12 min read5 products evaluated

For an everyday computer keyboard, the layout, key feel and connection matter most. These are ordered from the lowest listed price.
The order reflects battery (backlight off), paired devices and layout from maker specifications; we did not test these keyboards ourselves, and a missing battery (backlight off) is flagged, not filled in.

Our Picks
Lowest Price Here1 of 5
TECKNET 2.4G Mini Wireless Keyboard
What the TECKNET mini brings to the table is a 36-month warranty with registration, plus media hotkeys.
Best for
- Buyers who would rather put the savings elsewhere than into the Macally compact.
Skip if
- Look at the others if this bothers you: battery life of up to 12 months, behind the K400 Plus (up to 18 months).
Why we like it
It also runs for up to 12 months. On battery life it ties with the K250 at up to 12 months. It is the only pick here with a compact layout; the Macally compact has a compact (78 keys) layout instead.
No other pick in this guide offers a quiet low-travel keys key type; compare the Bnnwa multi-device, which has a low-profile keys key type. No other pick in this guide offers a 2.4GHz USB receiver only connection; compare the Bnnwa multi-device, which has a bluetooth and 2.4GHz connection. It also comes with Windows, Mac, ChromeOS and Linux support. It was the cheapest of the group when we checked; the Macally compact was the next step up.

Macally Compact Wireless Keyboard
What the Macally compact brings to the table is 12 shortcut keys, plus an on/off switch to save battery.
Best for

Skip if
- Pass if a published battery life matters; this one has none.
Why we like it
The 78-key layout drops the number pad to save desk space but keeps 12 shortcut keys for media and system functions. A 2.4GHz USB-A dongle handles the connection, so there's no Bluetooth pairing to manage. A compact (78 keys) layout is unique to it among these picks, while the K250 uses a compact with number pad layout.
You get a slim keys key type here, which sets it apart from the K400 Plus and its a quiet low-profile keys key type. It was priced above the TECKNET mini and below the K250 at the time of writing. There is no published battery life figure, whereas the K400 Plus runs for up to 18 months.
Key specs
- Layout
- Compact (78 keys)
- Key type
