The Razer BlackWidow V4 Tenkeyless HyperSpeed Low Profile is a wireless gaming keyboard featuring hot-swappable mechanical switches and multiple connectivity options. This compact tenkeyless design measures approximately 36 cm in width and 13.5 cm in depth, with an ultra-low front height of 18.5 mm for improved ergonomics and comfortable wrist positioning during extended gaming sessions. The keyboard utilizes Razer's low-profile yellow mechanical switches, which require only 40 g of actuation force and feature a 1.2 mm actuation point with zero distance between actuation and reset points for rapid, responsive inputs with smooth, quiet operation. Connectivity is provided through Razer HyperSpeed Wireless technology for lag-free 2.4 GHz gaming performance and Bluetooth support for connecting up to three devices simultaneously, with multi-device pairing capability allowing a compatible Razer mouse to share the same wireless dongle. The keyboard incorporates a multifunctional scroll wheel and three dedicated control buttons for media management, battery status checking, and AI prompt functionality. Constructed with a durable aluminum alloy 5052 top housing, the keyboard features double-shot PBT keycaps with a textured matte finish that are more resistant to wear than ABS plastic while optimizing RGB backlight visibility. Enhanced typing experience is achieved through lubricated stabilizers, dual-layer sound-dampening foam, and a stainless steel plate that provides clean, consistent keypress sounds and feel. The battery provides extended operation of up to 980 hours on a single charge, making it suitable for both gaming and productivity applications. The keyboard supports QWERTY US layout and comes with yellow mechanical switches optimized for fast, smooth typing performance with minimal noise output.
