1. Type of jump starter - lithium-ion or lead-acid?

Despite being small and compact, do not underestimate the power of lithium jump starters. These things are tiny but incredibly powerful, some models are even capable of jump-starting an 18-wheeler truck! More importantly, lithium batteries have a longer lifespan and retain their charge for longer when not in use.

2. Battery size and voltage - 6v, 12v or 24v?

Normal jump starters will typically work on batteries ranging from 6 to 12 volts while industrial-grade ones designed for medium and large trucks can go up to 24 volts.

Keep in mind that jump starters can be used for virtually any vehicle with a battery, from cars and trucks to motorcycles, watercraft, snowmobiles, and lawnmowers.

The vast majority of cars, pickup trucks, and SUVs run on 12-volt batteries while smaller vehicles like motorcycles sport 6-volt batteries.

Recommendation: Check your battery’s voltage in order to buy a product that will work on your vehicle. If you have a motorcycle and a car, look for models that have adjustable voltage settings.

3. Size & type of engine - 4, 6 or 8 cylinders? Gas or diesel?

The size and type engine your vehicle has is a crucial component of choosing the right jump starter for your car. Vehicles with bigger engines have bigger batteries and diesel engines require larger batteries than gas engines.

Recommendation: Check your car’s engine size and type to make sure the jump starter you get will be able to jump-start your car. We always recommend getting a more powerful one to be on the safe side.

4. Safety features

Did you know that some jump starters are safer than others? Quality jump starters will come with reverse polarity, overcharge and short circuit protection, anti-spark technology as well as back-feed protection.
