It's smaller... it's thinner... it's lighter... it's the new SuperXCap.   I can see this amazing new 25 farad supercapacitor being used in millions of applications. What I really like about them is that they are stackable for almost any custom power solution. I should have a few samples in the next few days to work with.  I will report back to you and let you know how they work for me. These seem too good to be true. 

Millions of Applications - Smaller - Thinner - Lighter

25F is a meaningless specification without a working voltage. You might want to be a little more specific in the future.

Thanks for the message. You should be able to see the specs now. It was showing up on my side but not the site for some reason. It's fixed now. Thanks again! Greg

For us noobie's What is the relationship between capacitance and amp-hours? How does this device compare to the Eestor in terms of energy density?

Here is the answer on the above questions:

Retail price: 25F -$65 - 5F -$20.00
All prices in US Dollars, FOB Philadelphia

Connection between Capacitance (C) and Amp- Hours (Ah)"
Ah = 3600 coulombs.

In one Discharge cycle we take the 25F SuperXcap from 2.7V to 1.35V, and this causes the discharge of X Coulombs,
where X= CV , where C=25 F and V= Average of 2.7 Vmax and 1.35 Vmin = 2.025 V

X = 50.625 Coulombs, or 50.625/3600 Ah = 14 mAh

IOW, Our 25F can draw a current of 14 mA over a 1 hour discharge cycle.

Need more info... Dimensions, operating temp, voltage, life expectancy, etc. Need complete specs... Any manufacturer's web page?
