When people think about using solar energy and integrating it into our daily lives…it can be a daunting task. Sometimes it is easier to look at something a little more manageable.
If we take baby steps – we can use less and less energy. One necessity item we use every day is a cell phone. Most cell phones charge at a manageable rate and capacity.
Solar charger for cell phones
The solar charger consists of a battery and a solar panel. Sunlight is captured via the solar panel. The sunlight is converted into energy and stored in the battery. This energy can then charge the telephone battery. Even when the sun is not shining.
If you use solar energy to charge devices, you naturally need a solar panel. The solar-powered chargers usually have a very small solar panel. Because the panel is small, you usually have to place the charger in the sun for a long time, if you want to have enough power to charge your smartphone. To be able to provide your smartphone with electricity even when the sun is not shining, the solar charger is often combined with a power bank.
The energy that is generated when the sun shines is then stored in the power bank. This way you can also use it afterward and you make sure that your phone does not have to be in the sun anyway. These chargers do not have a 220 V output, but a 5 V output with a USB plug. So you cannot charge large electronic devices, such as laptops. The chargers offer a solution especially if you do not have power outlets in the area for a longer period, such as during a hike through the mountains. Thanks to these chargers you can still power your smartphone.
Options for small scale solar charging
These amazon finds can do or help with the job – here are 2 solutions:
- Solar Charger 24000mAh – this battery solar charging combo will suck up the sun and charge up an attached battery. It has two waterproof, shockproof and dustproof – and 2.1A USBs. It also includes an LED flashlight with 3 modes.
- A single panel charger with 25000mAh battery portable solar phone charger. It had USB outputs – plugins for USB type A cords and a LED flashlight.
To properly charge a smartphone with a solar charger, the capacity of the solar charger must be at least 30 percent higher than the battery capacity of the smartphone. If the capacity of the solar charger is lower than 30%, the phone can only be partially charged.
With a battery capacity of 1500 mAh – you could charge the iPhone 11 to about 50% as it has a battery size of 3,969 mAh. For a full charge – you will want to have one larger than your phone’s battery.
Know what size of battery you are buying to make sure you have enough to charge your phone. Cell phones with a large screen generally have a heavier battery than telephones with a smaller screen. The screen uses the most power.
A practical solution
If you are a lover of nature trips and expect that it will be very difficult to access the electrical outlet, it’s time to get a portable solar panel. It is a simple solution with which you can power various devices.
On the market, you will find small size solar power supplies that are ideal for charging your smartphone. You can also buy devices with larger dimensions and capabilities that will allow you to charge e.g. a laptop or small TV.
If you need big power – look at a portable power station. This station has AC output to 300W continuous and 600W surge. You can charge phones with the 2 USB 2.1A or 2 Quick Charge USB. The battery is big with it’s lithium batteries – it weighs 7.3 pounds and charge a smart phone 25 times without a recharge.
It can be charged with 60W or 100W solar panel, not included; wall outlet; or 12 volt car charger. This station includes a pure sine wave inverter – clean power like utility supplied electricity.
How do Solar Panels work?
The portable solar power set works similarly to solar panels mounted on the roofs of houses. It consists of a photovoltaic surface (whose task is to collect sunlight), a regulator, a battery (storing electricity for later), and a transducer.
The task of the latter element is to adapt the current to the needs of electrical devices. Of course, portable sets have USB inputs or electrical sockets that allow you to finally connect your smartphone or other equipment.
Charging the set is done by exposing it to sunlight so that the battery is charged. During this time, you can connect the selected device or wait for charging until the panel battery is fully charged.
