Powerful battery booster jump box for jump starting cars, boats, motorcycles and more. Jumper cables vs boost. What is the difference between jumper cables and a NOCO lithium jump starter? There are many methods on how to jump start a car. Jump starting a car with a dead or severely discharged battery can be done by supplying it with power from an external source. Traditionally, people have used jumper cables as a temporary connection between both vehicles and their batteries, however, jump starting technology has come a long way in terms of efficiency, safety, and ease of use. The first innovation in portable jump starting came in the form of large, heavy, lead-acid jump starters. Lead-acid jump starters fixed several problems associated with jump starting, like the need for an additional vehicle. Even with the advantage of portability, lead-acid jump starters still pose the same safety risks as jumper cables, which require knowledge of the correct battery terminal polarity, and are often too heavy to be effectively “portable.” With advancements in technology, and a little bit of ingenuity, came the lithium-ion car jumper box. These types of jump starters, as the name suggests, are powered by a lithium-ion battery rather than a lead-acid battery. The benefit of lithium technology is energy density, allowing the jumper packs to be up to 80-percent smaller and significantly more lightweight than their lead-acid counterparts.
