One of the main fears of drivers is running out of battery in the middle of a long trip, so it is convenient to always have a charger on hand that can save you in those uncomfortable moments. With this in mind, the market offers all kinds of options, including battery chargers. To help you choose one of these devices, we have prepared a useful guide to buying the best car battery charger, which will be of great help, especially if you are looking for the cheapest model.


The first step you should take, when wanting to purchase a device of this type, is to consider your budget and ask yourself how much the device costs, so that you can know if it is within the range of money you plan to invest in it.

However, you should not worry, since the market offers a wide variety of models with all kinds of prices. But, it is important that you keep in mind that sometimes cheap is expensive, so if you choose a low-cost charger, you could run the risk of buying a defective one or one that does not meet your real needs.

For this reason, many experts suggest that, when making your purchase, price is not the main requirement.

Battery Type

Although many users do not have this concept in mind, the reality is that there are multiple types of battery and, although most chargers work with different types of batteries, you need to make sure that it is compatible with the one in your vehicle. In this way, you can be sure that you have chosen the right model for you.


One of the most important aspects for anyone looking for a new car charger is the versatility that the device will provide, especially if you need it to be used with a wide variety of vehicles.

Whether you are the owner of a mechanical workshop or a person with various types of means of transportation, acquiring a battery charger compatible with cars, motorcycles, trucks, jet skis and boats is the most appropriate.

This is the most important technical requirement that you should take into account when making any comparison of car battery chargers, since it will tell you the output voltage and, therefore, the type of battery that can work with it.

Most of the chargers that you can find on the market have an average of 12V, so they are suitable, for the most part, for compact vehicles. However, you can also find models for very specific uses and that have a suitable voltage level for your needs.

To choose correctly, you will only need to know the voltage of your vehicle’s battery, but if you are interested in a multifunctional model, it is recommended that you check whether it can be regulated.


When choosing a new car battery charger, the amperage is another factor that you should be aware of, since, in addition to other benefits, it will determine the speed with which the battery will be charged. However, keep in mind that high charging speed is not always a good thing, as it might not be as effective.

Therefore, most experts indicate that it is more advisable to choose a charger with automatic detection of amperage, as well as voltage. These are known as smart chargers and they stand out for being very simple to use, since they do not require any configuration by users.


Finally, before making your decision, do not forget to look at the level of protection and security offered by the device. The car battery charger you choose should have features that prevent possible damage to a battery, such as overloads, short circuits, overheating, reverse polarity, among others.

On the other hand, keep in mind that it may be the case that you need to use it outdoors and even under extreme weather conditions, so it is suggested that the device comply with aspects such as, for example, the IP65 standard.

Also, you should not forget to check the type of insulation that the charging clamps have, since, if it is of low quality, sparks could occur that could damage or compromise the battery.
