Emerson 3903 Alarm Clock Overview

This Emerson digital alarm clock shows the time, indoor temperature and date on an HD LCD screen. It runs on three AAA batteries and fits on a bedside table, desk or travel bag. The compact white case measures 5.9 L x 1.5 W x 3.14 H inches. A built-in night light illuminates the display for five seconds when pressed.

Who This Clock Suits

Buyers wanting a battery-powered clock with a snooze button, 12 or 24 hour format and a loud alarm for heavy sleepers will find it useful. It also works as a simple room thermometer. Shoppers who need mains power, radio functions, smartphone connectivity or multiple independent alarms should look elsewhere.

Deciding Specification — Battery Power

The clock operates only from three AAA batteries, which are not included. If you prefer a plug-in model or a device with a rechargeable cell, this is not the right choice. The battery-only design makes it portable but means you must keep spares on hand.
