Review: 見た目スッキリ。2年くらい毎日使用してますが今もしっかり充電してくれるので助かります。
Review: 良い点 容量も大きく、充電速度も速いので性能としては大満足です。 悪い点 商品説明を見れば分かりますが、デカくて重いので手に持って使ったりポケットに入れて使うのには向いていません。その為、本体から生えてるケーブルはあまり役に立ちません。ケーブルを忘れても使用可能(すごく不便ではありますが…)という保険的な機能と捉えた方が良いでしょう。

## Questions & Answers

**Q: 充電可能回数が想定より少ないのはなぜですか？**
A: 一般的なモバイルバッテリーが他のデバイスに供給できる電力は、通常、バッテリー容量の約60%〜70%です。 回路で発生する熱や電圧変換により、容量の約30〜40%が失われるためです。 そのため、満充電のINIU 20000mAhモバイルバッテリーからは、お客様のデバイスに実質12000〜14000mAhが供給されます。

**Q: 充電可能回数はどのように計算できますか？**
A: 業界標準の計算式：（モバイルバッテリー容量 × 65%）÷ デバイスのバッテリー容量 ≈ 充電可能回数 例：（20,000mAh モバイルバッテリー × 0.65）÷ 3279mAh（iPhone14のバッテリー容量）≈ 4.0回

**Q: 最大出力で充電されないことがあるのはなぜですか？**
A: INIUモバイルバッテリーは、過熱を防ぐためのスマート温度チェックシステムを搭載しており、出力を自動で調整します。 お客様のデバイスの充電残量が少ない時は最大出力で充電し、その後、デバイスのバッテリーを保護し効率を高めるために出力を調整します。

**Q: 飛行機内への持ち込みは可能ですか？**
A: 当社の20000mAh（定格エネルギー74Wh）モデルは、日本国土交通省およびTSA（米国運輸保安庁）の機内持ち込み規制（100Wh以下≈27,027mAh以下）を満たしているため、機内へのお持ち込みが可能です。 ※ ご搭乗の航空会社によって規定が異なる場合がありますので、詳細は各航空会社にご確認ください。

**Q: ※【NEW】中国でのご利用について※**
A: 中国からのご出国時（中国国内線・国際線を問わず）は、CCC（中国強制製品認証）マークのないモバイルバッテリーのお持ち込みが禁止されています。 INIU製品にはCCCマークが付いておらず、中国国内の空港からお乗りになる際は、没収されるリスクがありますのでご注意ください。 ※ 認証取得に向けた手続きは、現在取り急ぎ進行中。 ※ 日本など中国国外から中国へのフライトでは、この規制の対象とはなりません。 ※ 中国の高速鉄道（高铁）では、現時点（2025年10月）ではご利用いただけます。
