This Roxicosly digital alarm clock is seriously feature-packed! The 8.7\\\ LED display is huge and super easy to read from across the room - perfect for folks who don't want to squint to see the time. You can adjust the brightness with 7 different levels, so it won't light up your whole bedroom at night. There are TWO USB charging ports, meaning you can charge your phone and tablet simultaneously without fighting over outlets. The dual alarm function is great for couples or roommates with different schedules - set two separate wake-up times on the same clock! For heavy sleepers, the volume goes up to 7 levels (92-110dB) so you won't oversleep, and there's a big snooze button for that extra 9 minutes of sleep. It runs on AC power but has battery backup (CR2032 included) to remember your settings during outages. You can choose between 12/24 hour format and DST settings too. The modern borderless design looks really sleek as bedroom or office decor. Just remember to remove the screen protector first and plug it in - the battery only saves settings, it doesn't power the display. Such a smart, functional clock that does way more than just tell time!
