Super loud wake-up alarm clockThis 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 CombinationThis 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 LightThis 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 ModesPlug-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 designIt 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. Number of Issues: 1
