Details

Overview

The Bahusuo EW-RB024 is a foldable wireless keyboard designed for users who need a compact typing solution on the go. It supports both Bluetooth 5.0 and 2.4GHz USB wireless connections, making it compatible with a wide range of devices including those without Bluetooth. The keyboard features a standard JIS Japanese layout, supporting both romaji and kana input methods.
When folded, the keyboard measures just 184.3 x 114.9 x 19.4 mm and weighs 303.6g, making it easy to slip into a bag. The magnetic folding mechanism keeps it securely closed, while the included leather cover doubles as a stand for smartphones and tablets. This makes it a practical companion for business trips and travel.

Connectivity & Compatibility

The EW-RB024 offers dual connectivity via Bluetooth 5.0 and a 2.4GHz USB wireless receiver. You can pair up to three devices simultaneously — two via Bluetooth and one via the USB receiver. Switching between devices is handled with the Fn + A/S/D keys, allowing quick transitions between a PC, tablet, and smartphone.
Supported operating systems include Windows, macOS, and iOS. The 2.4GHz receiver is particularly useful for connecting to devices that lack Bluetooth but have a USB-A port. This flexibility makes the keyboard suitable for users who juggle multiple devices throughout the day.

Product Info

This keyboard integrates a multi-touch trackpad and a numeric keypad into a foldable form factor. The trackpad supports left and right clicks and can be locked or unlocked with Fn + Space. The built-in numeric keypad speeds up data entry tasks in spreadsheet and accounting software.
The keys use a scissor-switch mechanism, providing a light touch with quiet operation — suitable for offices and public spaces. Twelve multi-function keys include volume and media controls for quick access. The internal battery charges via Type-C in about 2-3 hours and provides up to 60 hours of continuous use. An auto-sleep function activates after 20 minutes of inactivity, and a power switch helps conserve battery when not in use. LED indicators show pairing status, power state, and battery level.

Best Use Cases

Business travelers who need to type on a laptop or tablet in hotels, airports, or client sites. The compact folded size and the leather cover's stand function make it easy to set up a workspace almost anywhere.
Users who prefer to travel without a separate mouse. The built-in trackpad with click support handles basic cursor work, though it is not ideal for precision tasks like photo editing or CAD work.
People who switch between multiple devices during the day. With three paired devices and one-touch switching via Fn keys, you can move from a desktop PC to a tablet to a phone without re-pairing. If you only use a single device, this capability may go unused.
