What types of vehicles can the JNC1224 jump start?

In 12-volt mode, it handles passenger cars, trucks, and SUVs. Switch to 24-volt mode for commercial trucks, buses, heavy equipment, and other vehicles running 24-volt electrical systems. The dual-voltage capability makes it one of the more versatile professional jump starters available.

How do I keep the unit charged between uses?

The JNC1224 has a built-in 1-amp automatic charger. Plug it into a standard wall outlet and it will maintain the batteries at full charge continuously. The charger is designed for permanent connection, so you can leave it plugged in without overcharging the AGM batteries.

How heavy is this jump starter?

The JNC1224 weighs 40 pounds. This is a professional-grade unit with dual AGM batteries, so it is significantly heavier than lithium-based consumer jump starters. The weight reflects the battery capacity needed to reliably start larger engines and 24-volt systems.

About this part

Product Details

Dual-voltage jump starting capability makes the Jump-N-Carry JNC1224 stand out from typical consumer battery boosters. With 3400 peak amps in 12-volt mode and 1700 peak amps in 24-volt mode, this unit handles everything from passenger cars and light trucks to commercial vehicles and heavy equipment that run on 24-volt systems.

Inside the heavy-duty polyethylene case are two sealed 22 amp-hour AGM batteries that provide the cranking power. The 46-inch number 2 gauge cables give you enough reach to connect from a convenient position without having to move the unit right next to the battery. Industrial-grade clamps ensure a solid connection to battery terminals, which matters when you are pushing thousands of amps through them. A battery status indicator gauge on the unit lets you check charge level before attempting a start.

The built-in 1-amp automatic charger keeps the unit topped off between uses, and Clore Automotive designed it for continuous charging so you can leave it plugged in and ready to go at all times. There is also a 12-volt DC outlet for powering accessories. At 40 pounds, this is a substantial unit built for professional and commercial use rather than casual glove-box storage, but that weight reflects the battery capacity needed for reliable heavy-duty starting.
