FAQ

How do this charger work?

Car solar battery chargers operate on the principle of converting sunlight into electrical energy or heat. Modern solar chargers consist of a chain of solar cells — semiconductor devices that convert solar energy directly into electric current. The process of converting solar energy into electric current is called the photoelectric effect.

 Do solar panels work at night?

No. Solar panels do not work in the dark. It can only be used in the daytime.

Do I need find direct sunlight to charge my solar panel?

No. There is not necessary to find direct sunlight.  But it is advisable to find the most sunlight place.

Can I use it if I have not electricity car?

It is a portable charger that converts solar energy into electrical energy. You can use it to recharge any device, including a device in your car.

How many watts it can create?

Using it, you can generate 5 watts of electricity. But there are models that can produce up to 18 watts. It depends on a lot of factors. You can find a model that will be the most suitable for your needs.

What are the differences between different models for a car?

All solar panels work on a similar principle. The difference is that some models have a regulator. A device with this regulator prevents overcharging the car battery. Using such solar battery chargers you will increase its life.

Buyer’s Guide

Solar battery chargers are the best way to prevent unexpected situations connected with the lack of electricity in the car. Choosing such a gadget, pay attention to what situation you need it. Firstly look at the maximum charge that this or that model can produce.

Pay attention to the presence of a regulator that will prevent overcharging the car battery. Models with the regulator will not only provide you with electric energy in unforeseen situations but will save the car’s battery from overcharging and prolong its life. Also, pay attention to whether it is waterproof and weatherproof as well. For installation outside the car or for vehicles such as snowplows, lawnmowers or tractors, it is certainly better to choose waterproofed models. When installing a full-night battery on the windshield inside the cabin, you can choose a non-waterproof model.
