Autowit – SuperCap 2 – Does it work?

Products seen in this video



Testing the Autowit SuperCap 2 on my brother in law’s jeep. His car has a charging system issue, and his battery is always dead. As you can see, it was at 8.2 volts when we started. The Autowit SuperCap 2 took 5 minutes to charge from the 8.2-volt battery fully, and it started the car without a struggle.


True Story… Imagine you’re working late on a cold and snowy winter night. You get your car door cleared off so you can start warming her up and dig for your snow removal tool. You turn the key click… click…, you try again, click… There is no one around, the building locked behind you on your way out and it’s cold. You call Triple A then sit and wait…


Fast forward a few months later, and your family gave you a cool Lithium-Ion battery jump-start device. You keep it charged and at the ready, every week checking the battery, and when you go to use it on your 5.7-liter magnum, you find it just doesn’t have the power to crank anything bigger than a 3.6-liter engine.


The Autowit SuperCap2 is probably one of the coolest things you can toss in your trunk and forget about until you need it. When Autowit contacted me to test this device, I was skeptical that it would work as described, but I was excited to put it to the test.


Imagine a device that comes with a cool carry case that you can toss in the bottom of your trunk and forget about until you need it. No charging, no maintenance! The Autowit SuperCap2 charges from your low battery in 3 to 5 minutes and will provide enough AMPS (800peak amps) to start up to a 7-liter engine. So charger and challenger SXT owners you’re good, 5.7-liter R/T owners you’re good, 6.4 Scat Pack and SRT owners you’re good, 6.2-Liter Hellcat and Redeye Owners you’re good! The elite Hellephant owners are hitting the 7.0-liter top range of the device.
