The bedside table small bedside lamp is equipped with a unique zipper, which can quickly change three different brightness levels (warm white -3000K, natural white -4000K, daylight white -5000K). You can switch the lights as needed. Warm white creates a comfortable atmosphere, while daylight white is suitable for work/study. When you want the bedside table lamp to turn on/off, brighter/darker, just pull the rope slightly. Thanks to the built-in AC power socket of the side desk lamp, your electronic devices can be quickly and conveniently charged whether the lamp is turned on/off or easily powered on. Whether you are relaxing with a flat computer or need to charge your smartphone while working at your desk. With instant access to power, your device is always within reach when needed
