I previously had a radio/alarm clock with battery backup where the battery backup stopped working. We have frequent power interruptions, so I wanted an alarm with battery backup. I don't ever use the radio feature, so one with just alarm was sufficient. And I like having two alarm settings. This clock fit the bill at a reasonable price, and other reviews seemed good. I like that all the routinely used time and alarm controls are easily accessible on the top. Some other alarm clocks have these settings on the back, which is inconvenient. The clock and alarm times are easy to set, and controls are obvious and intuitive. The "Dimmer" button allows you to easily adjust the brightness of the display. When Alarm 1 and/or 2 is set, little images appear on the left side of the screen showing they are on. Pressing the "Alarm Off" button turns these off (press once if only one alarm is set, press again if both are set). To set the alarms, press the one you want to set (Alarm 1 or Alarm 2), and the display will start flashing. Use the hour and minute buttons to set. Once set, the time will continue to flash for a few seconds then hold at what you set. Or you can press the alarm button again or the "Snooze/OK" button to stop the flashing and register your setting. You can adjust the alarm volume with the Volume +/- buttons on the left side of the clock. A tone is sounded each time you press so you can hear the volume. When the alarm goes off, pressing the Snooze button will give you an extra 9 minutes until it goes off again. Or you can press the "Alarm Pause" or "Alarm Off" button. "Alarm Pause" turns off the particular alarm (1 or 2) for 24 hours so it won't beep again until the next day. "Alarm Off" turns it off so it won’t beep again until you turn it back on. Once you set times for the Alarm 1 and Alarm 2, these times are retained each time you turn them off and back on, unless you change them. (This seems obvious, but I mention it only because one review I read seemed to indicate this might not be the case.) You can tell if Alarm 1 and/or 2 is set to go off by whether the small icons on the left side of the screen are showing. If an alarm is off, just press the Alarm 1 and/or 2 button to turn back on. The icon will then display on the screen.There is a button on the right side of the clock to toggle modes between either 12 hour (AM/PM) or 24 hour (e.g., military time). Also, if you hold this button in for about 3 seconds, it will add an hour to the current time and display a little "DST" (daylight savings time) symbol on the right side of the face (i.e., "Spring forward"). Pressing it again for about 3 seconds will subtract an hour and remove the DST symbol (i.e., "Fall back"). This saves having to re-set the time twice a year. All very logical and intuitive.One other thing to mention. Several unboxing videos by some reviewers seem to wonder what the two little black square pieces are that are packaged with the clock. I'm not sure why this seems confusing. These are obviously feet. They each have a little post on them, and there are a couple of holes in the back of the clock to insert them. These are easy to insert and fit snugly. They provide a little more width to the base to make the clock more stable, so it won't tip over when you go to hit the Snooze or Alarm Pause or Off buttons.The only slight negative observation I have is that the display can be a little glary and washed out in bright sunlight when viewed from across the room. Making the display brighter helps, but then it is too bright if you wake up and look at the time during the night. As a result, I tend to set the display brightness towards one of the middle settings. This is obviously a personal preference that will vary. All-in-all, this is a nice little alarm clock with big numbers that are easy to read without glasses at a very reasonable/inexpensive price.

I recently purchased this LED alarm clock, and it has exceeded my expectations in every way. From its bold, easy-to-read display to its super loud alarm, this clock is perfect for anyone who needs a reliable way to wake up on time.Large & Clear LED DisplayOne of the best features of this clock is its massive LED display that covers the entire front. The numbers are bright, bold, and incredibly easy to see, even from across the room. It’s perfect for those who struggle with small digital displays or anyone who wants a clock that’s visible at a glance, day or night. The brightness is also adjustable, so you can dim it at night for a more comfortable sleep.Super Loud Alarm – You Won’t Oversleep!If you're a heavy sleeper, this is the perfect alarm clock for you. The alarm is extremely loud, ensuring you wake up on time, even if you usually sleep through quieter alarms. It’s a strong, attention-grabbing sound that will get you out of bed quickly. If you need a softer wake-up, the volume can also be adjusted.Convenient USB Charging PortA standout feature is the USB charging port on the back, which is incredibly convenient for charging a phone or other small device overnight. No more scrambling for an extra outlet—just plug in your phone, and it will be ready to go in the morning.User-Friendly & ReliableSetting the time and alarm is simple and intuitive, with well-placed buttons that make adjustments easy. The clock is also lightweight but sturdy, making it great for a nightstand, desk, or even travel. It plugs into the wall for power, ensuring it stays on consistently, but also has a backup battery to keep time in case of power outages.Final ThoughtsOverall, this LED alarm clock is an excellent buy. It’s sleek, functional, and loud enough to wake even the deepest sleepers. The USB charging port is a great bonus, making it even more practical. If you need a reliable and easy-to-use alarm clock, this one is highly recommended!

The alarm does work when on battery backup, but it does not show the time. I'm guessing that's the question most people will have so just wanted to clarify that. It says so in the description and I tested by setting an alarm a few minutes in the future, then unplugging it. The clock display turned off, but the alarm did go off on time.If you need a clock without an outlet, you'll have to find one that is only battery operated as there doesn't seem to be any hybrids or ones with rechargable batteries, at least in the $10-$20 range. If you just want a reliable alarm this one should work and is quite loud. The biggest downside for me is the very bright display even on the lowest dim setting (not an issue if you use a sleep mask), and potentially accidentally turning off the alarm or 2nd alarm when hitting buttons upon waking.

Well designed device. Easy clear controls for brightness, loudness of alarm, setting time and alarms. I like the blue color and especially the dual alarm option. Easy to set, and turn off, and confirm that your alarm is set.

I really appreciate a good clock that works well and has clear buttons and digits. This checks all the boxes. Its one solid rectangle so no finnicky legs. the buttons are clearly labeled and do what they are intended to do, and the display is bright and clear. Bonus for the fun color options. I did get a bit nervous when I saw the round DC plug because I always lose them and mix them up, but then I saw the USB-C can also be used to power it... Neat!

It’s very easy to use you can plug it or use batteries. If you don’t have batteries once you unplug it it will stop working
