Geyes Bluetooth Keyboard Foldable Portable Foldable Wireless Keyboard Portable Pocket Size Aluminum Alloy Housing for iPhone iPad Tablet Laptop Smartphone (Black)

iPhone、iPadで満足に使えてます。説明書がわずかなので使い方(文字の切り替え、記号など)は自分で調べる必要があります。

適度な大きさでいい。漢字変換はキーボードに貼るシールであれば、いい。自作できるけど、あれば親切。

It is not said so explicitly in the description, so here it is: this model does not support USB connection. Sure, it does have a USB-C port, but it is for charging only. Based on the information within the included instruction booklet there exists a model of this keyboard with wired capabilities, but this one is not it. If you need to use it in a pre-boot environment don't waste your money and look for another option.

以前買ったBluetoothキーボードの接続がなかなかうまくいかなかったので，今回の商品には満足しています。
