A modern traveler finds it difficult to refuse the benefits of civilization when going on a trip. Who doesn’t take a smartphone, laptop, or camera on a journey? When you have the best solar car battery charger in your luggage, the problem with powering all batteries will be solved. It remains only to figure out how it works.

What Is Solar Car Battery Charger?

This charger turns a solar light into a direct electric current. Except being suitable for a car battery charging, it also works with various models of navigators, laptops, smartphones, cameras, and other portable devices.

The device itself consists of a crystal panel, a charge / discharge level controller, and a solar-to-electrical energy converter. Some of the models are also equipped with a buffer battery of several lithium cells, which allow the device not only to convert but also to accumulate the energy in order to give out charge even without sunlight. The most significant drawback for all the solar charges is a great deal of time for power accumulation.

Solar Car Battery Charger Working Principle

A portable solar car battery charger is a stand-alone system that can recycle energy from sun rays. Many models don’t necessarily need intense sunlight, being capable of accumulating a charging process even on cloudy days, although with the decreased efficiency (from 20 to 70%).

The main feature of such charger is power. The battery charging time directly depends on this indicator. The power itself depends on the characteristics of the light-catching panels.

However, how do solar car battery chargers work? How do they process sun energy? These devices work the following way: the crystals on the panel absorb solar energy, the converter recycles it into an electric current, which is supplied to the power source. When a car battery or any device connects to this source with the help of a cord, the accumulated energy gradually flows into a discharged device.

What Is Required For A Solar Car Battery Charger Working?

  • Battery. If the device doesn’t provide a drive, it can work only while being in a lit place. The solar chargers with the battery are capable of delivering charge at any time of the day, as well as being charged from any other sources via a USB port or sockets with a 220V connection.
  • Photovoltaic cells. It’s believed that the monocrystals are more effective in absorbing the sun rays their efficiency is 13-18%. The polycrystals have slightly lower indicator for about 10-12%. You can distinguish them with the naked eye the polycrystalline panels have a dark blue tint, while their competitors are black-colored.
  • Interface. A universal device for charging from the sun is equipped with an informative interface, where you can choose the desired charging mode. Some models are equipped with an indicator of the sunlight intensity, which will help determine the optimal location for a quick charge.
  • Protection. A priori, a security system from some kinds of external damage is present on all the solar chargers. There are also devices with enhanced protection that can’t be damaged by rain, dust, dirt, shock, etc.
