What is a car cigarette lighter charger and what are its advantages and disadvantages?
This charger basically works like a USB adapter. It is connected directly to 12V cigarette lighter via a cable.
This category of chargers is the best solution if you want to use a fast and simple device. That may be the case if your car does not start. Or if you do not have time to open the bonnet and remove the battery cover.
In these cases, you can just take the charger in your hand, and plug it into the cigarette lighter.
Advantages of car cigarette lighter charger
- No technical know-how is necessary
- Very fast to use
- No dirty hands and tedious connection
- Compact design
Disadvantages of car cigarette lighter charger
- Weak performance during charging
- Significant risk of overheating
- Relatively short service life
It is important to ensure that the voltage of the charger matches that of the connected device. The charging current of the charger must be at least as high as that of the connected device. This is especially necessary if you want to avoid overheating the charger.
In addition, one must know that such a device is not the most powerful. In fact, it cannot fully charge a deeply discharged battery, even if it manages to get the car started.
As in the case of any charger, the car battery must have at least 20% electricity in order to give your car specific start-up assistance.
Which Car can I charge with a solar charger: Charging car battery with a solar panel
Basically all car batteries can be charged with a solar panel car charger such as cars, 4wd, caravans, RV, boats and farm equipment. Solar panel to charge 12v car battery could be used when any vehicles with 12v battery need topped up or drained. Trickle charge car battery solar panel should use in the case of drained battery or deep-cycle batteries.
What safety precautions should be taken during car battery charger use?
Best solar car battery chargers are already equipped with built-in safety measures. As mentioned before, they are short-circuit proof, spark protected and reverse polarity protected.
Do solar panels need maintenance?
Solar Panel Maintenance is not essential regularly as because most of solar panels are maintenance free. Whatever service period of a solar panel is around 25 years so its need little general maintenance such as cleaning dust, dirt and other debris on them which need cleaned for better solar charging performance.
A solar charger for car batteries is also called “solar car charger”. It fulfills the task of charging the car battery during its lifetime solar. This is usually charged by the alternator while driving.
If the motorcycle, car or camper is standing for a long time, the car battery discharges due to connected consumers and through a self-discharge. This is where the car battery Solar Charger comes into play: It ensures that the car battery is constantly charged.
In winter, when it is nice and cold, the car battery does not provide as much capacity as in summer. Partly the capacity drop is considerable. Thus, at -18 ° C only about 50% of the normal battery capacity is available. If the car is now for a long time, it comes to the further discharge of the battery.
On the one hand, as with all batteries and accumulators, this ensures self-discharge and, on the other hand, the discharge current through consumers.
The typical discharge of a modern car is about 85mA. That’s about 2Ah per day. It is best to compensate for this again.
The connection of a solar charger to the car battery is very easy. If there is the voltage on the car socket, even if the car is switched off, it is sufficient to plug the cigarette adapter plug of the battery protector into the car socket.
If there is no voltage, the charger is connected directly to the car battery (crocodile clips).
What performance does solar battery protection have to have?
The manufacturer’s specifications of the solar modules always refer to a solar radiation of 1000W / m2. Just stupid that this solar radiation is never reached in winter. The radiation intensity is then about one third compared to summer.
For example, a solar battery protection with 5 watts delivers approx. 2 watts maximum power in winter. Thus, the charger for the car battery reaches a charging current of about 150mA. These are sufficient for a trickle charge (the typical discharge of a car is about 85mA).
If the solar battery protection basically has little power, you should make sure that it is amorphous solar cells.
These provide a higher charging current in bad weather conditions. Furthermore, you should pay attention to the cable length.
Because the charger should be optimally aligned to the sun in or on the car. It may be necessary to bridge a few meters. Ideally, you park properly and put the battery protection on the dashboard. For larger solutions, such as my 20W battery protection, the module can be placed outside year-round. The cable lengths of 5 or 10m provide sufficient flexibility.
Charge Your Car Battery – anytime, anywhere: Simply connect the Solar Charging Panel to the cigarette lighter and place it in the sun, e.g. on the dashboard. For longer lifetimes, clamp it directly to the battery.
Start through – in any weather: Not only in sunshine but also in cloudy weather is your solar charging panel is a secure electricity supplier.
Safety first: your battery is not overcharged and is also protected against discharge via the solar panel. How to keep your loading panel permanently in operation.
