Best Multi-Device Value1 of 5
Dell KM720 Multi-Device Wireless Keyboard and Mouse on Amazon (opens in a new tab)
The KM720 adds Bluetooth 5.0 to the receiver, 12 programmable F-keys and a seven-button mouse up to 4000 DPI.
Best for

Skip if
- Look at the others if this bothers you: no backlighting.
Why we like it
It is Dell's multi-device option below the KM900. It matches the KM520 on keyboard battery rating (up to 36 months). On maximum mouse sensitivity it trails the group at 4,000 DPI, while the KM900 offers 8,000 DPI.
A seven-button mouse mouse or pointer is unique to it among these picks, while the KM526 uses a symmetrical mouse mouse or pointer. It also offers mouse sensitivity steps of 1000, 1600, 2400 and 4000 DPI. The receiver is USB-A; a USB-C-only laptop needs an adapter or hub. On price it sat fourth of 5, between the cheaper KM555 and the pricier KM900, at the time of writing.

Best for Video Calls2 of 5
Dell Premier Collaboration Keyboard and Mouse KM900 on Amazon (opens in a new tab)
Dell's KM900 is a Zoom-certified set with collaboration keys and a backlight that wakes as your hands approach.
Best for
- People on calls most of the day
Skip if
- Skip it if you need to know its keyboard battery rating before buying; the maker doesn't publish one.
Why we like it
Its mouse tracks on glass from 800 to 8000 DPI. Its 8,000 DPI maximum mouse sensitivity is the highest here; the KM526 comes next at 6,000 DPI. You get a full-size with scissor keys keyboard layout here, which sets it apart from the KM555 and its a compact silent keyboard layout.
No other pick in this guide offers a track-on-glass mouse mouse or pointer; compare the KM520, which has a three-button mouse mouse or pointer. The receiver is USB-A; a USB-C-only laptop needs an adapter or hub. At our last price check it topped the group, with the KM720 the nearest cheaper option. If you want a confirmed keyboard battery rating, look to the KM526 instead: it runs for up to 48 months, while this one gives no figure.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Power
- We compared listed battery ratings or rechargeable capacity.
- Layout and mouse
- We noted the keyboard layout, number pad and mouse shape.
- Extras
- We checked hotkeys, lighting, anti-ghosting and noise claims in each listing.
- Connection
- We recorded each set's receiver, Bluetooth or wired connection.
What to Look for in a Dell Wireless Keyboard and Mouse
Key buying criteria so you get the right fit the first time.
Receiver, Bluetooth or cable
A USB receiver pairs out of the box and works in the BIOS; Bluetooth frees a port but needs the PC to support it. Tri-mode sets add a cable for charging and play.
Match the connection to the ports your PC or laptop actually has.
Battery rating and power type
AA and AAA sets list battery life in months; rechargeable sets list hours or days per charge. Long ratings suit office desks, while rechargeable sets suit people who would rather plug in than buy batteries.
Key and click noise
Membrane and silent-switch sets are quieter than mechanical blue or red switches. If you share a room or take calls, look for sets that name a silent or low-noise design.
Check the mouse shape
Many combo mice are small and ambidextrous. If you have large hands or want side buttons, check the mouse description; a right-handed contoured mouse or one with more buttons may suit you better.
Full-size or compact
A full-size board keeps the number pad for spreadsheets. A 60% to 75% board frees room for wide mouse sweeps, which matters more in games than in office work.
Operating system support
Hotkeys and software often target Windows. If you use macOS or ChromeOS, look for a listing that names it, and expect some media keys to behave differently.

Frequently Asked Questions
Do the keyboard and mouse share one receiver?
In most receiver-based combos, yes; the listing usually says one receiver pairs both. Keep it safe, since replacements are brand-specific.
Can I replace just the mouse later?
Yes. Any mouse works alongside the keyboard; you simply lose the shared receiver for the new mouse.
Do wireless combos lag?
For typing and everyday use, input delay from a 2.4GHz receiver is not noticeable for most people. Bluetooth can take a moment to wake after sleep.
Rechargeable or disposable batteries?
Disposable AA and AAA sets run for months and swap in seconds. Rechargeable sets avoid buying batteries but need a cable every few days to weeks, depending on lighting.
Will a Windows combo work on a Mac?
Basic typing and pointing usually work. Some Windows keys map differently, and software may be Windows-only.
Is a wireless combo fine for gaming?
For casual play, a 2.4GHz receiver is fine. Competitive players often prefer a dedicated gaming mouse with a higher polling rate.
Bottom Line
The KM720 covers most desks with receiver plus Bluetooth and a seven-button mouse. The KM900 suits frequent video calls, the KM526 has the longest battery rating, and the KM520 is the plain choice.
If you share a room, the compact KM555 is the quiet one.
