Folded, it shrinks to something smaller than an iPad mini and slips into a slim bag or a jacket pocket; opened, it becomes a full JIS-layout board with a large reverse-L Enter key and a dedicated number pad. At 317g it stays light enough to carry every day, which makes it a natural companion for cafe sessions, train rides and hotel-room work. Typing relies on a pantograph mechanism with a 19mm key pitch, echoing the feel of a notebook PC. A silent hinge lock holds the fold flat so the board does not wobble even on your lap, and a small display shows the current connection mode and battery level at a glance. Wireless runs on Bluetooth 5.2, and a Type-C wired mode is available as well. The 500mAh battery is rated for up to 90 hours of use, and the PU-leather back with built-in magnets keeps the two halves together when folded. ## Connectivity & Compatibility Bluetooth 5.2 lets you pair up to three devices and switch between them with a single key press. The board works with iOS, Windows and Mac OS, so iPads, MacBooks, Surface tablets and iPhones are all fair game. For wired operation it connects over Type-C, and the bundled cable is an A-to-C type, which also means you can keep typing while charging. The layout is JIS Japanese, with 13 independent function keys. That makes it comfortable for long-form Japanese writing, blogging and coding where quick access to function keys matters. An auto-sleep feature cuts power draw when the keyboard is idle. ## Product Info The EW-NKB304 sits in the entry-to-mid range of portable folding keyboards. It will not match a desktop mechanical board for key feel, but for buyers who prioritise portability it offers a sensible balance of features and cost. ## Best Use Cases * Remote workers who type in cafes, trains or hotel rooms: the folding body and hinge lock keep the board stable on a lap, while the number pad helps with long documents. Not for anyone who wants a heavy mechanical feel at a fixed desk. * People juggling an iPad, an iPhone and a Windows laptop: three-device Bluetooth pairing and one-touch switching remove the need to carry separate keyboards. Not useful if you only ever connect to a single machine. * Data-entry and accounting tasks on the go: the dedicated number pad and reverse-L Enter fill the gap left by cramped laptop keyboards. Overkill for users who keep a full-size board permanently on the desk. ### Product Disclosure (Amazon) - Manufacturer: Ewin - Brand: ewinstore - Model: EW-NKB304 - ASIN: B0H2LCRVZF - Note: This article covers a manufacturer-made product based on Amazon listing details.
