Review: 前にこれより高額の最新モデルのスマホクーラーを買いましたが高出力充電器だと動かないわ買って半年で動かなくなるわでどうせすぐ壊れるならとこっちを買いましたがぜーんぜんこっちでええやんけ。 半年以上経ってもバリバリ冷やしてくれるし充電器の相性も無いし。 今使ってるの壊れたらまた買います。
Review: 半信半疑で買いましたが、めちゃくちゃ冷えます。 謎のゲーミングっぽいライトは、ボタンをカチカチ！で消す設定にできるので問題なし。 アプリとかは使ってません。 まあちょっと重いけど、それは仕方ないのかな。もう少し軽量だとうれしい。 耐久性はどうかな、まだ1ヶ月程度ですが今のところは全く問題なしです。

## Questions & Answers

**Q: Why the fan doesn't spin when you connect the heatsink to the charger?**
A: For the radiator to work properly, it must be connected to a charger that has at least 15W of power.After connecting the charger, the switch on the side of the radiator is also required to turn on to make the fan rotate.

**Q: Can I connect the FunCooler 4 cooler to a mobile power?**
A: You can. However, FunCooler 4 coolers are 15W, so you need to use a mobile power source of 15W or higher to ensure proper operation.

半信半疑で買いましたが、めちゃくちゃ冷えます。 謎のゲーミングっぽいライトは、ボタンをカチカチ！で消す設定にできるので問題なし。 アプリとかは使ってません。 まあちょっと重いけど、それは仕方ないのかな。もう少し軽量だとうれしい。 耐久性はどうかな、まだ1ヶ月程度ですが今のところは全く問題なしです。

### ⭐⭐⭐⭐⭐ Review
*by 卵***き on October 9, 2025*

消費電力が多いですが想像以上に冷えます。 具体的に書くと、最弱設定でもスマホとこのクーラーの間に結露が発生するので使用後は必ずクーラーを外してスマホとクーラーの水分を拭き取った方が良さそうです。 クーラーは熱くなりますが、スマホはキンキンに冷えます。 磁力も強く外れにくいので、とても満足です。
