Although the continuous storms of the past few weeks have not allowed the sun to shine brightly, I have decided to get a solar charger. There’s a Whole World in the Amazon, a Good Part of Them Is Working Battery attached to small solar panels.
My goal was to avoid: I just wanted a solar panel attached to the phone, See what happened and what possible use scenarios emerged. I searched with my team for the cheapest one and this is what I found.
a solar panel and a usb, nothing else
As I told you, if you search for “solar charger on Amazon” the most common thing you’ll find is power banks that have solar panels attached to them. It’s very simple: just a solar panel with a usb cable, Here’s one of its main drawbacks, as most of my electronic devices connect via USB-C. The plates have IP67 certification for water resistance (this protocol can withstand submersion up to 1 meter, although I do not recommend getting this device wet).
The main limitation of this charger is that it can charge at 5W in the best scenario
Another limitation of this product is its output: It has only 5W of power, It powers off all of my portable Bluetooth speakers, almost any type of LED light I want to use as a prop for reading a book, or powering any device that needs a certain amount of power. is seeking.
Its main function is to charge devices, so let’s talk about how it works. This solar panel has a USB port, so it is incompatible with fast charging systems of existing phones. In fact, if we add that I had to use a USB-A cable on a phone with a 5,000mAh battery (Samsung Galaxy S23 Ultra), you can imagine the charging figures.
This mobile gets charged in an hour at 45W. with solar charger Could not load it completely, This is because the ultimate power is 5W under ideal conditions of full incidence of continuous sunlight. The reality is that applications like the Electron showed it barely reached 1W with the solar panel in the window, so it would need practically a whole day to charge. Yes, if we are not in a hurry, we can get a small percentage of autonomy, but with the large batteries that currently exist, charging between 1 and 5W is not possible.
Although it works with ambient light, we need direct sunlight if we want charging power. This requires us to be somewhat careful with the electronic devices we are charging, most are enemies of the sun
The other thing to note is that, as you’ll see in the picture, I had to manage to keep the charger in a window and secure the phone on a table so that the sun doesn’t hit it directly. this charger “Don’t Need” The Sun To Hit It HardIn my case it has worked even with ambient light. However, if it is sometimes difficult to reach 5W even with sunlight, it is not possible to charge any device with ambient light.
Despite this, This device is very portable, In fact, it comes with a carbine that allows us to hang it from any backpack. It seems to me an ideal complement, as can be seen in the image, to keep the phone or portable battery safe in a backpack and feed it slowly.
A trip to the mountains, a day at the beach… As a solution to get some energy while enjoying your free time, it’s a perfect complement to summer. It has significant limitations on charging time, as we have seen, but it is a great option if we do not want to depend on power banks and want to use clean energy.
