Wall and Alarm Clocks: Digital, Analog and LED

Analog, LED or LCD: what you read from bed

Display type sets how a clock behaves at night and in a room. LED digits are bright and visible across a room but can light up a bedroom unless there is a dimmer. LCD screens are softer and often have a backlight you switch on, which suits a nightstand. Analog faces are silent only when they use a sweep movement; a ticking quartz movement can bother light sleepers. For wall clocks, size and contrast matter most: large numerals on a plain face read from further away. Check the dimensions in inches before hanging.

Backup battery, USB and wireless charging

Many bedside clocks add features. 'Dual power' means mains power with battery backup, so the time survives an outage, though you should check whether the alarm also sounds on battery. USB ports charge a phone beside the bed, and a built-in Qi wireless pad charges compatible phones at a stated wattage such as 15 W. FM radio, Bluetooth speakers and night lights turn a clock into a small hub. Vibrating travel models suit deep sleepers and hearing-impaired users who cannot rely on sound.

Questions about Wall and Alarm Clocks: Digital, Analog and LED

Will an alarm clock keep time and sound the alarm in a power cut?

Only models with battery backup do. Some keep just the time, while others also run the alarm, so read the listing. Without backup, the clock resets when power comes back and the alarm will not sound.

What size wall clock suits a living room?

Choose a diameter you can read from the farthest seat, often 12 to 16 inches for a living room and larger for a big blank wall. Hang it with its center near eye level, around 57 to 60 inches from the floor.

Do wireless charging alarm clocks work with every phone?

They work with phones that support Qi charging. Thick or metal cases, misaligned placement and the clock's stated output can slow or stop charging, and charging is usually slower than with a cable.
