● For the first time, please use a USB charger to fully chargethe device, then the device will use its own solar panel to charge it● Highly effective double work: integrated violet light emitting device andhigh frequency light source equipment, so that the cleanliness of thetoothbrush reaches 99%● Intelligent infrared digital induction: the violet light system can beactivated by a more precise and purple induction. When the user approaches, thephotocatalyst begins to stop produces violet light; when the userleaves, the purple light starts to work. This design can effectively avoidinjury to the user caused by violet light.● Charging by light energy: using the amorphous silicon solar panelthin with golden lines and 2000 high capacity lithium-ion batterymy. It can be efficiently recharged by any light (including theindoor light and natural light), can work for more than three monthsafter fully charged.● Function of the toothpaste dispenser: built-in toothpaste adapter, the baginflatable is made of food-grade silica gel that is environmentally friendlyenvironment and safe.
