Best 100, 500, and 1000 Farad Supercapacitors

A standard capacitor uses a static charge to store energy. There is no electrochemical reaction involved in it. Voltage is applied to various negative and positive plates for the capacitor to charge successfully.

But not all capacitors are the same. The main difference between them is their capacitance level, which refers to how much of an electric charge they can store. Standard capacitors have a relatively low capacitance rating. That is why they’re used in a variety of electronic devices, such as radios.

Supercapacitors, on the other hand, have a capacitance that is thousands of times better compared to a standard capacitor. Any electronic device with charging cycles that vary in length will require a supercapacitor. You’ll find supercapacitors used to power larger electrical systems for things like elevators, cranes, and automobiles.

When capacitance is measured, the unit of measurement used is called a “farad.” Supercapacitors don’t all have the same farad capacitance; some have more than others. If you’re looking for a supercapacitor, you need to consider what electrical item needs it and how much energy it must store.

The Maxwell Durablue 16V 500-Farad Super Capacitor is a premium supercapacitor with 500 farads and a balance circuit board. If you want a supercapacitor with a longer lifespan and maximum efficiency, then you’ll be delighted with the Maxwell Durablue supercapacitor. It can handle anywhere from 8 million to a whopping 120 million recharging cycles. That should give you plenty of years of usage.

The high-power density of the supercapacitor is 6700 watts per kilogram. Most people use the Maxwell Durablue as a backup energy source, but it can also be used as a rechargeable battery too. The fast-charging time can last anywhere from 10 seconds all the way to 10 minutes until it reaches over 95% capacity. It all depends on how much demand is put on the supercapacitor.

The two most common ways to use the Maxwell Durablue supercapacitor is for a solar power system and car audio system. Its dimensions are 9.06 inches x 5.43 inches x 8.27 inches. The total weight of the supercapacitor is 10.34 pounds. Six 12-volt batteries are required.

5) Maxwell Durablue 16V 1000F

KOOBOOK 1Set(6pcs) 2.7V 500F Farad Capacitor Super Capacitor with Protection Board

Check on Amazon

The Maxwell Durablue 16V 1000F Super Capacitor is another premium supercapacitor from the Maxwell Durablue brand. The difference here is you will have a supercapacitor with 1,000 farads rather than 500 farads. This extra energy storage capacity makes it ideal to use with a solar power system, hybrid car battery, home audio system and more. It is marketed as an ultracapacitor because of its high level of capacitance.

All the other specifications are similar to the 500-farad model. The supercapacitor’s high-power density is 6,700 watts per kilogram, which makes it suitable as a backup energy source or as a rechargeable battery. Since it can also handle between 8 and 120 recharging cycles, most people love to use the 1000-farad version as a rechargeable battery. The total weight of the unit is 15.4 pounds. It will require twelve 12-volt batteries.


Now you should have enough knowledge about the best 100, 500 and 1000-farad supercapacitors that are on the market today. If you’re unsure about which supercapacitor is compatible with your particular DIY project, make sure you do further research or ask a professional.
