How Does the JNC660 Work as a Jump Starter?
The JNC660 delivers 2000 peak amps through its clamps to jump-start 12V batteries in cars, trucks, boats, and motorcycles. Its microprocessor detects correct polarity and prevents sparking, while the battery status indicator ensures optimal charge levels. Users connect the clamps to the battery terminals, power on the device, and start the vehicle within seconds.
What Safety Features Does the JNC660 Offer?
The JNC660 includes reverse polarity protection, spark-proof technology, and overload protection. These mechanisms prevent accidental damage to the vehicle’s electrical system or the jumper itself. Its rugged casing also resists water and dust, meeting IP65 standards for durability in harsh conditions.

The reverse polarity protection automatically disables power flow if clamps are attached incorrectly, while spark-proof technology activates before connecting to live circuits. Overload protection shields against voltage spikes from alternators during jump-starting. For extreme environments, the IP65-rated casing ensures functionality in rainstorms or dusty off-road conditions. A thermal sensor also prevents overheating during prolonged use.
| Safety Feature | Function |
|---|---|
| Reverse Polarity Protection | Blocks current if clamps are reversed |
| Spark-Proof Technology | Prevents arcs during clamp connection |
| IP65 Casing | Resists water jets and dust ingress |
Can the JNC660 Charge Mobile Devices?
Yes, the JNC660 has a 12V DC outlet, two USB ports (5V/2.4A), and a 19V laptop port. It can charge smartphones, tablets, laptops, and small appliances like tire inflators. The 18Ah lithium battery provides up to 50 phone charges or 15 hours of LED light operation on a single charge.
How Does the JNC660 Compare to Traditional Jump Starters?
Unlike bulky lead-acid jump starters, the JNC660 weighs 18 lbs and features a compact design with a carrying handle. It requires no maintenance, self-recharges via a wall outlet, and offers multi-functional use as a power bank. Traditional models often lack safety protections and degrade faster in extreme temperatures.

Lead-acid jump starters require monthly recharging and occupy twice the space of the JNC660. Their average lifespan is 3-5 years compared to the JNC660’s 8-year lithium-ion durability. Performance-wise, traditional units lose 30% efficiency in freezing temperatures, while the JNC660 maintains 95% capacity from -4°F to 140°F. The integrated digital display also gives real-time diagnostics unavailable in basic models.
| Feature | JNC660 | Traditional Jump Starter |
|---|---|---|
| Weight | 18 lbs | 35-50 lbs |
| Temperature Range | -4°F to 140°F | 32°F to 104°F |
| Lifespan | 8 years | 3-5 years |
What Vehicles Are Compatible with the JNC660?
The JNC660 supports gasoline engines up to 6.5L and diesel engines up to 4.0L, including cars, trucks, SUVs, RVs, boats, and motorcycles. It’s incompatible with 24V systems or hybrid/electric vehicles. Always verify your battery’s voltage and capacity before use.
How Long Does the JNC660 Hold a Charge?
The lithium-ion battery retains 80% charge for 12 months when stored properly. Recharge every 3-6 months if unused. A full recharge takes 3 hours via the included AC adapter. Avoid exposing it to temperatures above 140°F or below -4°F to prevent capacity loss.

FAQs
- Can the JNC660 Jump-Start a Completely Dead Battery?
- Yes, if the battery voltage is above 2V. For batteries below 2V, use the JNC660’s manual mode after consulting the vehicle’s manual.
- Is the JNC660 TSA-Approved for Air Travel?
- No. Lithium-ion batteries exceeding 100Wh require airline approval. The JNC660’s 178.56Wh capacity means it cannot be carried in checked or carry-on luggage without prior authorization.
- What Warranty Comes with the JNC660?
- Schumacher Electric provides a 1-year limited warranty covering manufacturing defects. Damage from misuse, water submersion, or unauthorized repairs voids the warranty.
