Supercapacitor, also known as ultracapacitor, supercondenser, electric double layer capacitor (EDLC) or pseudocapacitor, is an electric capacitor that has an unusually high energy density when compared to common capacitors, typically on the order of thousands of times greater than a high capacity electrolytic capacitorCompared to batteries, supercapacitors are capable of more than ten times the power and more than thousand times the cycle life. These are two main reasons why engineers choose them over batteries in different applications. Supercapacitors are proven energy storage devices that can replace conventional capacitors or batteries in many applications that require much more energy than what conventional capacitors are able to provide and that also require higher power outputs that batteries cannot provide

Interesting devices
Testing for patio lights, supercapacitors can take a very large input current over a short duration. With solar panel they can charge at 10 to 20 amps far quicker than a rechargeable battery. I eventually used some bigger super capacitors to do the job. Do NOT charge above the rated voltage!
