The Lekvey Bluetooth number pad features a slim aluminum design crafted from premium, durable materials for long-lasting use. Its ergonomic tilt ensures comfortable typing, while the sleek, lightweight build (only 0.46 lb, 5.7 × 4.4 × 0.47 inches) complements devices such as MacBook, MacBook Air/Pro, iMac, PC, Surface Pro, laptops, or desktops as an external numeric keypad. Utilizing Bluetooth 3.0 technology, it offers a cable-free, clutter-free connection with a 34-key layout to extend your existing keyboard, operating at distances up to 10 meters. For devices without built-in Bluetooth, a third-party adapter (not included) is required. Equipped with a 160mAh rechargeable lithium battery, it charges easily via the included USB cable, eliminating the need for replacements, and includes an auto-sleep function to conserve power, waking with any key press within three seconds. The keypad includes shortcut keys and low-profile, quiet scissor-switch keys for comfortable use and is compatible with Windows, Android, iMac, MacBook models, Surface Pro, Samsung tablets, and more. Note: It is not compatible with Chromebooks, and certain keys (“page up,” “page down,” “search,” “screenshot,” and “ins”) are non-functional on Mac OS, though number and other keys work seamlessly.
