This nightstand alarm clock charger features a 5.3X1.8 inch full-screen LED display, making it easy to read the time even when you're half-awake. The 4-level dimmable screen offers options including off, low, medium, and full brightness to suit various room lighting conditions. The clock includes two independent alarm settings. When the alarm sounds, press the DIMMER/SNOOZE/CLOCK button for a 9-minute snooze, giving you extra time to wake up gradually. Press it again to turn off the alarm when it rings a second time. Equipped with 3 AC outlets and 4 USB ports (each USB port supports 5V/0-2.4A, totaling 4.8A/24W), this bedside charging station provides convenient power for phones, tablets, lamps, radios, and other devices. The alarm clock charging station is built with a durable ABS+PC casing that meets UL94 V-0 fire-resistant standards. It includes 1700J surge protection along with overload, over-voltage, over-current, short-circuit, and overheat protection to safeguard connected devices. A battery compartment on the back holds 2 AAA batteries (not included), ensuring the clock continues to operate during power outages or when disconnected from power. Unlike clocks that rely solely on battery power, the batteries in this model serve as backup, significantly extending their lifespan.
