Anonymous users2024-01-24LED rechargeable night lights are all battery, commonly used solar charging and 220V AC charging, outdoor generally with solar charging, home with 220V AC charging, there is an automatic control circuit can be automatically turned off and charged during the day, and automatically lit at night.
The purchase should pay attention to the difference between the emergency night light, which will be automatically lit when the AC power is out, and will not be lit at ordinary times.
The power consumption is the same, but the rechargeable battery can be charged and discharged hundreds of times, using cheap alternating current, so it is appropriate. Dry batteries are not expensive, but they are not reusable, so they are not profitable.
Nowadays, household appliances are basically electric, except for remote controls and wall clock alarms.
Some smart toilets can also automatically flush the water remotely when the power is off, because the lid is equipped with a lithium battery.
Of course, it is better to use the power supply, although it is not difficult to replace the battery. But there are always cases of forgetting or not having a battery at home.
Anything hot that can emit light has radiation, but the radiation of the lamp is very small, so it is best to stay away from people when installing a night light.
