Have you still remembered the movie clips from The Martian that the hero Mark Watney has used solar panels to keep his vehicle charged? If so, keep reading…

How a Solar Charger Works?

On the most basic level, a portable USB solar charger could convert light energy into electricity and charge an internal Lithium Polymer battery, while leaving it alone in a well-lit area.

Then the LiPo battery can charge your phone or other mobile devices with the stored power. It’s kinda of renewable energy, something that is green and environmentally friendly to make our planet better and better. 

How to be a Best Solar Charger?

While, understanding a little bit about how a portable USB solar charger works will help you to select out one that meets your need best. 

First and Foremost, a portable USB solar charger performs best while leaving alone in direct sunlight on a clear day;

Then, what materials the USB solar panel is made of also matters. Most of USB solar panels, including the tested ones below, are onto the are of the crystalline silicon variety, which is the standard of first generation solar technology featuring highest efficiency rating in creating electricity from sunlight. 

What Points in Selecting a Best Solar Charger?

Or we could say, this are the points onto a portable USB solar charger’s Charging Performance.

The size, the panel type and overall output of the USB solar charger will have a direct relationship with a portable USB solar charger’s charging performance.  

Then, we come to the efficiency, which is a good indicator of quality. It partically depends on the type of panel the USB solar charger users. The first-generation cystalline silicon is known for higher efficiency and better at electricity production, even in low-light conditions. 

Thirdly, we have to consider the USB solar charger’s portability.

If for everyday use, then you’re mostly looking for something isn’t too much larger than the smartphone; at this point, maybe a portable power bank is more suitable. 

If for some kinds of outdoor activities, for example, hiking, backpacking, moutainerring, etc. a larger USB solar charger could be better. 

Lastly, then we should also consider a USB solar charger’s warranty, even though that is not a big investment. Knowing how long the warranty is and how to contact customer support if you have any issues goes a long way.
