Solar Power Bank Buying Guide
Power is a vital element that you will always need to keep your life running through one way or another. You could need it to charge your phone, illuminate the place or even cook.
Unfortunately, it may not be accessible in every situation. What happens on such occasions? Do you sit back and surrender? Probably not the best decision. There is a solution for such problems is a solar power bank.
What Is a Solar Power Bank?
When you hear of the term solar, the first thing to come to your mind is the sun. A solar power bank, as the name suggests, is a gadget used to store power.
Unlike the conventional power banks that you may have previously seen, this model does not get its power from electricity. It has a battery that draws power from sunlight.
The considerable benefit of settling for this choice is bidding goodbye to blackouts. Whether the electricity is running or not, you will always have sufficient energy to keep the relevant items running.
All you have to is charge whenever the sun is high in the sky. The only way to learn more about this machine is to understand how it operates. Only then can you manage to make a good purchasing decision.
How Does A Solar Power Bank Work?
Solar power banks are unique gadgets. The machine features built-in solar panels that trap the solar energy from sunlight. Once this is complete, the power bank converts solar energy into electric energy. The power is stored in the battery. The solar panels are what you can compare to regular chargers.
The batteries come in different capacities depending on your budget and preferences. The batteries store the power until when you need to charge any device.
They have a circuit in charge of controlling the way power flows during charging. The mode of performance is environmentally friendly and also safe. Solar power banks are compact, thus utilizing minimal storage space.
You can employ them during occasions like camping or traveling, and they will undoubtedly serve as expected.
How Long Does It Take to Charge a Solar Power Bank?
Before you understand the duration required to charge a solar power bank, it is imperative to know the appropriate times of the day. Solar energy is one of the most eco-friendly and sustainable modes of generating electricity.
Well, when the sun rises, it keeps moving until when it sets. The shift causes a difference in the amount of solar power during the day. If you want to get the best, it is crucial to charge your solar power bank when it’s a peak moment, and the intensity is high.
However, when charging this machine, you should look out for the light and not the heat. The best time to capture this light is when the sun is just rising, early in the morning. When you place the machine outside when it’s the hottest, you will be exposing the panel to safety risks.
With such provisions, you have to keep up with the sun’s movement; otherwise, it will take more than the required amount of time to charge fully.
You can also charge it indirectly. However, the approach is not as practical as the first option. Well, each solar power bank comes with a different size of solar panel and battery storage capacity.
The distinction is why there isn’t a standard duration for charging these machines. For instance, a battery with a 10,000 mah will need up to around 30 hrs to fully charge. The time increases as the capacity also go higher. However, with more panels, the time would reduce.
If you optimize conditions and charge during the recommended period, you are less likely to use this much time.
What Devices Can I Charge with a Solar Power Bank?
The rapid advancement in technology is one platform that has led to many gadgets; the solar power bank is one of them. More people are becoming aware of environmental consciousness and their carbon footprint.
As technology changes, man has to keep up by using all the available gadgets in the market. Some depend on these machines to keep their life on track. A slight shortage of power may disorient them.
However, with a solar power bank that is fully charged, you can always have a smile on your face. The best part about this machine is it can charge various items, including:
- Mobile phones
- Bluetooth speakers
- GPS systems
The list could be endless. However, check the amount of energy required by these items to ensure it does not exceed what the solar power bank can store.
What Is the Difference Between a Solar Power Bank and Solar Charger?
Solar power banks work by storing energy drawn from sunlight. Once it’s fully charged, you can keep it for when you need to charge any gadget.
However, the machine comes with both benefits and limitations. Solar power banks are reliable as they can always serve you when they have power. They do not rely on anything to work.
However, the machine loses power whether you are using it or not, and you cannot charge all the items you want. It can only keep a few of your items running. If you are charging a phone, it could charge up to around four times and run out of power.
Their counterparts, solar chargers, work differently to charge an array of gadgets that you may have. They provide power by drawing it from the sun. You can power endless items as long as the solar panel is in good shape.
Another benefit is that you have no limitations whatsoever regarding the types of gadgets to charge. Nevertheless, it is also eco-friendly and does not pollute the environment.
Like the power bank, the charger also has cons. The most outstanding one is bulkiness. You require large panels to harvest the solar energy sufficiently.
The smaller panels will take more time as they are slow. Another issue is it can only function when the sun is up. It is imperative to settle for high-quality chargers if you want to achieve your goals.
Features to Look for in Solar Power Banks
When you go shopping, you will encounter different variations of solar power banks. The availability can make the purchasing process a bit overwhelming. It is, therefore, necessary to have some form of guidance to help you.
Below are vital factors that you must consider when choosing this machine. They will determine the efficiency and functionality levels.
There are varying models and brands in the market. The choice of design is up to your preferences and needs. Each design works suitably on specific conditions.
Additional features that accompany this aspect are the shape of the power bank, color, size, and charging cables.
Suppose you want something simple that can fit in the pocket, evaluate the options wisely. If you want something with more extensive panels, the size would be bigger, but the level of efficiency increases.
Another essential factor is the duration required to charge. Assess the size of solar panels as they are responsible for drawing the energy from the sun. The smaller machine might look attractive but is limited to smaller panels that need endless charging before completion.
The capacity of a solar power bank refers to the amount of energy it can carry while fully charges. The storage determines the number and types of gadgets that you can charge.
Since it’s something you can carry around, the solar panels should come with a subtle design that does not require lots of storage space.
Solar Panel Specifications
Solar panels play a massive role in the functioning of the power bank. The dimensions determine the amount of time needed to charge the gadget.
A solar power bank needs to come with accessories like a USB cable to charge the different gadgets. Well, the more the types of cables, the more the options to charge different items.
Multiple USB Ports
The number of ports influences the gadgets you can charge at a given time.
Indicators are crucial since they’re a way of knowing if the machine is charging and when it gets full.
When buying a solar power bank, you have to ensure it can serve you for an extended period. The investment should be worth it.
Water-resistant Vs. Waterproof
Although these two characteristics are different, a solar power bank featuring both of them is much safer. You can use it whenever and wherever without exposing it to damages.
Ensure the device comes with this document. It will shield you from untimely expenses regarding repair or replacement. The more the time allocation, the better.
The information above should enlighten you about the functioning of solar power banks. When buying, take into account the above features if you want to select nothing but the best.
