The Autowit SuperCap 2 revolutionizes portable jump starting by using supercapacitors instead of traditional batteries. It requires no prior charging, drawing energy from your car’s weak battery within minutes to deliver a powerful 800 cranking amps. This battery-free, maintenance-free solution works effectively even in extreme temperatures as low as -40℃, offering unmatched reliability and convenience for emergency vehicle starting.

How Does the Autowit SuperCap 2 Work?

The device connects to your car’s battery terminals, quickly extracting residual power through its built-in supercapacitors in about three minutes. Once charged, it releases a high-current burst, up to 800 amps, to jump-start gas engines up to 7 liters and diesel engines up to 4 liters swiftly and safely.

What Makes Supercapacitors Advantageous Over Traditional Batteries?

Supercapacitors provide virtually unlimited charge cycles (over 100,000) and a lifespan exceeding 20 years. Unlike battery-based jump starters, they require no storage charging and are not prone to failure from inactivity or extreme weather, ensuring they’re ready whenever needed.

Which Features Enhance the Device’s Safety and Usability?

The SuperCap 2 includes intelligent protections against reverse polarity, short circuits, overcurrent, overload, and overvoltage. Its robust design prevents sparks and explosions, making it safer and easier to use compared to conventional jump starters.

Why Is No Pre-Charging Important?

No pre-charging means users don’t need to remember to recharge the unit at home; it charges rapidly from the car’s weak battery when connected. This feature eliminates the common failure point of jump starters being dead when most needed.

How Does It Perform in Extreme Temperatures?

The SuperCap 2 operates reliably in harsh climates, from -40℃ (-40℉) to 70℃ (158℉). This wide temperature range means it functions well in snowstorms, desert heat, or freezing conditions where traditional battery jump starters often fail.

When Is the Autowit SuperCap 2 Ideal to Use?

Ideal for road emergencies, it benefits anyone driving vehicles with large engines—cars, motorcycles, RVs, boats, and farm equipment—offering fast, dependable starts even in adverse conditions without assistance.

Where Can You Get the Autowit SuperCap 2 and Accessories?

The device and its accessories, including alligator clamps, USB charging cables, and cigarette lighter adapters, are available through major online retailers and specialty automotive stores.

Can the SuperCap 2 Charge Itself from the Vehicle’s Battery?

Yes, it can recharge by drawing charge from the vehicle’s weak battery, creating a self-sustaining jump start system that prepares itself when connected to the car’s terminals.
