Overview

The Logitech Wireless Keyboard K270 is a full-size 2.4GHz wireless keyboard that keeps a numeric keypad while staying fairly slim. Setup is plug and play: you put the bundled Unifying receiver into a USB port and start typing, with no pairing routine or driver install required. That makes it a practical pick for a desktop where you want fewer cables, or as an external input for a laptop that lives on a stand.
The layout is a 108-key Japanese arrangement with a 19mm key pitch and 3.2mm key travel, and the keys themselves are membrane type. The body measures 20.5mm high, 435.5mm wide and 137.5mm deep, so it is wide but not tall, which keeps the front edge low on a desk. Power comes from two AAA batteries, and battery life is quoted at up to two years. An on/off switch plus automatic standby helps limit drain when the board sits idle.
Positioning is clearly entry level. This is not a board sold on exotic switches or per-key lighting; it is sold on easy placement, long battery life and a familiar layout at a low price.

Connectivity & Compatibility

Connection is handled by the included Unifying receiver over 2.4GHz, with an operating distance quoted at up to 10m. Because it does not rely on Bluetooth, it also works on desktops that have no Bluetooth radio at all.
The listed supported operating systems are Windows XP, Windows Vista and Windows 7, which is an old list, so check current OS support information before you buy. The keyboard offers eight one-touch hotkeys for things like volume up and down or launching a browser. Logitech also states a spill-resistant design tested against up to 60ml of liquid and keys tested to five million strokes, which is worth knowing for everyday desk use.

Product Info

The K270 dates back to an April 2011 release and has stayed in the lineup for a long time. Street pricing sits in the low thousands of yen, placing it in the entry tier for a full-size wireless keyboard with a Japanese layout. Weight is listed at about 472 g. If you want a premium typing feel or multi-device switching, this is not that product; if you want a cheap, dependable board that just works, it fits.

Best Use Cases

  • Desk users who want to cut cable clutter: the receiver-based setup and long battery life suit a stationary desktop, but the membrane feel will disappoint anyone chasing a mechanical typing experience.
  • People who need a numeric keypad for office or accounting work: the 108-key Japanese layout and 19mm pitch keep number entry comfortable, though the wide body is a poor match for anyone who wants a portable board.
  • Anyone adding a low-cost wireless input to a secondary or shared family PC: the price tier makes it easy to justify as a spare, but people who want Bluetooth switching across several devices should look elsewhere.
