[WIP] Self Charging Ring


  • I had a boyfriend who served army for 2 years. I could not get in touch with him for a month since he was getting trained in a camp. When it was the first day he could make a call, I missed it because my phone was out of battery. Since then, I was always anxious about having a phone dead.
  • I carried 3 extra batteries, and yes, it was extremely burdensome. I wanted a charger that could naturally charge itself whenever and wherever, like an automatic watch.


  • The one thing that I carry all the time was a bag. So I wanted to make a ring that charges itself while shaking and receiving sunlight.
  • Drawing to be added


  • Wear it around a wrist or a bag.
  • When it charges, it blinks.

It already exists
