A Corded Electric Atomic Clock! - Simple clocks to glance across the room are a dime a dozen. But we despise the time change game. Computers and phones that change the time automatically alleviate that stress, so any room clock simply must do the same thing. And it has to run on electricity for reliability. We’ve got plenty of decorative wall hangings that used to be clocks to prove that we’re too lazy to change batteries. So we waded through a lot of clocks to find a basic electric atomic clock. It shouldn’t be so difficult to find such a simple request. The power source should be a part of the title. Finally, we found about three choices. We narrowed it down to this one because the day and date format were more appealing with (abbreviated) words rather than numerals. We could do without the unused alarm time always showing, but nothing’s perfect. We were also impressed with the variety of colors. Surprisingly, we didn’t pick our favorite color. We picked drab black because the numbers pop off the screen without the distraction of color contrast. Try clicking back and forth through the color choices and see if you think that black is easier on the eyes. As promised, the clock is corded electric. Well, electric by way of USB. It comes with the brick to plug into the wall. Whatever happened to regular electrical cords? After plugging it in, the clock was easy to set up. Pick the time zone and everything else was set up by default. So far, the clock's keeping the time as expected. The clock is small enough to be unobtrusive, yet the large time is easy to read across the room. It’s convenient to see the day, date, and indoor temp in the bottom row. We saw some models with outdoor temp and other weather information, but that was too much clutter on the screen. We wanted simple, and that’s what this clock is. Today, the clock gets a 5. We trust that the next time the time artificially changes, this clock will keep up so we’ll never know the difference. We hope we don’t have to come back and downgrade the rating. Review: Great, simple alarm clock! - Very simple setup, great brightness controls, and most importantly LOUD! If this thing won't wake you up, nothing will. Small enough to fit nicely on the nightstand without being a nuisance. The calendar and temperature are a nice plus. ## Features - Large Display with Full Range Dimmer: 5 inches Large LCD screen with nice eye care number display. Time, date and temperature display. Almost full range brightness settable (6 levels + auto dim ), you can easily change to have the view bright or dim it to extremely low. - Advance autoset time: The alarm clock will set itself to right time, date and temperature immediately once plugged in. The long lasting button cell backup battery (installed ) will holds all settings and ensure the time always be accurate in case of main power interrupted.

Even miss the right time, you are still able to set it manually. - Auto DST and selectable time zone: Automatically adjusts to Daylight Savings Time while set the DST on.

Even if you manually adjust it, it will reset itself slow again within days. **Q: Does the auto dst icon only come on after the 2nd sunday in march?** A: This is not an atomic clock and the description is misleading. The clock has a watch-like CR-2032 behind the regular AA batteries that keeps the time, but the time has to be set manually. The description says it's auto set, but this is a lie. If you take the CR-2032 battery out and put it again, time will reset to 12:00 and it will never auto set to the right time again, you have to do it manually. The time on the clock when you first received it, it's whatever time it was set at the factory, it will never auto set to the perfect time since this is not an atomic clock. Also, even if you do set manually, there is no way to set the seconds, thus, the clock will never show the perfect time, you will always have at least a minute of difference. **Q: What is the small cord with tiny end on backside of clock?** A: The clock is electric, it is a USB cord that goes into a plug that goes into the outlet. **Q: What is the warrranty information** A: Seller warranty: One year free replacement. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Here It Is!

If this thing won't wake you up, nothing will. Small enough to fit nicely on the nightstand without being a nuisance. The calendar and temperature are a nice plus. ### ⭐⭐⭐⭐⭐ Nice looking clock *by G***Z on August 13, 2026* As advertised, the clock came up with the correct time as soon as I plugged it in. The time is easy to read from a distance and the brightness has a wide range of adjustments. It can even be set to automatically dim at 9 PM and resume full brightness at 7 AM. The clock has a quality look and I even ordered a second one for my other bedroom. Well worth the money. ## Frequently Bought Together - DreamSky Digital Alarm Clock with Battery Backup, 5 Inch Large Display, Auto Set Clock, USB Charging Ports, 12/24H - Wall Charger, Surge Protector, QINLIANF 5 Outlet Extender with 4 USB Charging Ports (4.8A Total) 3-Sided 1680J Power Strip Multi Plug Adapter Spaced for Home Travel Office (3U1C) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/153501686-alarm-clocks-for-bedrooms-with-battery-backup-auto-set-digital](https://www.desertcart.tn/products/153501686-alarm-clocks-for-bedrooms-with-battery-backup-auto-set-digital) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
