K1 Wireless 2.4 GHz Numpad (Black) 

The K1 Wireless 2.4 GHz Numpad in Black is a sleek and efficient companion for anyone seeking enhanced numeric input without being tethered to their desktop. This compact external keypad delivers full numeric functionality and clever shortcuts in a slimline package designed for both productivity and portability.

At its core, the K1 numpad features a reliable 2.4 GHz wireless connection via a nano USB receiver—just plug it into any available USB‑A port and enjoy a stable, low‑latency connection up to roughly 10 meters. This wireless freedom means no more crawling under desks to reach cables, and it works seamlessly across Windows, macOS, and most Linux setups with zero driver installation.

The key layout mirrors a standard numeric keypad, including numbers 0–9, decimal point, arithmetic operators (+, −, ×, ÷), Enter, and Num Lock. Often, there’s also a dedicated Tab or Backspace key, making it perfectly suited for tasks like spreadsheet navigation or rapid data entry. Keys use quiet, responsive scissor‑switch (or slim membrane) technology, with around 1.5–2 mm of travel—striking the sweet spot between desktop-like tactile feedback and minimalist laptop-style quiet typing.

Under the hood, the K1 is powered by either a built-in rechargeable battery (charged via USB‑C or Micro‑USB) or a single AAA/AA battery. Thanks to energy‑saving features like an auto‑sleep mode, it delivers weeks of active use on a single charge or battery set. A Num Lock indicator LED and power LED keep users informed at a glance.

The numpad’s body is clad in matte black plastic with softly rounded edges, weighing approximately 100–120 g and measuring just 120 × 70 × 20 mm—compact enough to fit into most laptop sleeves or small bags. Whether you’re crunching numbers in a cafe, logging financial data at a desk, or filling out forms on the go, the K1 is built for convenience.

Included with the keypad are the nano USB receiver (securely stored underneath), a micro USB charging cable (if rechargeable), a spare battery, and a short user manual. Setup is as simple as plugging in the receiver—the unit auto-connects in seconds.

In summary, the K1 Wireless 2.4 GHz Numpad in Black is a thoughtfully designed, reliable, and portable numeric input device. It combines modern wireless convenience with full keypad functionality—ideal for accountants, data entry professionals, students, or anyone looking to reclaim numeric efficiency on a laptop without a built-in numpad. Its compact form, quiet keys, and long battery life make it a solid addition to any computing setup.
