solar power banks

Have you ever experienced getting ready for work in the morning, and then as you step outside and prepare to leave, you find out that your phone’s battery is only at 1%? Forgot to charge it the night before, huh? Don’t worry, it happens to the best of us. While some people can easily charge their phones in their car, not everyone has their own vehicle. How about at work? Well, most companies don’t allow the use of mobile phones during work hours. Want to know how to solve this problem? It’s simple: use a power bank!

Did you know that the first power bank was invented in 2001 by a bunch of college students? This power bank was first presented at the Las Vegas International Consumer Electronics Show. It consisted of Double A (AA) batteries and a piece of control circuit connected together. It looks nothing like the ones that we know and use now. In around 2006 to 2009, more companies became more interested in creating portable charging devices for mobile phones.

Fast forward to 2020 where people are more aware of the negative effects of the excessive usage of electricity, and most of them now opt to use solar power banks instead of the conventional ones. But how different is one from the other? Read on and we’ll tell you everything you need to know about solar power banks: their uses, advantages, and disadvantages.

What Is a Solar Power Bank?

A solar power bank is a compact and portable charging device that utilizes the sun’s energy as an alternative to electricity generated from fossil fuels and gases. Conventional power banks work by plugging it into an electrical power source, which charges its batteries. Once fully charged, it can then store enough power to charge other portable devices such as mobile phones or tablets. A solar power bank, on the other hand, works by absorbing solar energy through the use of PV or photovoltaic cells, converting the said energy to electricity, and then storing it in a battery.

Most solar power banks are so small and compact that it can fit into a person’s pocket, but don’t underestimate its size and capabilities. Not only is it easy to carry, it’s also not as heavy as other power banks. And since this device relies on solar energy, it doesn’t require charging adapters or electric outlets. It just needs a few hours of sun exposure and it can hold up electricity that can power up and recharge your cellphone’s battery to its full capacity. Smartphones have been a large part of our lives for a long time now thanks to their multi-functionality. What better way to recharge your gadgets than to use a solar powered charger?

How to Choose a Solar Power Bank

With so many brands and types of solar power banks being sold in the market today, choosing one over the others is no mean feat. This is why you have to be wise about your choice before clicking on that checkout button. Let us make things easier for you by providing some pointers on what to look for before purchasing or considering purchasing this product.


There’s no denying that most of the time, we look for the brand name of a product first before checking its value and true purpose. There’s nothing wrong with that since most of the popular brands we know would not have made it big if the products they sell are of poor quality. So if you’re pretty particular with brands, then some of the famous solar power bank brands to look out for are Feelle, Hiluckey, Beartwo, Goertek, and Hobest.

USB ports

Let’s face it, when we go out of town or on a vacation, we usually bring one or more gadgets with us. We often keep not just mobile phones but also tablets, digital cameras, or portable gaming consoles on our person. In this case, it is best to get a solar charger with multiple USB ports to maximize its charge. If it has two ports, then surely it has more power to fully recharge more than one device.

Power output

This refers to the amount of power or voltage that the power bank can provide to recharge an electronic device. It pays to know the power output to make sure that its voltage is compatible with your phone or tablet to fully recharge it. It will also help in finding out if the solar powered charger will meet the requirements that your phone needs to sustain its juice. 

Size of the bank

This simply refers to the actual size of the solar charge bank. For people who don’t like carrying a large bag or purse all the time, there are power banks that are the size of a conventional smartphone. But for those who often go on adventures or are always in the great outdoors, then there are a few larger choices that can easily be slipped into your backpack.


The capacity is clearly one of the most important aspects to look for when purchasing a power bank. This factor is what separates one item from the other. The capacity is identified as the mAh or milliampere per hour. What it means is that the higher the milliampere per hour, the more power it will produce to fully recharge your devices.


Since a solar power bank is often used outdoors, it is advised to choose one that’s made with durable materials to make sure it can stand the test of time or wear and tear. Most solar banks are waterproof, so it should survive harsh weather like heavy rainfall or snow. Only get those that are made of excellent quality materials so that you can get your money’s worth. 

Heating capacity

It refers to how hot the power bank becomes when it gets charged. Since this one uses energy from the sun, then you can expect it to heat up during sun charging hours. Check if the charger has the capacity to overheat, which is usually when it gets too hot to the touch.

Pros and Cons of Solar Power Banks

Some things are just too good to be true, and this can also be said about solar power banks. Every item or product has two sides: its pros and cons. Here we have listed some of the advantages and disadvantages of solar chargers to help you decide on whether you’d like to get one or not.


  • Its main purpose as a backup charging system

Plain and simple. A solar power bank is mainly used as a backup power source. When you’re out and about, you can’t always find a power outlet where you can plug your phone in, and this is when a solar charger is most helpful.

  • Low to no maintenance cost

Since solar charging relies on solar energy, which is infinitely free, it means that it costs almost absolutely nothing to maintain and keep the charger working.

  • Clean and sustainable power source

With the utilization of solar energy, we are limiting the usage of electric power that’s generated from fossil fuels and harmful gasses that slowly inflicts irreversible damage to our ecosystems and ozone layer. Not only is solar power absolutely clean, it’s completely renewable and sustainable as well.

  • Expected return on investment

Solar power banks are made for the long haul. Unlike consuming electric power that results to constant increase on electric utility bills, a solar powered device does not require any payment during use. You’ll only have to purchase it once and you can utilize it all you want with no additional cost.


  • Charging time can suffer during bad or extremely harsh weather conditions

Since electricity often gets cut off during a storm or heavy snowfall, most people rely on solar power banks. Unfortunately, during these times, it’s almost impossible to get the power banks to charge when the sun is not out or completely hidden.

  • There’s no chance of getting solar charge overnight

Unlike conventional power banks that you can plug in and leave to charge while you sleep, solar chargers have to stay exposed to the sun for long hours to get fully charged.


Whether you’re someone who has fun doing outdoor activities or just somebody who is always busy and has no time for other things, both can benefit from a durable and reliable solar power bank to keep your gadgets or mobile devices fully juiced up to serve your needs. If you’re planning to live off the grid but still want to be updated with what’s happening elsewhere, then you can get the most out of a solar charger.

Aside from the great benefits we can get out of solar power banks, it is nice to know that the environment can benefit from it as well. If we continue to limit the usage of greenhouse gases and fossil fuels to power up our electronic devices, we can definitely see a brighter future to look forward to. A future that’s clean and away from the dangers of climate change and extreme changes in weather conditions.

So if you’re up for all of that, then take that first step to living green by considering purchasing a solar charger today. It’s definitely a small step, but we all need these tiny first steps so that we can reach our goal. And that goal is to keep our environment alive while we strive to survive.
