Product Details

No need of precharge at home | Jumpstart your car in 3mins | Built-in supercapacitors| Works in extreme weather | Safe with no battery


With no need for pre-charging in advance, the ability to work in extreme weather and an amazing long lifetime, Autowit SuperCap 2 Jump Starter comes to your rescue whenever you get stranded.

How many times do you find a drained jump starter when you need it? Unlike lithium-ion jump starters that require regular pre-charging at home, SuperCap 2 is a supercapacitor jump starter that only requires a quick charge from your weak battery to get your car started. This is extremely convenient as you don't need to remember to pre-charge your jump starter.

The supercapacitor draws up and amplifies the small amount of power remaining in the car's battery, creating the power needed to start the engine in less than 3 minutes. Its supercapacitor technology activates power physically to keep users from the risk of sparks or explosion.

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

Another advantage of SuperCap 2 is that you can store it while drained for a period spanning years and it will only need a few minutes to be instantly charged, making it a maintenance-free product.

The battery-based jump starters always fail to work in cold weather. SuperCap 2 can work in extremely cold weather (-40℃/40℉) during snowstorms or blizzards and resist high temperature (70℃/158℉), e.g. desert dry-heat environment. It’s ideal for road warriors who seek adventure in extreme weather conditions.

Say good-bye to the traditional lithium-ion jump starters forever!

Autowit SuperCap 2 Car Jump Starter with supercapacitors replaced the lithium-ion battery jump starter and will boost your dead battery with ease whenever you need it.

In addition to the cars, SuperCap 2 can be widely used for motorcycles, tractors, and motorboats equipped with a 12V battery. And it can handle up to 7.0 liters for gasoline cars and 4.0 liters for diesel cars.

If your car battery is totally dead, don’t worry. SuperCap 2 can be applied to other quick pre-char alternatives. 

After a short pre-charge, Autowit can be connected to jump-start your own car.
