Foldable Solar Panel Chargers (Portable Power)

Everything runs on energy. It is what keeps the world moving around. The earliest human civilizations were built on their ability to harness the sun’s power to meet their energy needs. The discovery of fossil fuels ignited rapid industrial developments.

Planning on camping? Pack one of these foldable solar panels.

However, the over-dependency on these limited, non-renewable resources is leading to its exhaustion very soon in the future. The world is already facing the problem of energy shortages. On top of that, carbon emissions, nuclear wastes, and other pollutants have become a major environmental concern. In the face of these environmental and energy issues that we are facing today, we have just started to think about alternative energy sources.

Better late than never, solar power technology has gained momentum in the last few decades. The latest innovations in this field seem to promise us long-term solutions to our energy problems.

See our related article on the Best Portable Solar Panels. Similar in size and functionality, these may be a better fit for you.

Be a Part of the Solar Revolution

Solar Panels are the way of harnessing the most abundant source of energy in the world – the sun.  The amount of sunlight that we receive each day amounts to more than 35,000 times the average amount of energy that we use. If we can tap into even a tiny portion of this endless solar energy, we can solve our energy problems once and forever. This is what we call the Solar Revolution.

Solar Panels don’t have to be bulky anymore. Thanks to the latest design innovations, solar panels come in different shapes and sizes. So now you can have a ready-to-go, portable power backup system anywhere you go.

With foldable solar panel chargers, you never have to worry about running out of energy for your electronic devices as long as you are under the sun. Portable solar panels are a great way to escape from the conventional electricity grid without risking a power drain in your electronic devices. From your smartphones to lights and even your electric stove, portable solar panels power it all. As simple as that!

What Should I Look For in a Portable Solar Charger?

Before we dive into the list of the best portable solar panels and discuss their bright and dark sides, you should take note of a few things. These considerations will help you choose the right foldable solar panel that meets your requirements.

Portability

It’s a no-brainer. Portability is the key feature of foldable solar panels. You are often going to be moving with the solar charger. The foldable feature adds to the portability of the charger that you can just pack it up in your backpack and go anywhere.

Weight

You do not want the portable solar panel to add extra weight when you are out hiking. The foldable solar chargers come in different capacities, which determine the overall weight of the panel. The weight consideration depends on the type of traveling you are planning and where you will mount it.

Efficiency

The weight and portability feature directly affects the efficiency of the portable solar panel charger. The solar panel should be lightweight, compact, and take up less space while still providing a reliable power backup to your electronics. The efficiency of solar panels is always dependent on weather conditions.

Reliability

When it comes to your energy needs, reliability is all that matters. You should have the solar panel working when you need it. This is where you want to invest generously in top-quality foldable solar panels that we have tested here. Make sure that the panels are strong enough to withstand extreme weather conditions.

Types of Portable Solar Panels

All the features mentioned above are determined by the types of portable solar panels. There are three types, viz. Monocrystalline, Polycrystalline, and Amorphous.

Monocrystalline solar panels are the most efficient type of portable solar panel chargers. They’re capable of producing a high amount of energy even in bad weather conditions. It is also the most durable type, which justifies its high price tag compared to other solar panels.

Polycrystalline are less expensive than monocrystalline solar panels. However, they are not as powerful as the former.

Amorphous panels are popular for being the least expensive of all. Although it is flexible and comes with multiple installation options, it’s less efficient than the former two as it takes three times more space while producing only the same amount of power.

Considering these factors, we got off the grid and went through in-depth testing of some of the best portable solar panels in the industry. And here we go!
