this is a new project ideea " charging a phone using a fidget spinner"..... Ac in dc and an old smartphone ( I will not use my phone for sure for this project))
one thing is for sure probably I will have to spinn 18 hours for a completeMake sure you remove the battery from the phone, as it will discharge the battery faster than a fidget spinner will charge it.
Be prepared to sit there flicking the spinner for a number of days as well.
It takes VERY little energy to light an LED - and there are far more efficient ways to generate electricity from human mechanical input - a practical example (used throughout the world) would be a bicycle driven generator.

And right there shows the folly of human powered anything. The recharge times for even basic items is way beyond realistic for most anyone to deal with.
Olympic cyclist gets wiped out making 1 slice of lightly toasted bread with a bicycle generator. ~one minute at ~ 700 watts output or ~ 12 watts of power. Just enough to charge a cell phone.
Guessing a fidget spinner generator would take well over 24 hours to charge phone provided that it could even break the minimal power requirement levels to even start and maintain the actual charging process which I doubt being most phones need at least a stable 5 volt .5 - 1 amp source to work which is way beyond what finger power can produce steady.
and ........ fidget spinner generator 2
using a single neodymium magnet disc (under the fidget spinner which is not moving)
you can consider me a child if you wish but this is an educational generator which will help teachers to explain better how electricity is created and it may be something more important...... (but it will transform in a off topic discussion)
And we dont mention he wasnt allowed to connect it to the grid, but like i say its pretty cool. And in several generations time it will pay back its costs...........
