if the power goes out how are you going to recharge it?
In your car.
So your Hybrid electric vehicle is now your boat anchor battery charger for your super light
In your car.
I guess for me it has limited range and that is a drawback that despite its perks doesn't make it as useful and utilitarian as battery operated lights.
Is that all the data they give? Capacitors normally leak down similar to the "half-life" of certain molecules and radioactive substances (tritium night-sights for example). So if it leaks to near zero in 30 days, I bet its less than half charge after a week. Might even be less than half charge after a day. It is really hard to tell the leak-down rate with them telling us it is zero after 30 days.According the information in the above videos, a full charge will "leak" down to nothing after about 30 days.
