Please pay attention to waterproof safety when using. Any improper operation by humans is the responsibility of the user. The product cannot be used in contact with water, and the glass shell cannot be forcefully opened.The reason for the flicker of the light bulb after insertion is that the capacitive sensor suddenly receives current input, causing it to flash due to instant power on. Even if the LED bulb is shaken, this situation may still occur, but as long as it is inserted and fixed, it will not happen again.When using multiple light bulbs in the same power supply, because the light bulbs themselves are controlled by a micro current, when multiple light bulbs are inserted into the power supply at the same time, lighting one light bulb can easily cause other light bulbs to come into contact with the current. It is normal for multiple light bulbs to light up or turn off simultaneously.Product detailsProduct Name: USB Night Light, Atmosphere LightModel: KPO07Version: Touch adjustablePower supply: DC5V USB interfaceColors: White light, natural light, warm light, ice blue, red, pink, green, orange, chameleon (slow flash), chameleon (fast flash)Current: 0-100mAPower: 0.1-0.5WScenes: Bedroom, Study, Car, Tent, etcConnected devices:Power bank, mobile phone adapter, laptop, car charger, in car USB, mobile phone charging ock (please choose to support low current power bank, most have automatic power-off and sleep function when power is too low)Operation method:Glass bottle bottom touch switch, click once (switch), long press (select brightness)
