Buying Guide

The solar charger came about seeking to solve the problem of lack of electricity using a renewable energy source and free access for all.

Therefore, in this shopping guide we will show you in more depth how this product works, what are its advantages and how to choose the best one for you, check it out.


What is a solar charger and what are its advantages?

The solar charger is a device composed of a photovoltaic plate that, when receiving sunlight, becomes a source of energy to be transferred to the most diverse devices through a USB cable.This product is ideal for those who like to venture into places without electricity and even for everyday life, being used in cell phones, portable radios, digital cameras, tablets and flashlights in a simple and easy way.

Due to the fact that solar chargers need sunlight to function, the efficiency of the product is directly related to the intensity of the sun and the available light.

That is, on cloudy days the device will take longer to reach its full charge, while on strong days it will be charged more quickly.

How to choose the ideal solar charger model?

First of all, you should assess whether the solar charger you are considering purchasing is certified by INMETRO and follows the minimum safety specifications.The principle is the same as other portable chargers. If you do not follow the correct standards, the device can impair the functionality of your device and also put your safety at risk.

With regard to size, the vast majority of solar charger models available on the market take up little space and are light, but there are also the largest and heaviest ones.

On the other hand, the maximum voltage they reach is not very high. Therefore, before purchasing the charger, it is important to analyze the technical specifications of the battery of your device so as not to make a mistake in choosing and purchasing a low voltage model that will not be efficient.

Another factor that must be taken into account is the average time to recharge the product and whether it can be connected to other sources of energy, other than solar.

Not everyone has the availability to leave the device charging from sunlight for about 10 hours, for example. Whoever will make the most intensive use of the device should take this factor into consideration and choose the ones that have the fastest loading.

In addition, you must also analyze the number of inputs it has, if it already contains adapters for the most diverse devices and what is the length of the USB cable, since these are very variable factors.

Virtually all models are made of plastic, but there are variables such as being waterproof or fire resistant. It is worth checking this information and checking the best for you.

How much?

The prices of solar chargers vary considerably, but it cannot be said that the most expensive models are also those that have more features or quality.The most affordable model found in this guide costs about R $ 40 and the most expensive can reach almost R $ 300. The other options that are not even between the most expensive and the cheapest follow an average price of R $ 50 to R $ 60.

Where to buy?

On the internet, solar chargers are easily found in department stores like Amazon. In physical stores, it is possible to purchase the product in stores aimed at selling products for cell phones and/or computer items.


Did you know that in the not-so-distant future cell phones will be able to be powered by solar energy? A technology presented in the scientific journal Science by researchers at the University of Illinois in the United States says that soon, sunlight will be able to directly charge cell phones and other gadgets.

Purchasing criteria: Factors to compare solar charger models

The working principle of solar chargers is simple, but there are small differences that can be confusing when choosing. Therefore, to help you make the right decision about which product to buy, we have listed below the main points to be taken into account:

  • Voltage
  • Charging type
  • Recharge time
  • Presence or need for adapters
  • Portability and material

Check out each one of these items in detail, so you can make the best choice when buying your solar charger.


It is possible to find models with voltages ranging from 3.2 volts to 12 volts, for example. This margin can be exactly where the battery of the device you want to recharge is located.

Therefore, seek the technical specifications of your product before making the purchase. However a tip is that practically all are useful for charging cell phones, which makes the decision process a little easier.

Charging type

There are two types of solar chargers, those that are recharged exclusively with sunlight and those that also have the possibility of receiving other energy sources such as the car battery.

When choosing, it is worth analyzing which will be the best for you. In a camp without any type of electricity, the fact of having both options may not be valid. But for those who want to use the device also in the city, this is a differential.

Recharge time

As already mentioned, among the models available for purchase are those that need a longer period to be recharged.

Even though it is easy to do this procedure anywhere that is exposed to sunlight, if you purchase a charger that uses fewer hours to be recharged, the possibility of needing to use it and find it still uncharged is much less.

Presence or need for adapters

It is known that most devices have different model inputs. Therefore, you should check if the product you are buying already comes with the adapter needed to connect to your device or if you need to purchase an extra one to use it.

Portability and material

It’s no use having a solar charger that can’t be taken everywhere you need it, right?

Therefore, if your need is for a small and light device, analyze the measurements and weight of the product you are going to buy and check if it is ideal for the place where you want to carry it.

In addition, the material is also extremely important and, first of all, it must be resistant and of good durability. Variations like being waterproof are also a plus.
