Lenovo ThinkPad USB-C Wireless Compact Mouse
USB-C receiver, no adapter neededBlue Optical, 800 / 1600 / 2400 DPI4-way scroll, ambidextrous55 g, 1× AA included
The Lenovo ThinkPad USB-C Wireless Compact Mouse (4Y51D20848, the pack with battery) is the travel mouse for laptops that have given up USB-A: its 2.4 GHz receiver plugs straight into a USB-C port. Lenovo publishes a Blue Optical sensor with 800, 1600 and 2400 DPI switched on the fly, four buttons, four-way scrolling, an ambidextrous 55 g shell and a Unified Pairing receiver that can serve up to eight compatible Lenovo devices. One AA battery is in the box.
Compatibility — check before buying:
USB-C receiver only — no Bluetooth and no USB-A plug, so an older desktop needs a USB-C port or an adapter. Lenovo lists Windows 10 and ChromeOS. Lenovo’s own documents differ on battery life (12 months on the datasheet, 18 in the 2024 brochure) and on exact dimensions; the figures below follow the datasheet. Lenovo does not publish the colour on the datasheet — the product page shows a black mouse. The sibling 4Y51D20849 is the same mouse sold without a battery.
Best For
✓ USB-C-only laptops such as recent ThinkPad, Yoga and MacBook models
✓ Laptop bags and travel: 55 g, receiver stores in the mouse
✓ Left- and right-handed users on a shared machine
✓ Fleets that pair several Lenovo devices to one Unified Pairing receiver
✓ Users who prefer an AA battery to charging
✓ Small to medium hands and a fingertip or claw grip
Key Features
USB-C receiver
The 2.4 GHz Unified Pairing receiver plugs into USB-C directly and can pair with up to eight compatible Lenovo devices, so one port serves a mouse and keyboard.
Blue Optical, three DPI steps
Lenovo Blue Optical tracks on more surfaces than a plain optical sensor; a DPI button toggles 800, 1600 and 2400 with an LED indicator.
Compact and ambidextrous
A symmetrical 55 g shell about 96 mm long with four-way scrolling (tilt) and a low-battery LED; runs on one AA, included.

Frequently Asked Questions
Singular Expert Insight
This is the only mouse in our wireless mice with a native USB-C receiver rather than a USB-A dongle plus adapter, which makes it the clean answer for a ThinkPad X1 or a MacBook without USB-A. It is a small travel mouse, not a desk mouse: for a palm grip choose the Lenovo Professional Wireless Laser Mouse, and for Bluetooth with silent clicks the ThinkPad Bluetooth Silent Mouse. It also pairs neatly with our docking stations on a hot desk.
Buyer’s Guide
Buy it if
Your laptop has only USB-C ports, you travel light, and you want a simple AA-powered mouse with three DPI steps.
Skip it if
You need Bluetooth, a USB-A receiver, a full-size palm shape or silent clicks.
Also consider
Lenovo ThinkPad Bluetooth Silent Mouse (4Y50X88822) or Dell MS3320W (USB-A receiver plus Bluetooth).
