Best Solar Phone Charger: Harnessing Sunlight for Your Communication Necessities

The days when people used to go to nature with little or no technology, having in mind to escape from the comfort of the modern world and return to a more primitive state, have left us behind. That’s not necessarily a bad thing, since a GPS can keep you from getting lost, and a good smartphone app can tell you what mushrooms you should not eat. Unfortunately, most smartphones do not have long-lasting batteries, but choosing the best solar phone charger you can afford can solve that problem for you.

In this article, we will tell you all about solar cell chargers, how to choose the best models on the market, the advantages and disadvantages involved, to help you decide which solar charger you need for your walk.

Load performance

Devices powered by solar energy are, in fact, among modern technological revolutions. But if you are thinking about buying a solar charger, you need to know the technical concepts and the science behind them, so you can be prepared to operate them. Not to mention that you can buy a device that suits your needs according to its wattage and amperage.

The watt is used in physics to measure the electrical power, being the result of the multiplication of the electrical voltage (called voltage) and the electrical intensity (called current and measurement in amperes). That said, if you have an older phone model that does not require a lot of power to charge it, you can get a 5-watt charger. On the other hand, if you have a smartphone, iPad, tablet or some type of device that consumes energy, then you need a 10-15 watt solar charger.

The chargers with 15 to 25 watts of electric power are an excellent option if you are not alone in your walk and some other people will also use it. It is also an excellent addition to your camp list if you have more devices that you need to work on during your camping trip.

If you only plan to use this marvel of solar technology to charge your phone, you do not need to choose a more expensive and complicated model with more than 25 watts, which may require an additional battery and inverter, as it is useful for people who want to charge your laptops or air conditioning systems.

However, you should not go to the other extreme and get low wattage chargers because they are less expensive. They can do the job, but they take much longer: 4-5 hours with a 5-watt charger, compared to 2 hours with a 10-watt charger.

But since smartphones are becoming more popular and most hikers own this type of phone, the best solar phone chargers have a high power. They also have batteries that make your device absorb energy at a lower intensity rate (fewer amps).

As a result, you should also be very careful when reading all the details. There is a lack of regulations regarding proper writing, and sometimes it can become really confusing.

So, let’s say that you are watching the power output. You want to choose a solar charger that can charge your smartphone and your friend’s less modern phone. For a smartphone, you need to get a device that has at least a 2.1-amp USB port, while for your friend’s phone you can easily have a 1-amp USB port.

And this is where it gets difficult. Some brands declare that their product has an output power of 2.1 amperes, in reference to the total amperage allowed by your device. In contrast, others mean that each port or at least one port can support that maximum amperage, but you can use both simultaneously.

Therefore, the first device can only charge one device at a time at 2.1 amps, but the second can be used to charge both your smartphone and your friend’s phone at the same time.

Pros and cons of solar chargers

Solar chargers use the sun’s energy to charge your phone. That is why the advantages and disadvantages of solar energy can also be transferred to the devices that use it.


  • Excellent in emergency situations. If you are too far from a power source and need to charge your phone really fast, so you can keep in touch with your family at home or use your hiking app to monitor your trip, then you need your smartphone to work.
  • Solar energy is free. That means that using your charger can be a great addition for home use. Your electricity bills will be lower and you will have your smartphone running at full speed.
  • Sunny weather. If you go on a trip to a place full of sun and daylight, you can be sure to make the most of the energy the sun can provide to charge your phone. Your charger will do the job quickly and you will enjoy the benefits of modern technology on your camping trip.


  • Cloudy weather. If you go to a nice place, but with less sun or in a station with less natural light, then you should reconsider acquiring a solar charger. In fact, this device can help you charge your phone, but instead of hiking and exploring, you will have to wait longer for your phone to charge. Therefore, in this situation, it is advisable to obtain a charger that has a higher power in watts, to make sure that your phone charges faster and you can enjoy your trip.
  • Some chargers can not cope with the needs of your phone. That is why you need to make sure you have double checked the amperage and wattage on the device you decided to buy, so that you can meet the energy needs of your phone. This is also unpleasant if more than one person has to use the charger, as it may prolong their waiting time.
  • Some devices do not fully charge your phone. In this case, you probably have to use the charger several times a day, or simply make amends with the fact that during your trip, your phone will no longer be charged to the maximum.

Types of phone chargers

  • CIGS – This is a flexible panel that can keep it for many days, being quite affordable and lightweight, but not very durable. However, they are quite good at cloudy weather with less sunlight.
  • Monocrystalline – This is the traditional type of solar panel, built to last. However, it does not fold and you can see it as a disadvantage if you are only going to go for a few days. However, most monocrystalline chargers have an improved design and their rigidity is no longer so inconvenient. They are not very efficient in cloudy weather like the CIGS.
  • Polycrystalline – Since these panels are made of multiple silicon crystals, they are not as efficient as monocrystals, made of a single crystal that can make electrons move faster and consume less energy for that. However, these panels are excellent if you want to save money and use them very often.

How to choose a good solar charger

The best solar phone chargers on the market have these characteristics:

  • Integrated batteries – The built-in batteries are excellent if you want to leave the camp and not worry about constantly adjusting your phone. In addition, the battery is also a good addition in emergency situations, when it is absolutely necessary to make a phone call.
  • Automatic restart technology – this feature allows your loader to restart automatically if your activity was interrupted by the brief passage of a cloud. Otherwise, you would have to unplug and re-plug a device that lacks this capacity, which can be considered quite tedious, not to mention that it is not appropriate, if the cloudy moment is lost.
  • Easy configuration – The best panels do not require much time and energy to be set up, and they do not have a ridiculous amount of requirements regarding where they should be placed. Some lower quality chargers may even be impressed if it’s too windy, and that’s not the kind of device you would want for a long trip in bad weather.
  • Light – Make sure you can transport your solar charger easily, but do not sacrifice quality for this function. As such, you can choose a CIGS panel if you want something less heavy.
  • Adaptability – The best products on the market allow you not only to charge your phone, but also other devices. They have one or two USB ports with different amperages to connect your mobile accessories so you can be more efficient and charge everything you need simultaneously.
