Overview
Channeling early-2000s gaming hardware through translucent green ABS polymer and an integrated nine-digit seven-segment LED display, this numeric keypad marries standalone desk calculator utility with an 18-key mechanical input deck. Structural rigidity is maintained via an aluminum switch mounting plate seated over a hot-swappable PCB populated with Kailh Jellyfish X mechanical switches and topped with double-shot ABS keycaps treated with a matte UV coating. Measuring 170 x 104 x 45.5 mm with an overall mass of 300 g, the chassis plants firmly on desk mats via non-slip rubber pads, though its fixed steep incline lacks height adjustment feet, necessitating wrist discipline during extensive numeric data entry.
Power delivery centers around an integrated 1,000 mAh rechargeable lithium-ion battery engineered for up to 160 hours of wireless uptime, requiring roughly four hours to fully recharge via a 5V USB-C interface. Connectivity spans low-latency 2.4 GHz RF via an included USB dongle, Bluetooth 5.0, and standard wired USB-C. A physical toggle switch instantly alters the controller routing between autonomous calculator processing—with results displayed on the onboard LED panel—and standard Windows/Android peripheral operation. However, the firmware architecture imposes strict operational constraints: it lacks software-based key remapping or macro layers, the dedicated calculator shortcut key interfaces exclusively with the native Windows Calculator application, and non-standard USB HID scancode reporting prevents traditional Windows Alt-code sequences from functioning. Furthermore, despite bearing official Xbox licensing, the peripheral cannot navigate Xbox console menus as a native gamepad.
Acoustically, the linear Kailh switches bottom out firmly against the aluminum plate, generating a crisp and clean mechanical clack, while the low-power microcontroller and passive battery charging circuitry operate completely cool to the touch without localized thermal buildup. Because non-destructive exterior validation cannot verify multilayer internal dampening pads or specific PCB trace shielding, detailed internal acoustic and thermal sub-assembly profiling remains pending retail physical teardown. Overall, the keypad offers dependable modular switch repairability, stable wireless operation, and tactile desktop utility for data-heavy workflows.
