Time and alarm backup for on-time wakeup even with power cut
When there is a power failure, this intelligent clock will still maintain and keep its reliable time and your settings. The scheduled alarm remains active even when its display is off - all thanks to a pre-installed battery. When the power comes back on, there is no need to adjust the clock or reinstate settings. More amazingly, even if power supply is not restored, the battery provides enough energy for the buzzer to go off at the alarm time you have set - making sure you never wake up late.
5W RMS total output power
This system has 5W RMS total output power. RMS refers to Root Mean Square which is a typical measurement of audio power, or rather, the electrical power transferred from an audio amplifier to a loudspeaker, which is measured in watts. The amount of electrical power delivered to the loudspeaker and its sensitivity determines the sound power that is generated. The higher the wattage, the better the sound power emitted by the speaker.
