The Dell WM118 is a basic, ambidextrous wireless mouse that connects through a 2.4GHz USB receiver, runs on one AA battery and tracks at 1000 DPI. It suits students, office users and laptop owners who want a plug-and-play mouse that works without software. It is not meant for gaming, heavy design work or people who want Bluetooth, a rechargeable battery or extra buttons.
Our short answer: the WM118 is a sensible low-fuss choice for everyday browsing, documents and spreadsheets, provided your laptop has a free USB-A port or you have an adapter. Some details on the Amazon.in listing do not match Dell’s own datasheet, so read the comparison table below before you buy.
This guide is based on Dell’s official WM118 datasheet, the Amazon.in listing and official pages for the alternatives, checked on 17 October 2026. We have not tested the mouse, so there are no hands-on impressions here.
Quick verdict
- Best for: home and office users, students and anyone who wants a simple second mouse for a laptop bag
- Skip if: you play games, need adjustable DPI or side buttons, want Bluetooth, or your laptop has only USB-C ports and you do not want an adapter
- Key strengths: plug-and-play setup with no drivers, ambidextrous shape, long rated battery life on a single AA cell, broad OS support listed by Dell
- Key limitations: a fixed 1000 DPI sensor, a basic button layout, a receiver that takes a USB-A port, and listing details that conflict with Dell’s datasheet
Dell datasheet vs Amazon.in listing
The table below puts Dell’s official datasheet next to the Amazon.in listing. Where they disagree, we treat Dell’s datasheet as the more reliable source, but you should check the listing and the box when your mouse arrives.
| Specification | Dell WM118 datasheet | Amazon.in listing |
|---|---|---|
| Connection | 2.4GHz wireless, USB RF dongle | 2.4GHz with USB nano receiver |
| Sensor | Optical LED | Optical |
| Resolution | 1000 DPI | 1000 DPI in the title and technical details, but one bullet says 1600 DPI |
| Buttons | 3 | 4 |
| Scroll wheel | Mechanical | Not stated |
| Battery | 1 x AA | 1 x AA, included |
| Rated battery life | Up to 18 months (varies with usage) | 12 months |
| Weight | 57.8 g without battery | 54 g |
| Dimensions | 3.8 x 10.4 x 5.8 cm | 9.5 x 5 cm (length x width) |
| Wireless range | Not stated | 10 m |
| Operating systems | Windows 7, 8.1, 10 and 11, macOS, Linux, Ubuntu, ChromeOS and Android | Lists Mac with macOS 10.12 Sierra as the minimum |
| Setup | Plug and play, no software or drivers | Plug and play |
| Shape | Ambidextrous | Ambidextrous |
| Colour | Black | Black |
| In the box | Not stated | Mouse, battery and dongle |
The 1600 DPI line on the Amazon.in listing conflicts with both the listing’s own title and Dell’s datasheet, which say 1000 DPI. We think it is a listing error. The button count also differs: Dell lists three buttons, which normally means left, right and a clickable scroll wheel. The listing says four. Plan around three until you see the mouse yourself.

What 1000 DPI means for everyday use
DPI (dots per inch) describes how far the pointer moves on screen for each inch you move the mouse. A higher number moves the pointer further with less hand movement. At 1000 DPI, the WM118 is in the typical range for office mice. On a laptop screen or a single Full HD monitor, it should feel natural, and you can fine-tune the speed in your operating system’s pointer settings.
- Windows 11: Settings, then Bluetooth and devices, then Mouse, then adjust Mouse pointer speed.
- macOS: System Settings, then Mouse, then adjust Tracking speed.
- ChromeOS: Settings, then Device, then Mouse and touchpad, then adjust Mouse speed.
The WM118 has no DPI button, so there is no on-the-fly switching. That is fine for spreadsheets and browsing. On a large 4K or ultrawide monitor, you may need to raise the OS pointer speed, and gamers or designers who want precise, switchable sensitivity should look at a different class of mouse.
2.4GHz receiver: strengths and the USB-C catch
A USB receiver (often called a dongle) is the simplest kind of wireless connection: plug it in and the mouse usually works within seconds, with no pairing. The downside is that it occupies a USB-A port.
Many thin laptops and MacBooks now have only USB-C ports. If yours does, you will need a small USB-C to USB-A adapter or a hub. Dell’s datasheet does not mention Bluetooth, so the WM118 cannot connect without its receiver. If you lose the receiver, the mouse will not work, so store it safely when you pack the laptop.
If the pointer lags or skips
- Move the receiver to a port on the other side of the laptop, away from USB 3.0 drives, as those can interfere with 2.4GHz signals.
- Use a short USB extension cable to bring the receiver closer to the mouse if your PC is under a desk.
- Replace the AA battery, because weak cells often cause stuttering before the mouse stops completely.
- Avoid glossy or glass surfaces, which optical sensors often track poorly. A plain mouse pad helps.
Battery life: 12 or 18 months?
Dell’s datasheet rates the WM118 for up to 18 months on a single AA battery, with a footnote saying real life depends on usage and computing conditions. The Amazon.in listing title says 12 months. Either way, this is a mouse you rarely need to think about. A few practical points will help you get the most out of it.
- Use a fresh alkaline AA, or a good-quality rechargeable NiMH AA if you prefer.
- Remove the battery if the mouse will sit unused for months, to avoid leakage.
- Keep a spare AA in your laptop bag, so a flat battery does not leave you without a mouse.
Shape and comfort
The WM118 has a symmetrical, ambidextrous shape, so left-handed users can use it without fighting a right-hand contour. Dell gives its dimensions as 3.8 x 10.4 x 5.8 cm and its weight as 57.8 g without the battery. That is a compact, light mouse suited to travel and smaller hands. People with large hands, or anyone using a mouse for eight hours a day, may find a fuller, right-hand-sculpted mouse more comfortable over long sessions.
Who should buy it, and who should look elsewhere
Good fit: students, home users and office staff who want a reliable no-setup mouse for a laptop or desktop, left-handed users, and anyone replacing a lost or failing basic mouse. Our work-from-home desk setup guide covers keyboards and monitors to pair with it.
Look elsewhere: gamers, designers who need precise sensitivity control, people who switch between several devices, people with USB-C-only laptops who dislike adapters, and anyone who wants quiet clicks. Dell does not market the WM118 as a silent mouse.
Alternatives worth comparing
- Logitech M185: another basic 2.4GHz mouse with a USB nano receiver. Logitech rates it for up to 12 months on one AA battery and up to 10 metres of range, and lists Windows, macOS, ChromeOS and Linux support.
- Logitech M221 Silent: a compact ambidextrous mouse built around quieter clicks, using a 2.4GHz USB receiver and a 1000 DPI optical sensor. See our Logitech M221 Silent review for its noise-reduction claim and limits.
- A Bluetooth mouse: if your laptop has only USB-C ports, a Bluetooth mouse avoids the adapter altogether, at the cost of pairing and sometimes slower wake-up.
What to check before you order
- Variant: confirm the listing reads “Dell WM118 Wireless Mouse … Black” with the USB nano receiver. Do not confuse it with Dell’s other mice that have similar names.
- Ports: make sure you have a free USB-A port or a USB-C to USB-A adapter.
- In the box: the listing says it includes the mouse, an AA battery and the dongle. Find the receiver before you throw away the packaging.
- Warranty in India: Dell’s datasheet lists a 3-year warranty, but it is a regional document, and terms vary by country and seller. Check the warranty on the Amazon.in listing and keep your invoice for claims.
- Buttons: if you specifically need four buttons, check the product photos carefully, because Dell lists three.
Once you have checked those, see the Dell WM118 (Black) on Amazon.in.
How to set up the Dell WM118
- Open the battery cover on the underside and insert the AA battery, matching the plus and minus marks.
- Remove the USB receiver from the packaging.
- Plug the receiver into a USB-A port on your PC or laptop.
- Move the mouse. Windows, macOS, ChromeOS and Linux load a standard driver automatically, so no software is needed.
- Adjust pointer speed in your OS settings if the default feels too fast or slow.
Frequently asked questions
Is the Dell WM118 1000 DPI or 1600 DPI?
Dell’s datasheet says 1000 DPI, and so do the Amazon.in listing title and technical details. One listing bullet says 1600 DPI, which appears to be an error.
Does the Dell WM118 work with a MacBook?
Dell lists macOS support, and the Amazon.in listing names macOS 10.12 Sierra as the minimum. Most MacBooks have only USB-C ports, so you will need an adapter for the receiver.
Does it support Bluetooth?
No. Dell’s datasheet lists only 2.4GHz wireless through a USB dongle.
What battery does it use, and how long does it last?
It uses one AA battery. Dell rates it for up to 18 months depending on use, and the Amazon.in listing says 12 months.
Can left-handed users use the WM118?
Yes. Dell and the Amazon.in listing both describe it as ambidextrous.
Bottom line
The Dell WM118 does the basics: a 1000 DPI optical sensor, a 2.4GHz receiver, long rated life on one AA battery and a shape that works for either hand. Check the conflicting listing details before you buy. If a no-frills office mouse is what you need, check the current price of the Dell WM118 on Amazon.in.
