10 Best Super Capacitor Jump Starter 2025 in the United States

The Clore Automotive Jump-N-Carry JNC660 is a robust jump starter that's built to perform well in various situations, from cold weather to repeated jump starts. One of its standout features is the impressive 1,700 peak amps, which makes it suitable for starting larger vehicles, including trucks and SUVs. With a capacity of 22Ah, it provides reliable power and includes heavy-duty 46-inch cables, ensuring a solid connection to your vehicle's battery.

Durability is another strong point; the JNC660 is designed for tough environments, and the industrial-grade clamps contribute to its reliability. It even has a built-in voltmeter, which allows you to check the battery's status easily. Additionally, the built-in automatic charger ensures that you can recharge it without much hassle.

This jump starter weighs 18 pounds, which may be a consideration if portability is a priority for you. While it does offer a DC outlet for powering 12-volt accessories, the lack of USB ports may be limiting for some users. If you need a dependable jump starter that can handle larger vehicles and challenging conditions, the Clore Automotive JNC660 is an excellent choice. Its blend of performance and safety features makes it particularly appealing for car owners who want peace of mind on the road.

The Clore Automotive JNC325 Jump-N-Carry is a powerful jump starter, offering 2000 peak amps, making it suitable for jump-starting 12-volt batteries in vehicles with up to 8.0-liter gasoline and 6.0-liter diesel engines. This makes it a great choice for a wide range of users, from car owners to those with larger vehicles like SUVs and trucks. The heavy-duty 24-inch #6AWG jumper cables with full-size clamps stand out as a strong feature, ensuring efficient power delivery to the vehicle battery.

Additionally, the dual USB outlets allow for charging other electronics, and the built-in LED flashlight adds a layer of convenience for use in low-light conditions. The fast recharging capability via USB-C is another plus, as it reduces downtime between uses. The build and durability seem robust, supported by its UL2743 specification, which implies safety compliance. The jump starter is also portable, weighing only 3.94 pounds and having compact dimensions, making it easy to store and transport.

A notable feature is its ability to start completely dead batteries (down to 0.0 volts) using the Override function, although this requires careful handling. While the product does require a lithium polymer battery which might need periodic replacement, it is still relatively new and has proven itself in the market. Its versatility and additional features, like the 12-volt power outlet and the included carrying case, add to its appeal for anyone needing a reliable jump starter. However, for those seeking a super-capacitor-based jump starter specifically, it's important to note that this product relies on traditional battery technology.

The Autowit Super Capacitor Jump Starter stands out due to its innovative supercapacitor technology, which eliminates the need for regular pre-charging at home. This feature makes it very convenient, as it can quickly draw power from a weak battery in just a few minutes. With a peak current of 800 Amps, it's capable of jump-starting most gasoline engines up to 8.0L and diesel engines up to 4.0L, making it suitable for a range of vehicles including cars, tractors, and motorcycles.

The jump starter is highly durable, boasting a lifespan of over 100,000 uses under normal conditions, thanks to its heavy-duty build and supercapacitor technology. It's also designed to work in extreme temperatures, from -40°C to 70°C, ensuring reliability in various weather conditions. Safety is a top priority with this device, offering protection against reverse polarity, overcurrent, overload, and overvoltage, minimizing the risk of sparks or explosions.

Portability is another strong point, given its compact dimensions (11 x 5 x 2 inches) and lightweight (2 pounds), making it easy to carry around. However, one potential drawback is that it requires a weak battery to charge up, which might not be ideal in situations where the battery is completely dead. Additionally, while it includes a lithium-ion battery, the long-term performance of this component can be a concern. The Autowit Super Capacitor Jump Starter is a reliable, safe, and portable option for those needing a dependable jump starter without the hassle of regular maintenance.
