Joule thief capacitor charger

“Supercaps“ are rated for voltages around 3V maximum. They are in capacitance of Farads hundreds or even 1000 and have leakage current of several mA >5mA. A joule is can work with low voltages and can produce high voltages with low current. So whats the idea to put a joule thief between 9V and a supercap?

I think he meant charging a capacitor to super high voltage. Not charging a super capacitor to high voltages...

All capacitors are super 😂

Originally I wanted a way to use my dead batteries and the idea was just to charge a regular capacitor to high voltages because I needed a high voltage to discharge through a coil. Later on I decided to connect my Emergency radio and also a flashlight to one or multiple super capacitors for operation instead of batteries. You are correct super capacitors work on low voltages, but thinking that limits you only to low voltages is only limiting yourself. Two ways to make use of the low voltage presented by super capacitors it to use many of them in series to get your desired voltage, or you can also use a dc-dc converter to raise the voltage. I don't know all of the possibilities but I figured I'd share this because it's easy to build and you can; with an imagination, do quite a bit with this circuit.
