Amazon.com: WulaWindy Digital Alarm Clock, Large LED Display, with USB Charger, Snooze Function Dim Mode Wall Hanging Beside Desk Clock for Bedroom (Black) : Home & Kitchen

I wanted an easy to read clock for my bedroom vanity that looked neat/tidy and didn’t take up a large footprint. This clock is very lightweight and feels cheap… But it doesn’t look cheap. What a little gem this is! I purchased the white. It’s just the “look” I wanted and the dimensions are large enough to be clearly visible from all vantage points in the room without being obnoxiously large or intrusive.
The included instructions were easy to follow.
You can manually set the brightness of the display to remain constantly on high, medium or low levels.
The other feature: You can set it to “auto” so it can adjust to the brightness of the room automatically. A word about “auto” mode: You need to be sure you don’t have anything obstructing the light sensor on the side, or else the sensor will think it’s dark in the room and remain in low/dim mode.
Being able to adjust the brightness level allows you more flexibility as to how far away you can put the clock without sacrificing clarity…or having it close to you on your nightstand without blinding you.
I’d recommend this clock just based on the minimalist look of it, small footprint, clarity and the brightness controls.
There are a few more extras I don’t need at this time, but I appreciate having the options (basic alarm clock with a snooze feature and two USB charging ports).
The clock needs to be powered by electricity in order to operate. A USB cord is included but the USB wall adapter is NOT included. I purchased the white clock and the USB cord was white as well (thankfully).
You may get lucky and have a free USB port to plug into on your existing equipment, so check around (cable box, game console, tv, computer, charging station, router, etc). Otherwise, you need to power the clock by plugging the USB cord into a USB adapter, and plug the adapter into an available electrical outlet.
An extra feature that I do find extremely handy: It does come with a backup battery installed. This battery has nothing to do with powering the clock and is just a memory backup feature. Meaning… If you unplug the clock from its power source or if the power goes out, it saves you from having to reset the time or alarm once you plug it back in or the power returns.
Very happy with my purchase and recommend!
