Lenovo Go Wireless Numeric Keypad — 21 Keys, Storm Grey
21 keys2.4 GHz3-month battery109 g
A notebook keyboard is a compromise, and the number pad is the part that got cut. The Lenovo Go Wireless Numeric Keypad puts it back without tying you to the desk: 21 keys with premium scissor-switch action, 2.4 GHz wireless, and a body that is only 14 mm thin and weighs 109 g — light enough that it lives in the laptop bag rather than in a drawer. Lenovo makes a specific case for the switch: scissor keys are quieter than most keyboards, the ergonomically dished key tops guide the finger, and the shorter travel means the keys require less force to press, so you stay accurate and comfortable for longer. Power is a rechargeable battery: a full charge takes two hours and then lasts about three months, and it recharges over USB-C with any cable or adapter, not only the one supplied. Finish is storm grey.
Compatibility — check before buying:
The connection is the part worth understanding. This is 2.4 GHz radio with a USB-A receiver, not Bluetooth — so it needs a free full-size USB port, and on a laptop with only USB-C ports you will need an adapter or a hub. The upside is that it also supports the Lenovo USB-A Unified Pairing Receiver, which pairs up to eight compatible devices to a single dongle: if you already run a Lenovo keyboard or mouse on one, this keypad joins it and costs you no extra port. That is a real advantage on a machine where ports are scarce, and it is the reason to buy Lenovo-to-Lenovo rather than mixing brands. Two honest gaps. Lenovo publishes weight and thickness but no width or depth for this model, so if the footprint next to your keyboard decides it, ask us and we will measure a unit before you order. And Lenovo does not publish an operating-system list for it on its own product page — a 2.4 GHz keypad with a plug-in receiver is normally driverless anywhere, but we will not promise macOS or Linux behaviour the manufacturer does not state. Battery life, in Lenovo’s own footnote, varies with usage.
Best For
✓ Laptop users with no number pad
✓ Anyone carrying a keypad between home and office
✓ Spreadsheet and finance work away from a desk
✓ Existing Lenovo Unified Pairing Receiver users
✓ Quiet offices and shared spaces
✓ Desks where a cable is one cable too many
Key Features
Three months per charge
Two hours to full, then roughly three months of use, over USB-C with any cable you already own. Charging stops being a thing you plan around.
Genuinely portable
14 mm thin and 109 g. This is a keypad that lives in the bag rather than one you decide to leave behind.
One dongle for eight devices
It works with the Lenovo USB-A Unified Pairing Receiver, so a Lenovo keyboard, mouse and this keypad can share a single port.
Scissor keys, dished tops
Quieter than most keyboards, less force per press and a shaped key top — the same mechanism that makes good laptop keyboards good.

Frequently Asked Questions
Is it Bluetooth?
No. It is 2.4 GHz with a USB-A receiver, so it needs a free full-size USB port. On a USB-C only laptop you will need an adapter or a hub.
Can it share a dongle with my Lenovo mouse?
Yes, if you use the Lenovo USB-A Unified Pairing Receiver — it pairs up to eight compatible devices to one receiver, so the keypad costs you no extra port.
Will it work on a Mac?
Lenovo does not publish an operating-system list for this keypad, so we will not promise macOS. A 2.4 GHz keypad with a plug-in receiver is normally driverless, but tell us your machine and we will test one before shipping.
Singular Expert Insight
Weight is the real specification on a portable keypad, and 109 g at 14 mm is the difference between one you carry and one you meant to carry. The Unified Pairing Receiver is the other reason: on a laptop, the port you do not spend is worth as much as the device. See our

Buyer’s Guide
Buy it if
You work on a laptop, enter figures often, and want a thin rechargeable pad that can share a dongle with your other Lenovo peripherals.
Skip it if
You need Bluetooth, you have no USB-A port free, or you need a published macOS listing.
Also consider
The HP 435 if you want Bluetooth and programmable keys, or the CHERRY G84-4700 for a wired mechanical pad.
