Is it reasonable to power the LEDs from a ioistor for a toy?

Question

Electronic components

I want to make a toy as a gift with a pair of LEDs. Because I'm a little environmentally obsessed and don't want to use lithium batteries (a small toy, a "finger" battery won't fit).
I came up with this idea:
1) Use an ionistor to store electricity
2) Charge via USB, take the required voltage from the divider.
I know electronics at the level of the very basics, criticize the idea. The uniformity of the glow of the diodes is not required, I will connect directly. How viable is the idea? Will there be a glow for at least a few hours?
Thank you.

Good afternoon! Theoretically possible, but most likely they will flicker, only you need to add a 100 ohm resistor, thanks to which the voltage consumption will decrease slightly. My forecast - an hour from the strength will glow.
My husband tried to do this when they decided to create New Year's toys on their own, in the end they spat and bought at www.100suvenirov.ru/prazdniki/podarki-na-novyy-god...
There is less trouble, and the prices are loyal, if the cat breaks - no sorry)
And good luck in this matter!
