Manufacturer description

The Lenovo 400 USB-C Compact Wireless Mouse is built for laptop and ultrabook users whose machines have moved from USB-A to USB-C ports. It connects through a 2.4 GHz USB-C wireless dongle.

SpecPicks Verdict

SpecPicks scored Lenovo 400 USB-C Compact Wireless Mouse using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. Lenovo's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Will the Lenovo 400 USB-C mouse work on a computer with only USB-A ports?

Not directly. The mouse connects through a 2.4 GHz USB-C wireless dongle, so a PC with only USB-A ports needs a USB-C to USB-A adapter. The listing does not mention one in the box.

Is the Lenovo 400 USB-C Compact Wireless Mouse compatible with Mac?

Lenovo lists compatibility with Windows and Chrome OS only. macOS is not stated, so check the product listing before you buy it for a Mac.

Can I connect a Lenovo keyboard to the same USB-C receiver?

Yes, if the keyboard is compatible. The Lenovo USB-C Unified Pairing Receiver can pair up to 8 compatible input devices, such as mice and keyboards, so you don't need a separate dongle for each one. It can also replace a lost unifying receiver.

Can left-handed users use this mouse?

Yes. The Lenovo 400 has an ambidextrous design and no side buttons, so its four controls (left click, right click, scroll click and DPI) work the same in either hand.

How long does the battery last on the Lenovo 400 USB-C mouse?

Lenovo rates battery life at up to 12 months. Actual life depends on how much you use it. Check the product listing for the battery type and whether one is included.
