We are excited to introduce a second new Jump-N-Carry lithium model, the heavy-duty Model No. JNC345, 12 Volt Lithium Jump Starter. The JNC345 is an ideal shop tool, combining robust jump starting power with numerous features that deliver utility, convenience and safety, including UL2743 safety certification, USB outlets to power small electronics, 12 Volt power supply capability and a high intensity LED work light. Its higher capacity makes it a great option for larger vehicles, extreme cold weather starting and longer cranking vehicles, such as diesel starting.

Delivering 550 Start Assist Amps of starting power, the JNC345 can tackle a wide variety of starting tasks in numerous application environments, including automotive, marine, light truck, agricultural and fleet starting. It can start most V8 engines up to 10L gas engines and 10L diesel engines. It also features the ability to jump start totally dead (0.0V) batteries – simply confirm that you have made a proper connection and press and hold the override button to force the unit on. It’s that easy.

The JNC345 incorporates numerous features to make jump starting safer for the operator and vehicle being serviced, including reverse polarity protection, backfeed protection, over-voltage protection, short circuit protection and overheat protection. It features safety certification by TUV laboratories to comply with the UL2743 lithium jump starter safety regulation.

The JNC345 features two USB outlets to power small electronics. Also included is a 12 Volt Female Adapter, allowing the JNC345 to power accessories from its 10A DC output or be used as a memory saver when changing out a vehicle battery. It features a high intensity LED work light for use in nighttime starting or other emergency situations. Charging is fast and easy with the wall charger (with pin jack) and its automatic charging routine. The unit comes packaged in a convenient zipper case for easy transport and storage.

  1. Hi,

    Please consider creating a page on your web site that compares your various versions of battery chargers to make it easier for customers to decide what’s best for them. Page should have product names in column headers and features in the row labels.

    That being said, what’s the difference between your lithium jump starters? And are they better than your lead acid starter? πŸ™‚


    1. Vlad – Thanks for your question/comment. Lithium has come a long way in the last several years, improving its cold weather performance and reliability. That said, it typically is not as good of a store of energy as the equivalent starting power lead acid model. That’s a good thing when it comes to jump starting – its energy density enables it pack a lot of punch even when it is relatively light weight. But, if you want to use it for a power supply, it may not meet your needs the way a lead acid unit would. Similarly, if you are a frequent user (multiple jumps per day) or are starting difficult to start vehicles, you may prefer lead acid. Similarly, if you expect to be performing a lot of cold weather starting, lead acid may be preferable. Although lithium has come a long way in this regard, it is still quite a bit more sensitive to temperature than lead acid. Hope this helps.

      With regard to comparing our two new lithium models, the JNC435 has about 25% more starting power, has a better cold temperature rating (-30˚F vs -10˚F) and longer cable reach (40″ vs 24″). These are the key differentiators. I would say that, if you are regularly starting larger vehicles or diesel vehicles, live in an extremely cold temperature area, or are starting many vehicles per day, then the JNC345 will better meet your needs.

      Thanks, Jim from Clore Automotive
