Can a jump starter that isn’t fully charged be used?

Have you ever been in a situation where your car won’t start and you reach for your trusty jump starter only to find that it’s not fully charged? Don’t worry, all is probably not lost. While it’s ideal to have a fully charged jump starter on hand, there are still some steps you can take to try to use it if the need arises.

Why does every driver need a jump starter?

Know the limitations

When the emergency jump starter source is not fully charged, its effectiveness may be compromised. A jump starter works by providing a burst of energy to start a vehicle with a dead battery. If the jump starter doesn’t store enough power, it may struggle to provide the necessary starting power to get your car running.

However, that doesn’t mean you can’t try using a partially charged jump-start power source. In some cases, it may still have enough power to start your car, especially if the battery isn’t completely drained.

Steps taken

If you find that your emergency jump starter is not fully charged, you can take the following steps:

Evaluate the battery charge: Check the indicator light on the emergency jump starter to know the remaining charge, preferably no less than 70% charge. For example, Powkey’s Q6 percentage power display allows you to clearly see the remaining power; if the indicator light shows it, it is best to maintain 3 bars or more of power, such as Powkey’s best-selling A9/H9 jump starter.

Q6 Emergency jump starter

If only partially charged, proceed with caution. Connect the jump starter: Connect the jump starter to the car’s battery terminals as you normally would – make sure the polarity is correct.

Wait a few minutes: Give the jump starter a few minutes to transfer some power to the car’s battery.

Try to start the car: Try to start the car. If it doesn’t work the first time, try again. Sometimes, a partially charged jump starter can still provide the power you need to get your car running.

When to avoid using a partially charged jump starter

In some cases, it is best not to use a jump starter that is not fully charged. If the battery is completely dead or you’ve tried to start your car multiple times without success, it may be time to seek professional help.
Using a partially charged jump starter in these situations may not only be ineffective, but it may also damage the jump starter itself.

Check the remaining power of your jump starter before going out and fully charge it, or use a car charger on the road; as a prudent approach, you can also carry a small solar panel to use sunlight to provide sufficient energy for the jump starter.

In conclusion, while using a jump starter that is not fully charged is not ideal, it is still worth a try in certain situations. By following the steps above and exercising caution, you may be able to successfully start your car with a partially charged jump starter.

Remember, the best thing to do is keep your jump starter fully charged and ready to go. But in an emergency, a partially charged jump starter may still be useful.
