TL;DR: Through June 11, the Autowit SuperCap 2: 12V Battery-Less Portable Jump Starter is on sale for just $109.97 instead of $149.99 — that's a savings of 27% for a limited time. To get it in time for Father's Day, order by June 5.


The Autowit SuperCap 2: 12V Battery-Less Portable Jump Starter is an excellent option for anyone who owns a car, motorcycle, tractor, or boat with a 12V battery. Grab one for only $109.97 (reg. $149.99), but order by June 5 for delivery before Father's Day.

Whether you drive your car to work, your motorcycle to Sturgis, or your boat to cruise around the lake, chances are good you may find yourself with a dead battery at some point. Having the SuperCap 2 on hand offers an extra layer of protection for emergencies.

Whereas lithium-ion jump starters hold a pre-charge and thus require some maintenance, the SuperCap uses a supercapacitor to gain a charge from your vehicle's weak battery. This means you don't have to constantly maintain its battery life to be prepared for emergencies. 

Here’s a closer look at how this jump starter really works:

  1. When the vehicle’s battery is dead, grab the SuperCap out of its case.

  2. Hook up the alligator clamps to the negative and positive terminals on the battery.

  3. The SuperCap draws out some of the battery's remaining energy to charge itself. You could also power it up with a portable charger.

  4. Once the supercapacitors are charged, press the red button on the SuperCap.

  5. Turn the vehicle’s key, and it's supposed to start right up.

The manufacturers state that the SuperCap has been tested to withstand more than 100,000 times of repeated use, which is probably more than most users need. It’s also designed to work in temperatures of -40 to 158 degrees Fahrenheit. 

Give your loved one (or yourself!) a gift that could come in handy in the case of an emergency.
