How to Charge a Portable Jump Starter

Has your car ever refused to start because the battery is out of juice? Leaving the headlights on all night will do that, and it is a huge pain to wake up to a car that won’t turn over.

However, this is why they make emergency devices such as portable jump starters. A portable jump starter is used in combination with jumper cables to start a car battery.

Instead of having to connect jumper cables to another car, you can use a portable jump starter. However, these do also need to be charged. In other words, they contain a battery which must be first charged. So, how you charge a portable jump starter is what we are going to discuss in this article.

Charging Your Jump Starter

Keep in mind that there are 3 main methods which can be used to charge your portable jump starter. Which one is best for you really depends on where you are and the tools which you have available to you.

Using An Electrical Outlet

The most commonly used method to charge a portable jump starter is by using an electrical outlet. This is also the simplest method to use. It really could not be any easier, because if you are near an electrical outlet, all you have to do is plug in the power cord of the portable jump starter and let it charge completely.

Most of the modern portable jump starter units come with AC power cords as well as indicators which tell you how much battery life they have, and how long it will take for a full charge to be achieved. If you want to preserve battery life and longevity, it is always recommended that you charge it 100% of the way. This is the best method to use if you need to jump start your car very soon and if it has no power.

Using Your Car’s AC Adaptor

Another common method of charging portable jump starter is by using the AC adaptor in your car. Even modern cars often come with a cigarette lighter port, which also doubles as an AC adaptor. Most cars even come with the AC adaptor included so you can plug it right into that cigarette lighter slot. This is convenient because you can just use your car to charge the portable jump starter, instead of having to go find a power outlet.

It will take longer to charge the portable adaptor with a vehicle’s AC outlet, but it still works. If you don’t have electricity in your home, for whatever reason, this makes for a really good backup option. However, beware that if your car is dead and you need to jump start it right now, of course, you will not be able to use dead car battery to charge a portable jump starter. This is a case where you will need to have the jump starter already charged.

Using Solar Energy

If there is one thing that is for sure, it is that solar energy is becoming more popular due to its clean energy nature.

Furthermore, it is also becoming more popular as solar energy tech is increasingly developing, is readily available, and much cheaper to buy. There are now many consumer items, such as portable jump starters, which allow you to charge them using solar energy. However, not every jump starter is going to allow for this, but most modern ones should, as it is a great backup in case you have no electricity and your car battery is dead.

The solar chargers used for these jump starters are however quite bulky, heavy, and take up a lot of room. There is also the fact that they will only charge a portable jump starter in direct and strong sunlight.

Indirect sunlight, such as on a cloudy day, is not going to be sufficient to really charge one of these starters. However, it is a good backup to have, and it is a cost-friendly alternative, as long as there is good sunlight for you to use. These solar units, depending on the brand and how new they are, can also be prone to a range of mechanical failures, so it is best not to solely rely on them.


So, we would recommend using a power outlet to charge your portable jump starter, but if possible you can use the vehicle’s AC adaptor, and it is always wise to get a model that can be charged using nothing more than sunlight.
