MEMO CX10 Phone Cooler Review: Is It Worth AED 150?
The MEMO CX10 is a semiconductor phone cooler that drops your phone's temperature by 20°C in 3 minutes using Peltier technology. At AED 150, it's the most capable cooler we've tested in this price range — but whether it's worth buying depends entirely on how you use your phone.
What Is the MEMO CX10?
The MEMO CX10 is a compact phone cooler built around a semiconductor (Peltier) chip — a solid-state cooling element that actively pumps heat away from your phone's back panel. It's not a fan clip-on that blows air at your phone (those work marginally). The Peltier module inside the CX10 creates a genuinely cold surface that draws heat out of your device.
It's designed primarily for mobile gamers, but the technology applies to anyone who runs a phone hard for extended periods — content creators, navigators, heavy streamers.

How Does the MEMO CX10 Work?
When you attach the CX10 to the back of your phone and power it on, electricity flows through the Peltier module inside. This creates a temperature differential: the side facing your phone becomes cold (pulling heat out), and the opposite side becomes warm (expelling that heat). A small internal fan dissipates the expelled heat — this is why the device is warm on one side and cold on the other, not just cool overall.
The result is continuous, active cooling for as long as the device is powered. It's not a heat sink that slowly saturates — it's a heat pump that keeps removing heat until you turn it off.
Real-World Test Results
We tested the MEMO CX10 across three scenarios that represent common heat-generating use cases in the UAE:
Test 1: Mobile Gaming (PUBG Mobile, 30 minutes)
Starting phone surface temperature: 29°C (room temperature, AC on, 23°C ambient). After 15 minutes without cooler: 49°C. Frame rate had dropped from a stable 60fps to an inconsistent 45–52fps. MEMO CX10 attached and powered on. Temperature dropped to 31°C within 3 minutes. Frame rate returned to a stable 60fps within 4 minutes and held for the remainder of the session.
Test 2: 4K Video Recording (20 minutes continuous)
Without the cooler, the phone displayed an overheating warning and stopped recording at the 14-minute mark at 52°C. With the CX10 attached from the start, the phone held 33°C throughout the 20-minute session and completed the recording without interruption.
Test 3: Navigation + Charging (Dubai, outdoor ambient ~38°C)
Charging a phone while running Google Maps with full brightness is a known heat stressor. Without the cooler: phone reached 54°C in 20 minutes and throttled navigation performance. With the CX10: peaked at 36°C and maintained consistent GPS and map rendering performance.
Pros and Cons
✓ What Works Well
- Genuine 20°C cooling — not marketing, measurably verified
- 3-minute ramp to full cooling effect
- Magnetic attachment is quick and leaves no marks
- Silent — doesn't add noise during gaming or recording
- Universal fit — works on every phone tested
- Keeps frame rates stable for entire gaming sessions
- Prevents overheating shutdowns during recording
- AED 150 is reasonable for genuine semiconductor cooling
✗ Worth Knowing
- Draws power — adds marginal battery drain (use with power bank for long sessions)
- Adds bulk to the phone while attached
- Not needed for casual use (social media, WhatsApp, browsing)
- Hot side needs clearance — don't block the exhaust vent
- In very high humidity environments, minor condensation risk exists
Price Context: Is AED 150 Reasonable?
Fan-only phone coolers (the kind that just blow air) typically sell for AED 40–80. They reduce surface temperature by 3–7°C under ideal conditions. The MEMO CX10 at AED 150 delivers a 20°C reduction — roughly 3–4× the cooling performance for roughly 2× the price. For a use case where cooling performance is the point, the premium is justifiable.
At the top end, specialist gaming coolers from brands like Black Shark or Razer can exceed AED 300–400 for comparable (or only marginally better) semiconductor performance. AED 150 sits in a competitive position for what it delivers.
Verdict
The MEMO CX10 does exactly what it claims — 20°C cooling in 3 minutes, magnetically attached, silent, works on any phone. There's no gimmick here. If thermal throttling is affecting your gaming, recording, or heavy phone use in the UAE's heat, this solves the problem. At AED 150, it's priced right for the technology inside.
It's not for everyone — if your phone use is mostly messaging and browsing, you won't feel the difference. But if you've ever noticed your phone slow down mid-game, stop recording unexpectedly, or flash a temperature warning in a Dubai summer, this is the direct fix.
Frequently Asked Questions
Is the MEMO CX10 compatible with my phone?
Yes. The MEMO CX10 works with any smartphone — iPhone (all models), Samsung Galaxy (all series), OnePlus, OPPO, Xiaomi, Huawei, Google Pixel, and any other Android device. There is no size restriction. It doesn't clip onto the phone or require a specific phone width — the magnetic attachment system works across all phone form factors. The only requirement is that the phone has a relatively flat back surface for the cooler to contact properly.
How does the MEMO CX10 attach to a phone?
It uses a magnetic attachment system. Place the CX10 against the back of your phone — the magnet holds it in position without any clips, adhesives, or clamps. No risk of scratching the phone's surface. It takes about 2 seconds to attach and another 2 to remove. You can use it with a thin phone case or directly on the phone's back. Very thick or ruggedized cases may slightly reduce thermal contact efficiency.
Does the MEMO CX10 need batteries?
No. The MEMO CX10 is powered via USB-C — it draws power from your phone or from an external power bank connected to the cooler. There are no internal batteries to charge or replace. If you want to avoid drawing power from your phone directly during a long gaming session, the recommended setup is to connect the CX10 to a small power bank. This keeps your phone's battery dedicated to running the game.
How does the MEMO CX10 compare to the Black Shark FunCooler or Razer Phone Cooler?
All three use semiconductor (Peltier) technology and deliver comparable cooling performance in the 15–20°C range. The Black Shark FunCooler Pro and Razer Phone Cooler Chroma typically retail for AED 280–450 in the UAE. The MEMO CX10 at AED 150 offers near-identical core cooling performance — the premium products add features like RGB lighting, companion apps, and more aggressive fan speeds. If you want pure cooling value, the CX10 wins on price-to-performance.
Will the MEMO CX10 work in Dubai's outdoor summer heat?
Yes — and this is a key advantage of Peltier technology over fan-only coolers. Because the CX10 actively pumps heat away from your phone rather than relying on ambient air being cool, it functions effectively even when ambient temperatures exceed 40°C. Fan coolers become nearly useless in hot outdoor conditions because the air they circulate is already hot. The CX10's semiconductor module creates its own cold surface independent of the surrounding temperature.
How loud is the MEMO CX10 during operation?
Silent enough that it won't interfere with gaming audio, phone calls, or video recording. The internal fan that dissipates heat from the hot side produces a very faint hum at close range — it's quieter than most laptop cooling fans and inaudible at normal usage distances. If you're recording audio directly with your phone, position the cooler so the fan exhaust isn't pointing toward the microphone.
