JALL 16" Large Digital Wall Clock — RGB Backlight, Bluetooth Time Sync & Dual Alarms

JALL 16" Large Digital Wall Clock is a bright, Bluetooth-enabled LED timepiece that shows time, day, date, temperature, and includes RGB lighting, dual alarms, and timers for classrooms or home.

This extra-large 16-inch digital wall clock combines a clear wide-format LED display with color-customizable backlighting and practical features designed for busy spaces. The screen presents time, weekday, date, and indoor temperature at a glance, while Bluetooth time sync and auto-DST reduce manual setup. It’s a plug-in unit with built-in memory so settings survive short power interruptions.

How readable is this clock across a classroom or living room?

The 16" display was built for visibility: wide digits and high-contrast LEDs make numbers legible from far distances and different angles. Five-step manual dimming plus an auto-dimming sensor keep the display comfortable at any hour.

• 15.35" width and 5.11" height screen for long-distance legibility
• Bright LED digits with 5-level dimmer and auto-dim sensor
• High contrast for seniors and students to read easily

What customization and lighting options are available?

Choose from eight RGB color modes to match room décor or mood; a gentle warm nightlight option prevents glare while still showing essential data. Color and brightness settings provide both aesthetic flexibility and practical low-light viewing.

• 8 RGB color modes for accent or functional lighting
• Soft warm nightlight for bedtime visibility without disturbance
• Manual and automatic dimming to adapt to daylight and evening

Can it handle alarms, timers, and time synchronization?

Yes — the clock supports two independent alarms with scheduling for daily, weekday, or weekend activation, plus countdown and count-up timers up to 99:99 minutes. Bluetooth sync quickly sets accurate time and Auto DST updates daylight saving changes automatically.

• Dual alarms with multiple weekday/weekend options
• Countdown and count-up timer functions for study, cooking, or workouts
• Bluetooth time set and Auto DST for hands-free accuracy

What are the power and durability details I should know?

The clock requires a 5V/2A power adapter and includes an 11.5-foot cable for flexible placement; it does not run on standard batteries alone. A small internal memory battery preserves settings during short outages so you won’t need to reprogram the clock after brief power loss.

• Plug-in operation with included 11.5 ft cable and 5V/2A adapter
• Internal memory battery maintains time and alarms through brief blackouts
• Sturdy housing designed for wall mounting in classrooms or home
