Product Review: SuperCap 2 Battery-less Supercapacitor Car Jump Starter

In these unprecedented times now would be a great time for people to check out emergency roadside kits for their car because you never know when you’ll be facing an emergency, especially if you’re an essential employee who needs to commute. Recently, GadgetPlus, a global leader in innovative auto products, announced the debut of its second-generation AUTOWIT SuperCap 2 Car Jump Starter and the launch of their Kickstarter campaign.

Autowit’s SuperCap 2 is a great addition to your car emergency and/or home preparedness kit as it won’t require charging a lithium-ion battery overnight to operate. Instead, SuperCap 2 is a supercapacitor jump starter that uses your car’s dead battery to charge so your car is always running during emergencies.

Unlike traditional jump starters that require to be pre-charged before use, AUTOWIT SuperCap2 Jump Starter uses a car’s weak battery power, or any other external power resource, to charge itself first before jumpstarting a car instantly. Its supercapacitor technology activates power physically to keep users from risk of sparks or explosion. Therefore, pre-charging at home is not required, although the function is available to instantly charge within a few minutes from any power outlet.


AUTOWIT SuperCap 2 Jump Starter is compatible with most car types (Up to 7.0L Gas/4.0L Diesel Engine), offering 800A Peak/600A Instant Jump power. In the box, you will find the jump starter, alligator clamps, cigarette lighter, USB charging cable and carrying case.

After a short pre-charge, Autowit can be connected to jump-start your own car. All you do is connect the alligator clamps to the jump starter and the dead battery. Next turn on the jump starter using the button located on the side. Once connected accordingly then you start your vehicle and begin charging.

Lastly, once the vehicle has a full charge you can detach and store it in your trunk. As you can see it’s so small making it easy to store in most vehicles.

Generally, a lithium-ion battery jump starter has a lifespan of 2 to 4 years. However, AUTOWIT SuperCap 2 Jump Starter has a longer lifespan up to 20 years. Thanks to its built-in supercapacitor, the starter can withstand more than 100,000 times frequently repeated use in its lifetime.

It can also work in extreme temperature conditions (-40℃/40℉) during snowstorms or blizzards and resist high temperature (70℃/158℉), e.g. desert dry-heat environment. If your car battery is totally dead, don’t worry. SuperCap 2 can be applied to other quick pre-charge alternatives. 

The AUTOWIT SuperCap 2 Jump Starter is available at a discounted $89 ($149 MSRP) Super Early Bird Special via a Kickstarter campaign, please visit Kickstarter for more information
