Buying Guide to Buy the Best Solar Car Battery Chargers
The Availability of collection for suitable solar car chargers are bountiful. Despite that, it’s always a matter to reconsider what is the “best” choice for your specific needs. Here we initiate a very understandable guide that will try to fulfill your buying requirements. The guide generated here not only gives a handful of information but also focuses on your specifications. Mostly what we try to keep on the first line is that the guide meets up your queries. So it’s a better approach to go through the guide a little consciously, so it can be at your full help.
Is it a must thingy?
Gadgets always have a cool impact on a certain field of work and this is not less than that. Being a gadget lover the solar car battery charger’s coolness is out of boundaries. Even if you’re not too familiar with the Gadget world, it’s still a smart choice for you to keep this in your cart.
This charger has a working principle that more or less works as a boost mechanism. In a situation where your battery is about to shut down, this can save your back. So, having a solar car battery charger is a helping hand to your emergency situations.
The batteries follow three types of technology- Amorphous, Monocrystalline, Polycrystalline, which increases the conversion process.
Supplying discontinuous voltage supply, the batteries simply rev up their durability. Most of them work in any weather condition. These can also be used in case of other types of vehicles. Here are some features to be noticed:
Trickle!
This trickle charging system is quite efficient to keep your battery charged even if the manual power source is turned off.
It helps the depletion of the charge to be less and keeps the battery moderately charged for a long period of time and takes less time to charge while driving as well. This means if the charge is required, it charges the battery up to the need. So the battery doesn’t get overcharged. Rather it has a rechargeable working principle.
Controlling Charge
The consumption of batteries has a limit that should be monitored evenly for keeping the battery life long. This charge control helps to limit the power that is drawn to the batteries so that it is not overpowered. If the battery always gets charged too much it can cause an explosive situation.
The proceeding charge controlling mechanism lessens the risk of having a disabled battery. To pump up a dead battery, these chargers aren’t that much of a helpful. But for moderate charging, most of these keeps the optimum voltage of 12V.
Level of Power
This remarkable device can generate up to a very optimum level of power about 12V, starting from at least 2V (some also provide a higher voltage of about 18V) that is a kick start to the batteries. Power is calculated in Watts here, and in the market, there is a handsome number of chargers that can generate power up to a high rate.
For example, Schumacher battery maintainer can come with 5 different levels of power- 10W, 2.4W, 4.8W, 5.5W, 6W. Others have more variation in this level of power, which is simply used up to needs.
Easy Operation
Some additional apparatus is added with most of the chargers available on board. These include- Alligator clips, Solar panel, Charge controller, Car cigarette lighter charger. The crocodile clip or alligator clip can be easily connected to the battery for charging purposes. Cigarette chargers also give a handy to charge up the batteries. All it needs is to be plugged in with the battery. The installation process is less painful, which makes it a user-friendly one.
Portability
One of the most significant features is that it’s portable. When it is impossible to provide charges to your car’s battery it gives you a smooth escape from unnecessary headaches.
The panel can be easily attached to near the window, or the car’s dashboard, so it can absorb enough sunlight to initialize the operations.
Technology and the panels
The Amorphous technology is the most efficient one to convert energy up to 22.5%. There’s the polycrystalline tech which is a little bit less effective. Then comes the monocrystalline one. However, these technologies also measure how flexible the panels are when mounted.
The panels come with variances of dimensions, which is also an easier measure to choose the necessary one for you. Most of the panels are created with protective glasses or some PVA sheets, for which they can bear a certain amount of loads. For mounting the panels, in most cases, suction cups are provided.
Why Should We Turn to Solar Battery Chargers?
Though it is not a highly modified gadget that can revive a dead battery from its off functioned state, solar chargers bring the much-needed breakthrough. Renewable energy always works with efficiency and the vital part is that it works without harming the surroundings. We experience the same case here.
This charging mechanism is user-friendly, eco-friendly, doesn’t harm the batteries. Moreover, it increases the longevity of battery life. In case of a situation of emergency, these solar battery chargers are your life savior.
It is not a must to have a solar charger, but if we can lessen the consumption of other non-renewable energy and little more conscious about the total fact, it won’t cause us any harm, rather it will be game-changing matter.
However, we see other charging gadgets (which of course do not follow the usage of green energy), might have high work efficiency and experience. But it has limitations like- the batteries losses its durability, overpowered charges can cause explosive occurrences.
If the limitations are gonna hurt with significance, you can shift our vision to these sustainable sources of energy. Kick-starting the battery with a strong power source we can hereafter switch to solar battery chargers, which will even keep the battery charged up to needs.
So we can undoubtedly say solar systemic chargers have rigid effectiveness over other forms of chargers.
