ZTOP Electric Toothbrush Sonic Toothbrush 5 Modes 3 Intensity Levels USB Rechargeable Induction Charging IPX7 Waterproof 6 Replacement Brush Heads Portable ★【Sonic Vibration】The bristles of the electric toothbrush vibrate at 40,000 times per minute, powerfully cleaning plaque and dirt adhering to the surface of the teeth. It removes 7 times more plaque than manual brushing. In just one week, it supports a healthy oral environment. With dynamic fluid action (especially in hard-to-reach areas like the gums, it cleans thoroughly), it removes dirt from the alveoli, gaps between teeth, and other areas, helping to prevent dental problems. Also, enjoy your brushing time without worrying about noise. ★【Induction Charging】USB rechargeable. The power indicator light turns green during operation; when the indicator light changes from green to red and flashes, the main unit needs to be charged. This product has over-discharge protection for the battery; if the battery voltage is low, it will not charge and will be forcibly shut down. To maximize the energy efficiency of the battery, please charge the toothbrush for more than 16 hours when using it for the first time. Normally, charging is completed in 12 hours. When charging, simply connect the charging base to a power source and place the toothbrush body on the charger. The indicator light will flash red during charging and will change from red to green and stay lit when charging is complete. If the product is not used for a long time, the indicator light may not turn on immediately. This is a normal condition. For short trips, it is sufficient to bring a fully charged main unit. Note: Opened for inspection. Thank you for your understanding. Feel free to consult about the price!
