4Pc 1.5F Farad Electric Double Layer Super/Ultra Capacitor 5.5V KamCap K

Exactly what I was needing for an electronics project. 👍

Nice, large capacitors. I use mine as a power store for simple TTL circuits. Remember to check your breadboard for current limiting components. At least one of my breadboards does not allow more than 300mA of current through so when these capacitors were charged via the breadboard they appeared to hold a rather small charge, but once I connected them directly the 5V power supply leads and then to the breadboard they stored significantly more charge (this is a not a fault of the capacitor just a heads up for another buyers, if your capacitors don't seem to hold much charge it may not be the capacitor that is at fault).-1 Star for nitpicky things such as the terminals are not quite spaced right for a breadboard (they can be bent to fit). Nothing to significant, but enough to not be a "perfect" product.

Well no wonder. They stay loaded more time than the traditional ones, but, at last, they discharched.
