Jack Okie,

EEStor has yet to deliver one of their supercapacitors for independent testing. Not even a lab model.

Many in the industry think that they are fudging by not taking into account dielectric saturation i.e. capacitance at low voltage is way higher than capacitance at high voltage. Not to mention the fact that capacitance at room temperature can be 2X to 3X higher than capacitance at 20° below or 100° above zero F. You will note that all their “specifications” call out the capacitance at about 73° F.
