Safe, Reliable Help in Any Emergency — No Pre-Charging Required

Dead batteries don’t announce themselves. Whether it’s from long-term parking, battery aging, extended use of headlights, cold weather, or electrical drain, a weak battery can leave you stranded without warning.
When that happens, your options are limited—calling roadside assistance, waiting for help, or asking strangers. All of them cost time, money, and unnecessary stress, especially in unfamiliar places.
The Autowit Super Cap 2 solves this problem with next-generation supercapacitor technology. It doesn’t need to be charged in advance and doesn’t rely on fragile lithium batteries. Simply connect it to your vehicle, let it absorb residual battery power, and start your engine within minutes.
Compact, safe, and built for extreme conditions, the Autowit Super Cap 2 gives you peace of mind knowing you’re prepared—anytime, anywhere.

Key Features

Battery-Free Supercapacitor Technology: Unlike conventional jump starters that rely on lithium batteries, the Autowit Super Cap 2 uses advanced supercapacitor technology. Supercapacitors store and release energy extremely fast, offering excellent charge–discharge efficiency and an exceptionally long service life. This allows the unit to deliver powerful starting current within minutes.

No Pre-Charging Required: The Super Cap 2 draws a small amount of residual power from your vehicle’s battery and rapidly amplifies it to generate the energy needed to start the engine. Because it does not use a lithium battery, there’s no need for routine charging, topping up, or long-term battery maintenance. It’s always ready when you need it.

Superior Safety Design: With no lithium-ion or lead-acid battery inside, the Autowit Super Cap 2 eliminates common risks such as overheating, swelling, leakage, explosion, or fire. This makes it a safer, lighter, and maintenance-free alternative to traditional jump starters.

Reliable Performance in Extreme Weather: Battery-based jump starters often fail in harsh conditions. The Super Cap 2 operates reliably in extreme cold down to -40°C (-40°F) and withstands high temperatures up to 70°C (158°F). It’s ideal for winter climates, hot desert environments, and unpredictable outdoor conditions.

Long Lifespan & Cost-Effective: Because supercapacitors do not rely on chemical reactions, they do not degrade like batteries. The Autowit Super Cap 2 offers a lifespan of over 10 years and supports more than 1 million jump-start cycles, making it a highly economical long-term solution.

Wide Vehicle Compatibility: Designed for vehicles with a 12V system, the Super Cap 2 supports:

Gasoline engines up to 7.0L
Diesel engines up to 4.0L
Cars, motorcycles, tractors, and motorboats

Additional Practical Features:

Intelligent safety protection against reverse polarity and short circuits
Compact and lightweight design for easy storage in your car
Clear status indicators to guide proper connection and operation
Eco-friendly design with no disposable battery waste
