Best Supercapacitor Jump Starter Buyer's Guide: Benefits, Battery Vs. Supercapacitor

First of all, what is a supercapacitor jump starter?

It's a device that uses a weak current from a power bank or your car's system to jump start the vehicle. You don't need any batteries to provide the power; the device uses whatever you have in an emergency to help you out.

Battery jump starters have been around forever; they are used at car dealerships and repair services. They fit their purpose and will be used until the new tech doesn't fill the whole industry. But as we all know, technology doesn't stay still, so it's clear there's something better than a toxic, lead-acid battery.

If you need a portable jump starter, a supercapacitor type may become your best choice. It's not as bulky and dangerous and can fit in your emergency kit easily. Supercapacitor jump starters are a bit more expensive than regular ones, but their benefits make any investment justified.

We'll review all the advantages to show you why it's high time to change your regular jump starter to a new-generation one.

Benefits of a Supercapacitor Jump Starter

Let's take a ride over 9 advantages of supercapacitor jump starters.

1. A Combination of Safety and Power

A decent supercapacitor jump starter is 50-60 times more powerful than a regular battery you have in a vehicle. Such superiority allows it to charge a battery in several minutes, which leads to another benefit of time-saving.

While a lot of people consider it an unnecessary investment, just think about the hours you can spend waiting for a tow truck. Instead, it's much better to have an emergency kit in your car and be ready for anything, especially if you drive to other cities often.

Plus, the option is very safe, as there are no sparks and fire hazards if you use it properly.

2. Wide Variety of Applications

Depending on the model, you can utilize such a jump starter in a wide variety of vehicles and engine types. Most modern options are suitable for both diesel and gas engines (up to 5l, if it's a regular model).

Use it for:

3. Little to No Maintenance

The only maintenance you'll have to perform is pre-charging the starter and storing it properly when it's not used. It charges in minutes, and the storage rules are as for any other appliance: little to no humidity, around room temperature, protective case.

This is a suitable option for busy people and those who don't want a lot of hassle when using jump starters.

4. Close to Immediate Charge

Compared to calling for assistance and waiting for it to arrive and do magic tricks with your car, a supercapacitor jump starter charges almost immediately.

A minute to several minutes is needed for sufficient charge (10 to 15 A) for using the jump start mode. This is very useful when you're driving to another city, and the car stops in the middle of nowhere. Modern starters are suitable for use in very low and very high temperatures, so you're safe no matter what weather is outside.

5. Wide Working Temperature Range and Long Service Life

The larger part of modern supercapacitor jump starters' work can operate equally well in temperatures as low as -40F. You don't have to worry about being stranded somewhere during a snowstorm and have no battery power left.

Such devices are capable of working in temperatures up to 158F as well.

Kind tip: Always check if the option you're going to buy has CE, FCC, and/or RoHS certification. It's also wise to check the information on the warranty beforehand. If there's none, make sure to contact the manufacturer or choose a similar model from another seller that provides fuller info.

6. Flexibility of Use

The versatility of use is a benefit because these starters aren't marketed as replacements for the lithium-ion batteries when it comes to jump-starting procedures. Supercapacitors can be successfully utilized to improve the power and functionality of those batteries by storing extra energy and providing it to the battery when necessary.

Such processes won't affect the lithium-ion batteries' longevity or functionality because supercapacitor jump starters work with high energy levels in a lower power density.

7. Quick Starter Motor Turn-On due to Low Internal Resistance

Low internal resistance is one of the most important perks of such jump starters. They can discharge very high electrical currents that are necessary for a successful jump-start of a vehicle. Such currents turn on the starter motor easily, which adds to the convenience, safety, and ease of use of such devices.

8. High Durability

A decent supercapacitor jump starter will serve you for up to 20 years. This is quite impressive compared to the longevity of lithium-ion batteries (up to 5 years). The devices don't need to charge for a long time; the materials used for their construction are sturdy and durable. So, it's an investment for ages.

9. Long-Term Cost-Effectiveness

As a consequence of the durability point, such jump starters are very cost-effective in the long run. You may buy a top-notch device for quite a sum of money, but it will pay off really fast with the ease of use and longevity.

It's very important to choose a model from a reliable manufacturer. When you find one, there will be nothing to worry about. You will get a warranty for a year or more, all necessary details in the package, and maximum durability.

Battery Vs. Supercapacitor

This information is for beginners who need a deeper understanding of the difference between a supercapacitor and a battery.

Batteries' functions are clear to most modern people. They power up electronic devices without the use of external cords. There's a battery inside your phone, remote, etc. Chemical energy within the battery is transformed into electrical energy, giving devices power for a limited amount of time.

Most common batteries are rechargeable, having a lifespan of 500 to 10,000 charging sessions.

Now, a capacitor.

A capacitor is a small device that holds a certain amount of electrical energy in a field. It's a passive element and has two terminals on the sides. It's like a microSD card, but instead of files and photos, a capacitor stores electrical energy between its plates.

A supercapacitor takes the best from both worlds. It holds a larger amount of energy and can be charged and discharged much more frequently.

Major Differences

Both options have their buyers, and both are great for their purposes. We find supercapacitors an amazing solution when it comes to jump-starting your vehicle. It's much safer than using bulky batteries; it's quick and simple.

FAQ on the Use of Supercapacitor Jump Starters

If you need more information, the following answers to the most frequently asked questions will help.

How does a supercapacitor jump starter provide power to the vehicle battery if there's no battery in the device?

The device uses power from your car cigarette lighter, a residue power left in the batter, or another source. There should be clear instructions in the user manual that comes in the package. Different models need different amounts of power from the battery or another source to jump start a car.

When using it for the first time, make sure the manual is somewhere nearby so that you can guide yourself through the process.

What USB cable should I use for charging?

It's either micro USB or standard USB. The cable often comes in the package, so there's nothing to worry about. But if it's not, find out what kind of cable you will need in advance to see if you have one or can purchase one as soon as possible.

Domestic or foreign manufacture?

Both niches have a lot of great models. However, most buyers tend to stick to domestic manufacture. Meeting the requirements, most reliable American brands use domestic materials, workforce, and locations to create such devices.

Some reviewers state that they wouldn't buy Chinese devices, thinking they are of poor quality. We haven't used a lot of China-manufactured appliances, but we understand that buying domestic products helps support the economy as well.

What is used to charge this if your battery is dead?

If the battery is fully dead, you will need another device that holds electricity to charge your jump starter. It can be anything that is connectable via USB (a power bank, etc.). You'll need it for several minutes just to jump start the vehicle.


All the items we've mentioned on the list have been tested and provided amazing results. The supercapacitor jump starter technology proves to be helpful time after time, buyer after buyer.

While you need to get used to it and have something to charge it with while on the go, the tech is very easy to use and provides a high level of comfort. It's time-saving and cost-effective as well!

In the future, we may see new improvements in such devices. Maybe you won't need to have a power bank with you, and it will be possible to jump start your car using solar-battery-powered jump starters. We'll see!
