Solar cell phone chargers work with solar panels to recharge cell phones. They may be used while no power source is present, including vehicle batteries or mains electricity–and are often recommended as a means to recharge phones without using up mains power, like electrical cell phone chargers. But how do they work? How do solar cell phone chargers actually work? How much energy do they consume?
Solar Chargers Are Effective To Keep A Device Charged
Like other backup options, solar chargers are an effective way to keep a device charged. They work in the same way as backup air fresheners: they draw on the sun’s energy, which is stored in the silicon semiconductors on the inside of the device, to power up the device and keep it charged. This isn’t all that complicated. The key is a secondary layer of “silicon dioxide” (the same stuff that makes up your car’s interior), which absorbs heat from the sun, but allows heat to pass through, so the solar charger keeps your phone charged even when the sun isn’t out.
Utilize The Same Basic Principle
There are many different types of solar cell phone charger available, depending on what you need it for. Most, of course, utilize the same basic principle: the solar panels are installed on the device and connected to a small, lightweight battery. There are also options where the solar cells are placed on a rigid frame that can be secured to the device. The rigid frame is then connected to the device. This is a slightly more complex solution, but if you want an extremely durable portable solution, this is probably the way to go.
Many devices do better with direct sunlight. An old-school solar cell phone charger, for instance, will do better in direct sunlight than it will with battery backup. If you are planning on storing your phone in a sunny room for a period of time, this might be something to consider. Just make sure that your device can handle it!
Another important factor is the power output. Many solar cell phone chargers are limited by the amount of power that they can store. If you want to leave your device charging, you may have to decide between allowing it to overheat or using a DC converter. A DC converter simply divides the DC input voltage by a percentage and turns it into AC to run your device. If you are in a location where there is only mild to moderate sunlight, then this option might be sufficient.
On the other hand, if you plan on leaving your device in a sunny room or even outdoors, purchasing a DC converter charger will give you much more flexibility. Some devices will even allow you to power them completely off of your solar panels. In this case, if there is no sunlight for an extended period, then you will not have any problems. However, if the sun is constantly shinning, you will have to store the extra power in a back-up battery.
You might think that it would be too difficult to build your own solar panels to power your backpack. However, most of the parts that you need to build these are found already. In fact, if you buy the kit that contains the batteries and solar cells, then you can even put the entire thing together in a weekend. Although it would be more expensive to buy a complete kit, it may be a better investment if you plan on charging your cell phones as well as using the solar chargers to power other things as well.
