JUSTUP Digital Small Alarm Clock 4.5 Inch Double Bell Electronic LED

【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. 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.
