10 Best Foldable Keyboards 2025 in the United States

The ProtoArc Foldable Bluetooth Keyboard, model XK01, is designed with portability and functionality in mind. Its full-size 105-key layout, including a numeric keypad, makes it suitable for extensive typing tasks, whether you're working on a laptop, tablet, or smartphone. The keyboard folds down to a compact size, making it easy to carry in a briefcase or laptop bag, which is perfect for users who need to type on the go, such as business travelers or students. It weighs only 10.5 ounces, adding to its portability without being cumbersome to carry around.

The scissor-switch keys provide a quiet and responsive typing experience, mimicking the feel of a laptop keyboard, which is a significant advantage for those who type extensively. The keyboard can sync with up to three devices simultaneously via Bluetooth, which is quite convenient if you need to switch between your laptop, tablet, and phone quickly. This flexibility is enhanced by its compatibility with various operating systems, including Windows, iOS, Mac OS, and Android. The built-in rechargeable battery offers an impressive standby time of up to five months on a single charge, reducing the need for frequent recharging and adding to its convenience.

The keyboard has some limitations. The build quality, while generally good, might not be as sturdy as some higher-end models. The keyboard backlighting is limited to a single color, which might not appeal to those who prefer customizable lighting options. Additionally, while the 12 multimedia shortcut keys are a useful feature, they require pressing the Fn key in combination with other keys, which can be a bit cumbersome for some users. In summary, the ProtoArc Foldable Bluetooth Keyboard is a solid choice for those needing a portable and versatile typing solution, particularly for on-the-go use. Its strengths lie in its portability, connectivity, and battery life, while its potential drawbacks include its build quality and non-customizable backlighting.

The keyboard supports Bluetooth connectivity and can pair with up to three devices, maintaining stable connectivity within a 33ft range.

A significant advantage is its rechargeable battery, which can provide up to 150+ days of standby time after just 2 hours of charging via a Type-C cable.

However, the compact size might cause some inconvenience for those accustomed to full-sized keyboards, making it less ideal for extensive typing sessions. The key layout and typing comfort are optimized for brief use, which is particularly beneficial for mobile phone and tablet users. In terms of durability and build quality, the use of Acrylonitrile Butadiene Styrene and PU leather indicates a robust design. Additional features include shortcut keys for multimedia functions, although it doesn't fully replicate the experience of a standard office keyboard.
