OBDMATE Car Jump Starter 800A — Super-Capacitor 12V, LCD Voltage Readout & Fast Recharge

OBDMATE JSC7100 is a battery-free, super-capacitor jump starter that delivers up to 800A peak cranking power to start 12V gasoline and diesel engines without precharging.

If you need a dependable, low-maintenance jump starter that works across a wide temperature range and won’t suffer from swelling or freeze damage like lithium packs, this capacitor-based unit is designed for instant, repeatable starts. It’s built for everyday drivers, hobbyists, and service professionals who want a compact, safe emergency starter that recharges quickly and shows vehicle voltage on an LCD readout.

How does this device start a car without a battery?

The OBDMATE JSC7100 uses super-capacitors to store and release large bursts of energy quickly, rather than relying on a stored-chemical battery. That design means no long-term self-discharge, minimal maintenance, and safe operation across extreme temperatures.

• 800A peak current suitable for 12V engines up to 5.0L gasoline and 3.5L diesel.
• No precharging needed before use—ready on demand after brief recharge cycles.
• Safer operation: no risk of fire, swelling, or freezing common to lithium packs.

Which vehicles and situations can it handle?

The unit supports a wide range of 12V vehicles and small engines, from cars and SUVs to motorcycles and lawn equipment. It also offers two start modes for different battery conditions to maximize success in emergency starts.

• Works with Cars, Trucks, SUVs, Pickups, MiniVans, Motorcycles, Motorboats, and mowers.
• Standard Start for partially charged batteries; Forced Start for very low-voltage batteries after a full charge.
• Clear LCD voltage readout helps diagnose battery condition before attempting a start.

How fast does it recharge and what are the charging options?

The JSC7100 supports three practical charging methods so you can top it up quickly wherever you are. The fastest options recharge the capacitors in minutes, keeping downtime minimal between emergency uses.

• Car battery charger (12V, 7A) or DC charger (12V, 5A) fully recharges in about 3 minutes.
• USB-C charging (5V, 2A) provides a slower full recharge in roughly 30 minutes for convenience.
• Charging status and power percentage are displayed on the intuitive LCD screen.

Is it safe to use in cold or hot weather?

Yes—the capacitor technology maintains reliable start performance from very low to high temperatures, avoiding the common failures seen in battery-based starters. This makes it suitable for seasonal use and for keeping in vehicles that face extreme climates.

• Operates reliably between -22°F (-30°C) and 140°F (60°C).
• No risk of freeze-related damage, swelling, or thermal runaway that affect some batteries.
• LCD voltage readout helps ensure safe connection and operation before cranking.

Who is this for: The OBDMATE JSC7100 suits drivers who want a rugged, low-maintenance emergency starter without the long-term risks of lithium batteries. It’s ideal for commuters, fleet operators, boat owners, landscapers, and motorcyclists who need quick, repeatable starts across a wide temperature range. Backed by a 30-day return policy and a three-year warranty, it’s a practical choice for anyone who values fast recharge times, clear diagnostics, and safer storage in vehicles or garages.
