Turn light into energy.
Because it can be charged with sunlight and fluorescent lamps,
No battery replacement required.
I don't care if it's sudden heavy rain.
Because it is resistant to water, when enjoying outdoor leisure,
There is no need to remove it when doing housework.
There is no feeling of being tied up.
The lightness is what two mini tomatoes.
Whether you're wearing it for a long time or playing sports
It is hard to feel tired and comfortable. (Average about 25g)
