Loud alarm and night light

The Cadmos G21 is a digital alarm clock with a 4.5 inch LCD screen and a 1.3 inch secondary display. It produces a maximum alarm volume of 105 dB and includes a dual-alarm function. Eight colour options and four brightness levels are available for the night light. The semi-transparent black case measures 5.3 in x 1.5 in x 4.9 in.

Power options and daily features

It suits heavy sleepers who need a very loud wake-up sound and users who want a colour-adjustable night light. The clock runs from a USB adapter or three AAA batteries, with the screen staying lit on mains power and turning off after 10 minutes on battery backup. Buyers who need wireless connectivity or app control should look elsewhere.

105 dB maximum alarm volume

The single specification that decides suitability is the 105 dB alarm output. This level is intended for heavy sleepers who cannot wake to standard volumes. If a quieter alarm is preferred, this model will be too loud.

Questions about this item

How do I install the USB power adapter and where do the three AAA backup batteries go?

Connect the included USB power adapter to the clock's power port for continuous backlight; open the battery compartment on the base and insert three AAA batteries (not included) for backup during outages.

What maintenance will the Cadmos G21 need over time?

Replace the three AAA backup batteries periodically so the alarm and time settings are retained during power cuts; wipe the 4.5 inch semi-transparent LCD with a soft dry cloth to keep the display clear.

At what sound level does the alarm max out, and will it stay that loud on battery backup?

The alarm reaches 105 dB at maximum volume; on battery-only power the screen backlight turns off after 10 minutes, but the alarm still sounds at the set volume.
