How To Use A Portable Jump-Starter To Start Your Car

If your car has a flat battery, you can easily use a portable jump-starter to get it going. Here’s what you need to do:

  • Check to ensure that the jump starter is fully charged
  • Open the bonnet of your car and look for the battery
  • Identify both the positive (+) and the negative (-) terminals on your battery
  • Also, ensure that the jump starter is turned off at this stage
  • Connect the red charger cable to the positive (+) terminal. This should always be done first.
  • Connect the black charger cable to the negative (-) terminal. 
  • Switch the jump starter on and start the car
  • Allow your car to idle for a couple of minutes with the jump starter still connected
  • Switch off the jump starter
  • Disconnect the black charger cable from the battery first
  • Disconnect the red charger cable from the battery
  • Clip the cables back into the jump starter and you’re now ready to go

It’s vitally important to charge your jump starter unit after you use it or at least once you get home again if you got caught with a flat battery while out on the road. Bear in mind that the battery in your jump starter will lose its charge more quickly if you store it in the trunk of your car when the weather is very hot or cold.

Even if you don’t use your jump starter very often, you should still charge it every 6 months so that you know it’s ready if you end up with a flat battery.

If your battery is continually going flat for no apparent reason, it might be wise to replace it with a new one. Or at least take it to an auto shop to get tested.

How To Use The Air Compressor On Your Portable Jump Starter To Inflate Your Tires

If you have a slow leak in one of your tires or you find that your spare is somewhat flat, you can add air to these to at least get you home. Bear in mind that the air compressor on your portable jump starter is mainly designed for emergency use. Whenever possible, it’s best to routinely inflate your tires at the same time as you’re filling up with gas.

Here’s how to inflate your tires with the air compressor on your portable jump starter in an emergency:

  • Make sure that the portable jump starter is fully charged because it will use the battery to power the air compressor.
  • Check the air pressure in your tire by connecting the air hose to the tire
  • Depending on the type of unit that you have, the tire pressure will either be displayed in a digital format or on an analogue gauge
  • Set the required PSI if your unit has this capability
  • Turn on the air compressor to inflate the tire
  • Some air compressors will shut off automatically when the required pressure has been reached while others will need to be turned off manually

In either case, you should not allow the air compressor to run more than 8 minutes continuously (check the manual as this could vary depending on the model you have). Therefore, you want to turn it off and allow it to cool down for around 5 minutes.

This stops the unit from becoming overheated which will cause a general failure in your air compressor. Also, remember to recharge your portable jump starter after you’ve used the air compressor before storing it away again.

Tips On Using A Portable Jump Starter With Air Compressor

Always ensure that you read the manual that came with your unit for any specific instructions. 

Make sure that you stay clear of the battery when you attempt to jump-start your car.

Before you attempt to jump-start your car, ensure that the battery is completely intact and that there are no leakages as this could lead to an explosion.

Frequently Asked Questions

Do you leave the ignition key on when attaching the jump starter cables?

No, the ignition key should be turned off and removed before attaching the jumper cables to your battery.

Will a portable jump starter charge a flat battery?

No, a portable jump starter is only designed to provide the necessary battery power to crank over the engine of your car. It’s the alternator on your vehicle that charges the battery.

What happens when you connect jumper cables incorrectly?

Connecting your jumper cables incorrectly could cause damage to the electrical circuits in your car and will most likely result in blown fuses.

What should you do after jump-starting a car?

The best thing you can do after jump-starting a car is to drive it around so that the alternator can recharge the battery fully. Even if you leave the car on and let it idle for 30 minutes, this should be enough to fully charge the battery. 

How often do you have to charge a portable jump starter?

To keep your portable jump starter in good working order, you should charge it after every use and at least every twelve months if you haven’t used it.

In Summary

A portable jump starter with air compressor is a useful tool to have as it will get you back on the road when you’re away from home. Plus, the air compressor on these units is also handy to have when you have a leak in one of your tires while you’re a long way from a repair shop or a gas station.
