Startup Idea : Fidget Spinner That Charges Your Phone

Often times, our phones run out of battery when we are traveling and have no access to electricity anywhere near. A power bank may come handy but what if you use the power in a power bank as well, or you forget to charge the power bank! That's when this little device can come handy! It's like a fidget spinner that is attached to a dynamo. When you spin it, it charges your phone. When your phone has 1% of charge left and prepare to shut down, you can use it to make that one emergency call! This fidget spinner and phone charger is useful especially for people who travel a lot or enjoy camping. I'm looking for a number of co-founders with engineering or product design background to kickstart this business. Someone with video editing or ecommerce website development experience will also be welcome. This little spinner can be easily manufactured by Chinese vendors. Let's see what we can do!
