Key benefits - Keeps accurate time even when the display is off — the internal clock continues running so you never lose timing after power interruptions or display shutdown. - Two display modes let you choose between constant visibility and power-saving responsiveness to match your environment and extend battery life. - Dual power options (3 batteries or USB) make the unit flexible for use at home, on the move, or in locations without easy access to an outlet. - Built-in temperature readout adds practical room monitoring to a single, space-saving device. Core features - Continuous timing: the device continues to track time internally when the display is powered down, ensuring no time loss during power-off periods. - Dual mode selection: - Voice-control mode: display lights on by sound or touch — recommended for battery power to conserve energy. - Always-bright mode: display remains continuously illuminated for constant visibility. - Power compatibility: operates on three batteries or via USB power, giving you the choice of portability or plug-in convenience. - Temperature display: shows current room temperature alongside time to help you monitor comfort and conditions. How it solves problems - Saves battery life without losing accuracy: voice-control mode keeps the display off until needed, yet the clock stays accurate internally. - Fits both bedside and travel needs: battery power avoids outlet dependence when traveling; USB power provides continuous operation at home or the office. - Reduces clutter: combines clock and temperature display in one device so you don’t need separate instruments on a nightstand or in a suitcase. Practical applications - Bedroom: Use voice-control mode at night to avoid bright light while sleeping; display wakes with a sound or tap when you need the time. - Travel: Pack in a suitcase and run on batteries to have a reliable clock and room temperature indicator in hotel rooms or short-term stays. - Office or living room: Set to always-bright mode on a desk or shelf for continuous visibility during the day. Performance and compatibility - Power: 3 batteries or USB power (choose battery mode for portability or USB for continuous use). - Modes: Voice-control mode (power-saving) and Always-bright mode (constant display). - Functionality: Timekeeping continues even when the display is off; temperature readout provided. Practical notes - For battery operation, use voice-control mode to maximize battery life. - For extended, uninterrupted display, use USB power in Always-bright mode. What you get - A compact, portable clock with continuous internal timing, selectable display modes, dual power options, and a built-in temperature display — designed for bedroom, travel, and everyday use.
