10 Best Foldable Keyboards 2025 in the United States

The SIKAI CASE Foldable Bluetooth Keyboard is a lightweight and compact option designed for people who need a portable keyboard for travel or casual use with tablets, phones, or laptops. Its foldable aluminum alloy design makes it easy to carry in a bag or even a jacket pocket, measuring about 8 by 4 inches when unfolded and weighing just 250 grams. It connects via Bluetooth and supports multiple operating systems like iOS, Android, Windows, and MacOS, providing stable and fast pairing.

The keyboard has 60 keys with a scissor-switch mechanism, which offers a quiet and comfortable typing experience, though the keys are smaller than regular keyboards, which might take some getting used to especially for those with larger hands. Battery life is a strong point, offering up to 45 hours of continuous use and around 90 days on standby from a quick 2-hour charge. It also includes an energy-saving mode that automatically sleeps after inactivity. One handy feature is the built-in magnetic stand, which can hold tablets or phones up to 11 inches, though it is not very strong and doesn't support thicker device cases well. This stand adds convenience for reading or typing on the go but has limited stability.

The build quality is solid thanks to its aluminum body, making it durable for travel. However, it doesn’t include a numeric keypad, and the smaller size means it’s better suited for simple typing tasks rather than heavy data entry. This keyboard is a good fit for travelers, students, or anyone needing a compact, rechargeable Bluetooth keyboard that is easy to carry and use with multiple devices, but those needing full-sized keys or strong device stands might want to consider other options.

The ProtoArc XK01 Plus is a tri-fold, full-size Bluetooth keyboard designed with portability in mind. It folds down to a compact size that easily fits in a bag, making it a great travel companion for those who need a reliable keyboard on the go. It includes a 105-key layout with a number pad and shortcut keys, similar to a regular laptop keyboard, which helps maintain comfortable and accurate typing. The backlit keys with three brightness levels are useful for typing in dim environments, offering some eye comfort during nighttime use.

Connectivity is strong thanks to Bluetooth 5.1 with support for up to three devices, so switching between your phone, tablet, and laptop is smooth and hassle-free. The rechargeable battery stands out, offering up to 150 days on standby, and it smartly powers off when folded or inactive to save energy. However, at 1.36 pounds, it’s a bit heavier than some ultra-portable keyboards, and while the build quality is decent, it may not feel as sturdy as larger, stationary keyboards. The single-color backlighting might also feel limited if you prefer more vibrant or customizable lighting.

This keyboard is well-suited for travelers and mobile users who prioritize a full-size layout and convenience but might not be the best fit if you want the lightest or most rugged folding keyboard available.

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.
