10 Best Foldable Keyboards 2025 in the United States

The ProtoArc Ergonomic Foldable Keyboard is designed with portability and comfort in mind, making it ideal for travelers and those who work on the go. Its ultra-slim and 360° foldable design allows it to fit easily into a backpack or briefcase, and the strong magnetic closure prevents accidental openings. This keyboard's ergonomic split keyset design aims to reduce wrist strain and improve typing posture, though it may take some time to get used to if you're accustomed to traditional keyboards.

It is built with aluminum for durability and has a stylish leather appearance that complements various devices. Connectivity is a strong point, as you can pair it with up to three devices simultaneously and switch between them easily. It's compatible with iOS, Android, Windows, and Mac OS, covering most tablets, smartphones, laptops, and PCs.

The battery life is quite decent, with a Type-C rechargeable battery offering up to 250 hours of standby time, which is suitable for short trips. On the downside, the compact design with 64 keys might feel cramped for users who prefer full-sized keyboards. Some users may also find the initial adaptation period to the ergonomic layout slightly challenging. Despite these minor drawbacks, the ProtoArc Ergonomic Foldable Keyboard is a solid choice for those seeking a portable and ergonomic typing solution.

The ProtoArc Foldable Keyboard and Mouse combo is a solid choice for anyone needing a portable, travel-friendly keyboard that doesn’t sacrifice typing comfort. Its true full-size layout with 105 keys is impressive for a foldable design, making it easier to type without constantly adjusting to smaller keys. It is compatible with multiple operating systems including Windows, Mac, iPadOS, and Android, which makes it versatile for users switching between devices. You can connect up to three devices at once using Bluetooth and 2.4G wireless, and quickly switch among them, which is convenient for multitasking.

The keyboard and mouse are both rechargeable via USB-C, and their long standby battery life (150 days for the keyboard, 200 days for the mouse) means less worry about frequent charging. The quiet scissor-switch keys and adjustable DPI mouse contribute to a comfortable and unobtrusive work environment. The included hard carrying case and collapsible stand enhance portability and device support during use. However, the fold hinge does not lock firmly, so it’s best to use the keyboard on flat surfaces to avoid instability. At nearly 2 pounds, it is portable but not ultra-light, so it’s more suited for those who prioritize full-size typing over minimal weight. Some users might miss a backlight feature for working in low-light conditions.

This combo suits business travelers and anyone needing a reliable, multi-device foldable keyboard and mouse without compromising on key size or functionality.

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.
