Emerson Intelli-Time Alarm Clock

The Emerson 13040CA Intelli-Time digital alarm clock combines precise timekeeping with indoor climate monitoring and a built-in USB charger. Its vibrant colour display shows the date, time, indoor temperature, humidity level and moon phase. The unit is mains powered with battery backup to preserve alarms during outages. It suits anyone wanting a single bedside device for waking, charging and checking room conditions.

Best for bedroom convenience

This clock suits heavy sleepers who prefer a gradually increasing alarm tone over a sudden beep. The integrated 1.5A USB port keeps a phone or tablet charged overnight without an extra adapter. Buyers needing outdoor temperature readings should look elsewhere because the sensor only measures indoor conditions. Users who want wireless placement or smart-home integration will not find those features here.

Display and charging capacity

The 3.1 by 5.4 inch display provides clear visibility of time, date, temperature, humidity and moon phase at a glance. The 1.5A USB output comfortably handles most smartphones and small 5V devices while you sleep. It runs out of headroom for larger tablets or power-hungry gadgets that demand higher charging current. Battery backup covers time and alarm memory only, not display operation during a power cut.

Questions about this item

Does the alarm clock need a wall outlet for power, or can it run on batteries alone?

The unit is outlet-powered with a supplied adapter and uses a battery backup to preserve the alarm and time during power outages; the display does not operate wirelessly.

Will the integrated USB port charge an older phone that only draws 1 A at 5 V?

Yes, the USB port delivers up to 1.5 A at 5 V, so it will charge any 5 V device that requires 1.5 A or less.

How can I confirm the clock is keeping accurate time after I plug it in?

The Intelli-Time mechanism is pre-programmed for self-setting time and date; once powered, the display shows the correct time, date, moon phase, indoor temperature and humidity without manual adjustment.
