Performance overview
You’ll notice the JNC660 is all about practical muscle: strong starting power and a battery designed to hold charge for multiple starts. It’s not the smallest or lightest option, but it’s optimized for reliability and repeated use, which matters when you need power at a moment’s notice.
Jump-starting capacity
This model delivers 1700 peak amps, which gives you the punch required to start many gasoline engines and most light trucks under normal conditions. In practice, you’ll find it starts sedans, SUVs, and light-duty trucks with fewer attempts than smaller jump starters.
Battery life and charging
The 22Ah Clore Proformer battery is a sealed lead-acid type made to balance capacity and durability, giving you several starts per full charge and a good shelf life when maintained properly. Charging times vary based on the charger you use and battery condition, but you’ll typically expect hours to a full charge, not minutes — plan accordingly if you rely on it frequently.
Voltmeter and gauge
You can check the on-board voltmeter and battery status indicator gauge to see how much stored energy is available before you attempt a jump start. That little bit of feedback helps prevent surprises and gives you confidence when assessing a weak battery.
Build and design
You’ll appreciate that the JNC660 is rugged and built to take regular use, with a protective housing and a form factor that balances portability with durability. The blue casing is immediately recognizable and the handle is designed to be comfortable even when you carry the unit over short distances.
Portability and weight
Because it uses a heavy 22Ah lead-acid battery, the unit is heavier than compact lithium jump starters, but that weight is tied directly to its capability and durability. You’ll want to keep it in a trunk or workshop where weight isn’t a problem — it’s made to be moved when needed, not carried long distances for hours.
Cable quality and clamps
The included 46-inch heavy-duty #2 AWG cables are thick enough to carry significant current with minimal voltage drop, which is important for effective jump-starting. The clamps are heavy-duty as well, designed to grip securely and maintain a safe connection even when conditions are less than ideal.
How to use the Clore Automotive Jump-N-Carry JNC660
You’ll find it easy to use if you follow a clear sequence, and you’ll minimize risk by maintaining common-sense safety habits. The following steps walk you through a typical jump-start procedure and include pre-checks you should perform before connecting anything.
- Position the vehicle and unit: Place the jump starter on a stable surface and bring the vehicle into park with the ignition off. Make sure both the jump starter and the vehicle are in a dry, well-ventilated area and that you’re not in contact with moving engine parts.
- Inspect cables and clamps: Before attaching, check for frayed insulation, corrosion, or loose clamp jaws, and confirm the cable length is sufficient for a secure connection. You want full clamp engagement on the battery terminals (or recommended chassis ground) for both safety and performance.
- Read the voltmeter: Look at the on-board voltmeter and battery status gauge on the jump starter to confirm it has enough stored charge to attempt a start. If the indicator shows low or depleted, charge the jump starter fully before proceeding.
- Connect the positive clamp: Attach the red clamp to the positive (+) terminal of the dead battery; make sure you have a solid connection with no risk of slipping. Keep metal tools away and avoid touching both clamps together.
- Connect the negative clamp: Attach the black clamp to a good chassis ground away from the battery and fuel system — a painted bolt or unpainted metal part of the engine block is typically recommended. This reduces the risk of sparks near the battery.
- Start the vehicle: Attempt to start the engine. If it doesn’t start within a few seconds, wait briefly and try again — avoid continuous cranking for more than a recommended few seconds at a time. If the vehicle starts, let it run for a few minutes to stabilize the electrical system before disconnecting.
- Disconnect clamps in reverse order: Remove the negative clamp first, then the positive clamp, and stow the cables carefully to avoid damage. Check the jump starter’s voltmeter again and, if needed, recharge the unit after use.
Safety features
You’ll benefit from inherent safety improvements compared to older, improvised jump methods — built-in insulation, proper cable gauge, and clear indicators reduce risky guesswork. The device is engineered to minimize sparks and improper connections when used properly, but your awareness and correct procedure are still essential.
Safety tips and best practices
Always double-check terminal polarity before connecting clamps to prevent severe damage to vehicle electronics and the jump starter itself; a reversed connection can cause extensive harm. Also, avoid using the jump starter near open flames or in enclosed areas with poor ventilation; lead-acid batteries can emit flammable gases under certain fault conditions.
