Types of Jump Starters: Which One Is Right for You?

Choosing the right 12V lithium battery jump starter depends on your vehicle and personal needs. Two main types of batteries exist inside jump starters.

  • Lithium-ion jump starters
  • Lead acid battery jump starters

Engineers design jump starters with lithium-ion batteries to be lightweight and compact for car use. Lead-acid batteries are optimal for larger vehicles like trucks and SUVs. Their heavy duty design provides more power.

When considering a portable jumper, keep in mind the specific features that best fit your circumstances:

  1. Size and weight: Consider how portable it is for easier storage.
  2. Battery capacity: Evaluate amperage needed for your vehicle.
  3. Additional features: Assess the presence of USB ports, integrated flashlights, or air compressors


Think about these factors to find a reliable jumpstarter that provides peace of mind on the road.

How to Safely Use a Jumpstarter: Step-by-Step Guide

Using a jump starter correctly ensures safety and effectiveness. Begin by parking your car on a flat, stable surface and turn off the ignition. This step helps prevent any mishaps during the process.

Find your vehicle's battery, typically situated beneath the hood or in the trunk of the car. Check for any damage or leaks, as these can pose hazards. Confirm that the jump starter shows a full charge before you begin.

Follow these steps to safely jump-start your vehicle:

  1. Attach the positive (red) clamp to the positive terminal on the car battery.
  2. Secure the negative (black) clamp to a metal ground on the engine block.
  3. Once the jump starter has indicated its ready to deliver surge, you're ready to proceed.
  4. After connecting the jumpstarter, attempt to start your car. If it fails to start, pause briefly and attempt again.
  5. Once your car starts, proceed with disconnecting the jump starter cables.
  6. Remove the clamps in reverse order: negative first, then positive.

Always wear gloves and eye protection for added safety. After jump starting your car, run the engine to help recharge the car battery. Disconnect all clamps safely to avoid sparks or damage.

Never connect the black clamp to the negative terminal directly. Not all jump starters come with reverse polarity protection, and connecting them improperly to battery terminals may create sparks. Maintain a safe distance from moving parts in the engine. This prevents accidental injury while working under the hood.

Regularly inspect and maintain your jumpstarter to ensure it's ready whenever you need it.
