Who Should Buy This#
The Logitech K380 hits a sweet spot for people who use more than one device daily and want a single keyboard that works with all of them. It delivers seamless multi-device switching, cross-platform compatibility, and a 2-year battery life that premium keyboards struggle to match.
Perfect for:
- Remote workers who switch between a work laptop and personal tablet throughout the day without reaching for a different keyboard
- Students who type notes on a Chromebook in class and then switch to an iPad for reading and annotation at home
- Minimalists who want one compact keyboard on their desk instead of dealing with multiple input devices cluttering the workspace
- Mobile professionals who need a lightweight travel keyboard that pairs instantly with a phone, tablet, or hotel business center PC
Design & Build Quality#
The K380 has a distinctive look thanks to its round, concave keycaps — a departure from the rectangular keys on most keyboards. The rounded shape is not just aesthetic. Each key has a scooped center that guides your fingertips into position, reducing mistypes after a short adjustment period.
At 423 grams and just 16mm thick, the K380 slips into a laptop bag or backpack without adding noticeable weight. The matte plastic shell resists fingerprints and feels solid despite the light weight. Logitech has sold it in several colorways over the years; the version linked here is the Dark Grey 920-007558. One thing to know before you buy: Logitech's US shop no longer carries a K380 product page at all — the old product URL now redirects to the keyboards category — while the newer Pebble Keys 2 does have one. Logitech publishes no discontinuation notice, and the keyboard is still stocked and selling on Amazon, but it is no longer a current line on Logitech's own storefront.
Key Features#
Easy-Switch: Three Devices, One Keyboard#
The headline feature is Easy-Switch. Three dedicated buttons at the top of the keyboard (F1, F2, F3) each store a Bluetooth pairing. Press F1 and you are typing on your MacBook. Press F2 and you are on your iPad. Press F3 and you are responding to messages on your phone. Logitech publishes no switching-latency figure, but each channel has its own LED so you always know which device you are typing to.
This is genuinely useful in practice. You can draft an email on your laptop, tap F2 to reply to a Slack message on your tablet, and tap F3 to answer a text on your phone, all without lifting your hands off the keyboard.
Cross-Platform Key Mapping#
The K380 automatically detects your operating system and remaps keys accordingly. On macOS, the bottom-left key functions as Command. On Windows, it becomes the Windows key. On iPadOS, keyboard shortcuts like Cmd+Space for Spotlight work out of the box. You do not need to install drivers or configure anything — it just works.
The function row also adapts. Media controls, brightness, and volume keys map correctly whether you are on a Mac, PC, or Chromebook, and Logitech's dedicated hotkeys cover Home, Back, app-switch and the contextual menu. This OS-aware behavior eliminates the frustrating guesswork you get with generic Bluetooth keyboards.
Logitech Flow#
The K380 is one of the keyboards that works with Logitech Flow. Pair it with a Flow-capable Logitech mouse, sold separately, and you can type, copy, paste and move files across two computers as if they were one machine. It is a niche feature, but if you already run a Flow mouse it turns a three-device keyboard into a genuine two-computer workstation.
Quiet Scissor-Switch Keys#
The K380 uses the scooped, low-profile scissor mechanism Logitech puts in its laptop-style keyboards. The keys are quiet enough for shared offices, libraries, and coffee shops without sacrificing the tactile feedback you need to type accurately.
Typing feel is subjective, but the K380 strikes a comfortable middle ground. The keys have enough resistance to prevent accidental presses but are light enough for extended typing sessions without finger fatigue. Most users adapt to the round keycaps within a day or two.
2-Year Battery Life#
Logitech rates the K380 at 24 months on 2 AAA batteries, based on an estimated two million keystrokes a year in an office environment. That is not a typo. The efficient electronics mean you can forget about battery management almost entirely, and there is a dedicated battery-status LED alongside the three Bluetooth channel LEDs.
The trade-off is that the K380 is not rechargeable — you swap in fresh AAA batteries when the time comes. For most people, buying a pair of batteries every two years is a non-issue compared to remembering to charge yet another device.
