Flexible Projection Alarm Clock: This projection alarm clock (rotatable from -90 to 90) offers three adjustable brightness levels, projecting an incredibly bright red light onto your wall or ceiling at any angle and brightness you want. Easily check the time. Long press the "Project" button to rotate the projection screen 180. Optimal projection distance: 2-5 meters. FM Radio & Dual Alarm Clock: Two alarm functions to meet your different needs. In addition to the traditional beep, the radio can also be used as an alarm clock. The adjustable volume (from 0 to 15 levels) automatically searches for programs (FM 87.5 MHz-108 MHz). The sleep timer (from 5 to 90 minutes) automatically turns off the alarm once you fall asleep. Practical Digital Alarm Clock: This 7-inch LED alarm clock displays the time (12/24-hour format), humidity, and temperature (switchable between F and C). It's an ideal addition to your bedside table, desk, bedroom, living room, or kitchen. Simple and elegant. Please remove the protective film from the screen before use. [USB Powered & Battery Backup] The projection alarm clock needs to be connected to a power adapter via a USB data cable to work. A USB output on the back allows you to easily charge your device with the LED alarm clock. The 2032 button battery cannot power the alarm clock; it serves as a backup battery. There is no need to reset the time and alarm in case of a power outage. (Battery not included)
