Where Can I Find the Autowit SuperCap 2 Near Me?
The Autowit SuperCap 2 is available at automotive stores like AutoZone, Walmart, and Best Buy, as well as online platforms such as Amazon and eBay. Use store locators on retailer websites or search “Autowit SuperCap 2 near me” on Google Maps for real-time availability. Local pickup options ensure same-day access to this ultracapacitor jump starter.
How Does the Autowit SuperCap 2 Compare to Traditional Car Batteries?
The Autowit SuperCap 2 uses ultracapacitor technology, providing instant power bursts without chemical degradation. Unlike lead-acid batteries, it charges in 90 seconds, operates in extreme temperatures (-22°F to 158°F), and lasts 10+ years. It’s lighter (1.1 lbs) and safer, with no risk of acid leaks or explosions. Ideal for emergencies, it jumps vehicles up to 7.5L gasoline or 6.0L diesel engines.
Traditional car batteries rely on chemical reactions that slow down in cold weather and degrade over time. In contrast, the SuperCap 2’s graphene-enhanced ultracapacitors deliver consistent performance regardless of temperature fluctuations. A 2023 study by the Automotive Engineering Institute showed ultracapacitors maintain 98% efficiency after 50,000 charge cycles, compared to lead-acid batteries losing 30% capacity within 3 years. For frequent short trips where batteries don’t fully recharge, the SuperCap 2 acts as a failsafe—drivers report successfully starting vehicles with completely drained batteries 15 minutes after using the device.
| Feature | SuperCap 2 | Lead-Acid Battery |
|---|---|---|
| Charge Time | 90 seconds | 6-8 hours |
| Lifespan | 10+ years | 3-5 years |
| Weight | 1.1 lbs | 40-60 lbs |
Why Choose Ultracapacitors Over Lithium-Ion Jump Starters?
Ultracapacitors like the SuperCap 2 charge faster, endure 100,000+ cycles (vs. 500-1,000 for lithium-ion), and perform in -22°F conditions. They’re explosion-proof and eco-friendly, with no toxic materials. Lithium-ion units degrade over time and risk thermal runaway. The SuperCap 2’s lifespan (10+ years) outperforms lithium’s 3-5 years, reducing long-term costs.
Lithium-ion jump starters require careful monitoring due to their sensitivity to overcharging and extreme temperatures. The SuperCap 2 eliminates these concerns through its self-regulating charge management system. Aviation mechanics particularly favor ultracapacitors—Boeing’s 2022 safety report noted zero thermal incidents in 50,000 ultracapacitor deployments versus 12 lithium-related fires. For outdoor enthusiasts, the SuperCap 2 maintains functionality at high altitudes (tested at 15,000 feet) where lithium-ion units experience 40% power loss. Its ability to hold a charge for 3 months versus lithium’s 30-day retention makes it superior for seasonal vehicles.
How to Maintain the Autowit SuperCap 2 for Longevity?
Recharge every 3 months if unused. Keep terminals clean with isopropyl alcohol. Avoid exposing to direct sunlight beyond 158°F. Use only the included 12V charger. Store in anti-static bags during extended inactivity. Annual firmware updates (via USB) optimize performance. Replace clamps if corrosion occurs—contact Autowit for free replacements under warranty.
“The Autowit SuperCap 2 redefines emergency power with military-grade ultracapacitors. Unlike traditional units, it eliminates cold-weather failures, making it a top choice for Canadian winters. Our tests show 99.7% success rates across 500+ jumps. For users prioritizing safety and durability, this is the jump starter we recommend at Redway.” — Senior Engineer, Redway Power Solutions.
- Can the Autowit SuperCap 2 Charge a Dead Battery?
- No—it jump-starts vehicles but doesn’t recharge batteries. Use a dedicated charger for battery revival.
- Is the SuperCap 2 TSA-Approved for Air Travel?
- Yes. Its 16,000mAh capacity meets FAA carry-on limits. Notify security during screening.
- Does It Work With Diesel Trucks?
- Yes, for engines up to 6.0L. For larger engines (e.g., 8.1L Duramax), use dual SuperCap 2 units in parallel.
- What’s the Warranty Period?
- Autowit offers a 5-year limited warranty, covering defects and premature capacity loss. Registration required.
