We all believe it happened at least once to live the not exactly pleasant experience of trying to turn on the car and discover that the battery has run out. Once upon a time the only solutions were: contacting a friend with a car and the charging cables or hoping to find an electrician nearby.

Buyer Guide to Choose the Best Battery Chargers
If you happen to use your car or motorbike sporadically and therefore often leave it stationary for prolonged periods of time, it may happen that the battery is discharged and that the vehicle is therefore unable to start.
A charger therefore represents a perfect solution to remedy this problem and avoid … walking. Typically it looks like a small case or a cuboid, better if equipped with a handle that facilitates its transport, equipped with power supply and cables (equipped with pliers) to connect to the poles of the battery to be recharged.
At the top of the list of aspects to consider before purchasing a product of this type there are two factors: the amperage of the battery to be recharged and the speed with which you want the recharge to be carried out.
In addition, you will also have to decide if you need a portable model , to always have with you in the trunk of the car so you can use it wherever you are in case of need, or one that needs electricity and to be kept in the garage.
Full Charge or Fast Reboot?
As mentioned, it is very important that you know exactly what type of battery is mounted on your machine. For example, if you drive a petrol sedan it is likely that it is a model with 12 V power supply, while if you are behind the wheel of a van with a diesel engine it is likely that it is a 24 V.
There are also different types of batteries, each of which works differently and has advantages and disadvantages. The most common are those with lead-acid, then there are nickel-zinc batteries, AGM and those with gelatinized acid (called gel). In general, all of them need some maintenance and need to be recharged.
This is why it is important, when choosing a charger, to decide whether to go to a model for emergency starting, to be used only in exceptional cases, or on a charge maintainer, to be used from time to time to recharge complete with the battery which, inexorably, over time tends to discharge.
This operation must be carried out using an ad hoc charger, capable of providing a low amount of charge to the battery but for an extended period of time.
Let’s say that an operation of this type requires a dozen hours and it is advisable to carry it out by leaving the appliance running all night, relying on one of the products made by the best brands in the sector.
An Intelligent Model
Traditional chargers do not have a battery analysis function. For this, comparing the prices, you will notice that the price is much lower than that of other intelligent models . But how do these more expensive but also more advanced devices differ, to the point of deserving the name of… brilliant?
The normal charging devices sold on the market in fact supply energy as long as they are connected and cannot “understand” when the operation is completed. The risk is that if you forget to unplug it, the battery may be overcharged and damaged.
The intelligent models, on the other hand, have different phases for desulphating, reconditioning, recharging and maintaining all types of batteries, because they “dialogue” with them, minimizing the risk of an excessive or insufficient charge.
Their intelligence derives from the fact that they are equipped with an internal microchip that deals with managing the various aspects of the operation as well as inverter technology that ensures a perfectly stable output current.
Reading the technical data sheets and the reviews you will easily find the intelligent models and you can opt for the one that best meets your needs, including spending.
Speaking of car accessories, you may need a good portable compressor , to be used not only for tires but also for inflating inflatable boats, bike wheels, etc. In this case you can find our reviews on the dedicated page.
Fast Charging
One of the advantages of the Deca 0400204 car charger is the hours it takes to make your vehicle’s battery come back as new. In fact, in about 8 hours the battery is fully recharged. This is also thanks to the power supplied which stands at 130 W.
During the recharging hours you can rest assured that the operation takes place without in any way damaging the battery or the rest of the car’s electrical system.
This is thanks to the presence of active protection devices that keep the charging phases under control. The clamps to be connected to the battery terminals are also protected by a system that prevents any reverse polarity.
The article, although considered by many users to be very good especially in consideration of the selling price, is not without defects. For example, some owners of the charger are not satisfied with the 15A fuse which is considered to be undersized compared to its task which is to keep the protection systems active.
Also Suitable for Workshops
To function, the Deca charger must necessarily be connected to an electrical outlet. This feature limits its use a little. In fact, if you remain stranded in areas without electricity it is not practically usable. On the contrary, in the garage or even in workshops, where there is an electrical outlet, it does its job properly.
The supplied cable is over two meters long, and therefore you will hardly need an extension to use it. Even the weight of only 4 kilos allows you to move it to various areas of the workshop, where you need it, without much effort.
Few Frills
The product does not offer many functions which, on the other hand, are found on other level car chargers. In addition to the possibility of seeing the amperage, thanks to an indicator located on the front, there are no other peculiarities that can be useful in certain situations such as, for example, the regulation of the current supplied.
Despite this, we are faced with a robust product (it is built in metal with air intakes placed on both sides) designed to last over time and which becomes ideal for those who need to recharge the battery in reasonable times and nothing else.
The voltage of this battery must be between 12 and 24 volts. Keep in mind that if the battery model to be recharged has a different voltage, the product is practically unusable.
