What Makes the Autowit Supercap 2 a Top Portable Jump Starter?
How Does the Autowit Supercap 2 Work?
The Autowit Supercap 2 uses supercapacitor technology to store and deliver energy instantly, bypassing traditional lithium-ion batteries. It charges in 60-90 seconds via a car’s cigarette lighter or USB port and can jump-start vehicles up to 20 times on a single charge. Its ultra-fast energy transfer makes it ideal for emergencies.
What Are the Key Features of the Autowit Supercap 2?
Key features include a 12V/24V compatibility, -22°F to 158°F operating range, waterproof design, built-in LED flashlight, and USB charging for devices. Unlike conventional jump starters, it requires no maintenance, has no lithium battery degradation, and operates safely in extreme temperatures.
Where Can You Buy the Autowit Supercap 2?
The Autowit Supercap 2 is sold on Amazon, Walmart, Autowit’s official website, and automotive retailers like AutoZone. Prices range from $120 to $160, depending on promotions. Verify sellers are authorized to avoid counterfeit units.
Why Choose Supercapacitor Over Traditional Jump Starters?
Supercapacitors charge faster, last longer (10+ years), and perform reliably in extreme temperatures. They’re lighter, safer (no explosion risk), and eco-friendly. Traditional lithium jump starters degrade over time and struggle in cold weather.
How Safe Is the Autowit Supercap 2?
It’s UL-certified with reverse polarity protection, spark-proof clamps, and overcharge safeguards. Unlike lithium batteries, supercapacitors won’t leak or explode. The absence of flammable materials makes it TSA-approved for air travel.
The Autowit Supercap 2 undergoes rigorous testing to meet international safety standards, including CE and RoHS certifications. Its military-grade casing protects against drops up to 6 feet, while the waterproof rating (IP65) ensures functionality during heavy rain or snowstorms. Users in Alaska have reported successful jump-starts at -30°F without performance loss—a scenario where lithium models typically fail. The built-in diagnostic system automatically prevents activation if voltage irregularities or short circuits are detected.
What Vehicles Are Compatible With the Autowit Supercap 2?
It works with gasoline/diesel engines up to 8.0L (12V) and 6.0L (24V), including trucks, SUVs, boats, and motorcycles. Not recommended for hybrid/electric vehicles due to voltage differences.
| Vehicle Type | Engine Size | Compatibility |
|---|---|---|
| Sedans (Honda Civic) | Up to 3.5L | Full Support |
| Pickup Trucks (Ford F-150) | 5.0L V8 | 12V Mode Required |
| Marine Engines | Single/Dual | 24V Configuration |
For agricultural equipment like tractors or construction machinery, ensure the battery voltage matches before connecting. The Supercap 2’s intelligent clamps automatically detect 12V/24V systems but cannot support electric vehicles’ 400-800V architectures.
How Does Temperature Affect the Autowit Supercap 2?
Supercapacitors excel in extreme cold (-22°F) where lithium batteries fail. High heat (up to 158°F) doesn’t degrade performance. However, prolonged exposure to moisture may damage connectors.
What Do Experts Say About Supercapacitor Jump Starters?
The Autowit Supercap 2 revolutionizes emergency power with its near-instant charge and durability. For drivers in harsh climates, it’s a game-changer,” says John Carter, Automotive Engineer at Redway.
Conclusion
The Autowit Supercap 2 offers unmatched reliability, safety, and longevity for emergency jump-starts. Its supercapacitor technology outperforms lithium alternatives, making it a smart investment for drivers prioritizing preparedness.
