I'm interested in knowing whether anyone has developed a power bank that has only capacitors inside, instead of being based on batteries like usual. I know it would take up a lot more space for the same capacity, but the reason I want this is because it could charge completely during a short trip, and then last a long time in parking mode.
A normal battery-based power bank could take quite a long time to charge up if it is completely dead. If my daily trip is only 5 minutes long, that's not enough time to charge the battery bank. However, it might be enough time to completely charge a capacitor bank if it had a smart current limiting circuit on it. What do you guys think?
