Use Case: Gaming Sessions

Gamers often face frame drops and discomfort from warm phones. The CX20 attaches securely via its magnetic or back clip system (clip range up to 95 mm) and activates Turbo mode to maintain lower temperatures. This helps keep gameplay smooth over hours without the phone becoming too hot to hold comfortably. The lightweight 65.8g design means it does not make the phone feel unbalanced during portrait or landscape use.

Installation and Setup

Attaching the MEMO CX20 takes seconds. For magnetic phones, align the cooler so its built-in magnets snap securely to the back. For other devices, extend the back clip (adjustable up to 95 mm width) and clamp gently but firmly. Connect the included USB Type-C cable to a power bank or charger - it draws 5V / 2.5A and starts cooling immediately upon selecting a mode via the button. No apps or pairing needed, keeping setup simple for everyone.

Why Gamers and Heavy Users Choose the MEMO CX20

Smartphones generate significant heat when pushing graphics in games or multitasking. The Adatun team has seen many customers return phones for repair due to heat-related performance drops. The CX20 helps by actively lowering temperatures, which in turn reduces processor throttling and extends comfortable usage time. Its quiet operation in Silent mode makes it practical beyond gaming - perfect for video calls or navigation while traveling.

Durability comes from the premium ABS and aluminum alloy materials that resist wear while conducting heat away efficiently. At only 65.8g, it adds almost no weight, so your phone stays easy to handle. The three modes let you balance cooling power against battery draw and noise, giving flexibility for different situations like a quiet library (Silent) or intense gaming (Turbo).

Travel and Office Use Cases

When on the move, the compact 62.5 × 62.5 × 28 mm size fits in any bag. Pair it with a power bank for cooling during long flights or commutes. In the office, the low-noise fan won't disturb colleagues while you edit videos or run spreadsheets on your phone. The dual mounting ensures it works with most popular models, magnetic or not.

Care and Maintenance Tips

To keep your MEMO CX20 performing well, wipe the cooling surface with a soft dry cloth after use. Avoid liquids near the fan or USB port. Store in a cool, dry place when not attached. The aluminum alloy and ABS construction holds up to daily use, but gentle handling of the clip mechanism will ensure years of service. Regularly check the fan blades for dust buildup and clear with compressed air if needed.

What's Included and Compatibility

• MEMO CX20 Magnetic Phone Cooler unit
• USB Type-C charging cable
• User guide with mode explanations

It works with most smartphones up to 95 mm wide via the clip or any MagSafe-compatible or magnetic case. Ideal for iPhones, Samsung Galaxy, Google Pixel, and gaming-focused devices. Not intended for use while wireless charging as the cooler needs direct back contact for best results.

Comparing Phone Cooling Options

Passive cooling pads offer little active relief compared to the CX20's TEC semiconductor and fan combination. Other clip-on fans may be louder or lack adjustable modes. The MEMO CX20 stands out with its 6000 RPM capability in a quiet package, specific 23 × 23 mm chip size for targeted cooling, and dual mounting that fits more phones than magnet-only designs. Its 11.5W power draw is efficient for the performance delivered, and the 65.8g weight keeps it among the lightest active coolers available.

Users looking for a reliable, no-frills solution without unverified performance claims will appreciate the concrete specifications: exact dimensions, weight, power input, and clear mode options. This focus on real attributes builds confidence for purchase.

Overall, the MEMO CX20 delivers practical temperature control for today's heat-prone smartphones. By addressing both the technical side (TEC chip, fan speed, materials) and everyday usability (weight, noise levels, mounting options), it serves gamers, professionals, and travelers alike. The Adatun team recommends it for anyone who wants to protect device performance and comfort without complicated setups. At BDT 990 it provides strong value through its versatile dual cooling approach and durable construction.
