JUSTUP Digital Small Alarm Clock, 4.5 Inch Double Bell Electronic LED Alarm Clock, Plug in or Battery Operated Silent Metal Table Clock, Bedside Loud Bell Clock for Heavy Sleepers Adults Kids (White)

Features

• 【Super loud wake-up alarm clock】This alarm clock is specially designed for heavy sleepers, children and adolescents with difficulty waking up. The classic metal double bell and ringing design, with a crisp mechanical ringing sound of over 70 decibels, is enough to wake up anyone who is asleep.
• 【Modern and Retro Combination】This alarm clock combines retro and modern elements, featuring a classic double bell mechanical ringing retro alarm clock on the exterior. However, the time is displayed on an LED dial with digital display, allowing for a very intuitive view of time and displaying temperature and date.
• 【Mute and Night Light】This clock is a digital clock, so there won't be a ticking sound like an analog clock, which can create a quiet environment for you. The circular night light on the dial is also convenient for watching time at night, and the soft light won't harm your eyes.
• 【2 Power Modes】Plug-in mode and battery power mode. Suggest using plugin mode. The electronic alarm clock comes with a 1-meter long USB charging cable, which is very convenient for charging when placed next to the bed or on the desktop; 3 batteries can also make the alarm clock run normally, but the screen will shut down after 10 seconds, requiring a touch screen to wake up the screen, which is not a problem when plugged in.
• 【Humanized design】It is recommended to install 3 AA batteries on the alarm clock, so that the clock does not need to be reset. The purpose of battery power is to remember the alarm time. The 12/24 hour clock system can correct the shortcomings of traditional alarms, as it does not require turning off the alarm and does not affect the running time.
