Review: Qi2認証を謳うモバイルバッテリーの中で最もリーズナブルだったので購入しました。 マグネットは十分に強く、雑にカバンの中に入れておいてもスマホから外れることはありませんでした。 充電速度はかなり速く、20分で12%→45%(+33%)、そのまま30分で59%(+47%)でした。 有線での充電の方は、電力表示ケーブルで測ったところしっかりPD20W出ていました。 公式サイトに製品登録すると2年保証になるようです。故障の際にはしっかり対応してくれると信じましょう。
Review: まずは、翌日配送してくれた配達員の方、夜、寒い中しっかりと配達していただきありがとうございました。 商品はしっかりとした作りで、iPhone15pro maxにばっちり使え、ひとまず安心しました。 ワイヤレス充電、めちゃくちゃ便利ですね。ケーブル無いだけで、見た目も使いやすさも別格です。 充電速度もMagSafeのワイヤレス充電でも、結構早く充電されており、満足してます。 あとは、耐久性や膨張の有無が気になるところですが、そのあたりは追って検証したいと思ってます。とりあえず、現時点買いです。

まずは、翌日配送してくれた配達員の方、夜、寒い中しっかりと配達していただきありがとうございました。 商品はしっかりとした作りで、iPhone15pro maxにばっちり使え、ひとまず安心しました。 ワイヤレス充電、めちゃくちゃ便利ですね。ケーブル無いだけで、見た目も使いやすさも別格です。 充電速度もMagSafeのワイヤレス充電でも、結構早く充電されており、満足してます。 あとは、耐久性や膨張の有無が気になるところですが、そのあたりは追って検証したいと思ってます。とりあえず、現時点買いです。

ワイヤレス充電で発熱が気になる人はこれを買えばいい。 発熱しないわけではないが，他製品に比べ明らかに発熱量が少ないように感じる。 ただやはり、5000mAなのでスマホ0.8回分ほどしか充電できないため，大容量がらしい人にはオススメできないと感じる。
