Logitech K250 Compact Wireless Bluetooth Keyboard, Graphite
States plainly: no USB receiverThe listing says the quiet part out loud: Bluetooth only, no USB receiver.

Apple Magic Keyboard, US English, Bluetooth
Connection and layout, nothing elseTwo facts: how it connects, and what layout it has. That is the entire listing. No battery figure, no pairing count, no operating system list, no Bluetooth version.

OMOTON Ultra-Slim Bluetooth Keyboard, White

Both routes stated: Bluetooth and receiverIt is the one keyboard listing in the catalog that names both routes: Bluetooth and a Logi Bolt receiver.

Logitech MX Keys S Wireless Keyboard, Graphite
Only stated USB-C rechargingThe USB-C on this keyboard is for recharging, and the listing says so.

Logitech K400 Plus Wireless Touch Keyboard, Black
Pointing device built inThe pointing device is built into the keyboard, which changes the arithmetic on the rest of the desk: whatever this occupies, it occupies once, for both jobs.

What the listing gives you
- +A touchpad is built in, so no separate mouse is needed for it.

- +Media controls are stated.
- +One device covers two jobs on the port count.

Logitech K270 Full Size Wireless Keyboard, Black
