Nowadays, as people use mobile phones more frequently, portable chargers have become one of the necessities of users. However, some chargers, such as power banks, also need to be continuously charged, and these chargers are not the same in terms of battery life. So, how to solve the power supply problem of the mobile phone and the charger itself? The best solution may be to use solar energy.

The SolarPaper, a paper-thin solar panel made by Bluesun, is actually the same as other portable USB chargers in terms of working principle. When the user needs to charge the mobile phone, just plug the other end of the mobile phone cable into SolarPaper, so that the mobile phone can be charged. Different from other charging equipment, SolarPaper itself is mainly powered by unlimited economical solar energy.

SolarPaper is very thin, as thin as a piece of paper, making it the most efficient solar panel on the consumer market. It is said that this solar panel can fully charge the iPhone in two hours. (This is about the time required for a wall-mounted charger.) If the user moves the SolarPaper to the shade, then the device will stop charging. SolarPaper is also equipped with an automatic restart function, which means that once the user repositions the device in the light, its charging mode will automatically restart.

Each SolarPaper battery panel can generate 2.5 watts of power, so an iPhone carrying 5 watts of power requires two SolarPapers for charging. Each battery board can be attracted together like a magnet, so that the more battery boards are attracted together, the more electricity is generated. For example, many tablets, including the iPad, have a full power of about 10 watts. Therefore, when charging the iPad, four SolarPaper battery panels are required.

In fact, when users use SolarPaper, they don’t need to go outdoors, of course they must have bright sunlight. Users can even make SolarPaper work next to the windows of the flight cabin. There is no doubt that SolarPaper is definitely the most useful for long-distance travelers, campers and other outdoor adventurers. If the user turns on the camera and GPS positioning mode of the mobile phone, the power consumption at this time will be very large, and the power consumption is also very fast. If these users get lost or need to make an emergency call, they definitely don't want the battery to run out. Therefore, bringing the SolarPaper battery board will definitely solve the big problem.

There are jacks at the corners of each SolarPaper panel, so users can hang solar chargers on their backpacks to charge these solar chargers while walking.
Any device that is charged via USB can be charged using SolarPaper. Some Amazon commentators said that they have used SolarPaper to charge mobile phones and tablets. In addition, they also use SolarPaper to charge devices such as Kindle and GoPro.
