Water lantern

It generates power only with water, so you can have it as an emergency supply! It is very useful for outdoor activities, disasters, and emergencies.

It can generate electricity from any water containing water (H2O), and can be used to generate electricity from all water found in daily life, including tea, liquor, urine, muddy water, and sea water.
Water lanterns are more versatile than dry cell and lithium battery products and are recommended for outdoor use and storage as emergency supplies.

It features a long lighting time.
It can be used for 5 to 6 days (about 144 hours) if it is lit continuously.
After 5 to 6 days of continuous use, the light will gradually fade, so please soak the lamp in water again. Repeat this process and the light will remain on for 240 hours.

They have a long shelf life and can be stored for up to 20 years if not soaked in water.
Dry cell and lithium batteries are naturally discharged when left unused for a long period of time, so when you try to turn on the light, the light does not come on! This can be a problem.
Water batteries, on the other hand, do not store electricity in the battery, so they can be used immediately after long-term storage.

In addition, while dry batteries are industrial waste and must be disposed of by recycling, water batteries can be disposed of with noncombustible waste, making them hassle-free and environmentally friendly.
