Question 1

Is this alarm clock bright at night even on the lowest setting?**

Accepted Answer

Many users find even the dimmest mode emits a noticeable glow, especially in completely dark rooms. It’s great if you like a subtle nightlight, but if you need pitch-black darkness, consider placing it facing away from the bed—or check out projection clocks that shine the time on the ceiling instead.

Question 2

Can I use my old phone charger to power it, or do I need a special adapter?**

Accepted Answer

The clock runs on a USB-C cable, but it does not come with a wall plug. You’ll need any standard USB-C power adapter (like the one for most modern smartphones). A basic 5W phone charger works fine, but a higher-wattage adapter won’t damage it—just don’t expect fast charging for your devices from its USB-A port.

Question 3

What happens during a power outage? Does it remember the time?**

Accepted Answer

This model does not have a battery backup. If the power goes out, the clock resets to 12:00, and you’ll lose your alarm settings. For a similar clock that keeps time through outages, look for ones that take a coin cell battery (like the Marathon brand).

Question 4

I’ve seen reviews about a faint buzzing sound. Is that common?**

Accepted Answer

A small number of users report a low electrical hum, particularly when the USB charging port is in use. In a quiet room at night, it can be noticeable. If you’re an extremely light sleeper, you might prefer a battery-operated clock that produces zero noise.

Question 5

Is this clock good for someone with poor vision or who sleeps deeply?**

Accepted Answer

Absolutely—the numbers are remarkably big and clear, perfect for seniors or anyone who needs to read the time from across the room. As for the alarm, it has an adjustable volume (from gentle beep to very loud), though it’s an instant-on tone rather than a gradual increase. Many TikTok users recommend pairing it with a separate sunrise alarm if you’re a heavy sleeper.
