How to Start a Car with Jump Starter?
First, make sure your portable jump starter is fully charged.

Jump starters rely on a battery as their power source. As a result, they must be periodically recharged. Always recharge your portable jump starter/battery booster pack after each use and at least once every 6 months. These jump starter batteries will lose their charge more quickly if left in the car during hot and cold weather. We recommend charging your battery booster packs before going on a long trip.
Usually an indicator light on the jump starter tells you when a recharge is necessary. Simply insert the power adapter into an outlet and charge the battery until the light indicates a complete charge. Check the manufacturer instructions for specifics, including what the light indicator colors mean (usually red/orange for charging and green for completed charge).
WARNING: Jump starting a car can be very dangerous. If you are not 100% certain what you are doing, call roadside assistance or a towing service. And always read your owner’s manual first!
Here’s how to use one:
  1. Make sure your jump-starter is fully charged.
  2. If not, plug it in and charge as directed.
  3. Identify the positive (look for the “P,” “POS,” or “+” symbol) and negative terminals (look for the “N,” “NEG,” or “-“ symbol) on your car battery. Most new jump-starters come with integrated cables, but if not, connect your own cables to the proper (positive and negative) posts on the jump starter.
  4. Identify the positive and negative clamps/clips on the portable jump starter. The positive charger clamp is red and the negative charger clamp is black.
  5. Do not allow positive and negative clamps to come into contact with each other.
  6. Connect the red clamp to the positive post (+ symbol or red cover) of the dead battery.
  7. Connect the black clamp to an unpainted, grounded metal surface somewhere on the vehicle’s frame.
  8. Once everything is connected, turn the jump-starter on as directed.
  9. After a minute or two, start the car.
  10. If the engine doesn’t start, let sit for a few minutes to give the battery time to charge and try again.
  11. The car started? Fantastic.
  12. Turn off the jump-starter’s power switch.
  13. Remove the clamps in reverse order; black clamp from the grounded surface, red clamp from the dead battery.
  14. It’s a good idea to recharge the jump-starter after every start.
  15. You’re done, congrats!
