If you are planning a camping trip, trekking or simply want to reduce power consumption in your house, a solar power bank is your go-to gadget. As the name suggests, a solar power bank is a solar-powered gadget meant for charging electrical devices such as laptops, tablets, and phones. Solar power banks get their power from direct sunlight through solar panels that are built into the face of the device.

We have compiled a review of some of the best solar power banks on the market today based on features such as capacity, output, ports, etc. These and a few other factors can and should influence the power bank you buy. We will discuss these features in more detail in the buying guide at the end of this article.

Moreover, it is highly water resistant, dust-resistant and shockproof making it ideal for all manner of outings.

How Do Solar Power Banks Work?

For those of us who are near-constantly on the move – for the travellers, the modern-day nomads, the business commuters and the wanderers – we know just how important it is to have a reliable, durable, dependable access to power at all times. Not that we need to be online at all times (you may well be planning a camping trip precisely in order to get away from the constant connectivity of social media), regardless, it is essential that you have a means of charging your devices should emergency arise. Then again, maybe you do just want to know you’re connected, to know that no matter how far you travel, or how long it is until you next have access to a wall-plug, you will always be able to power your devices.

The most affordable and straight-forward means of doing so is to carry a power bank with you. Problem is that with conventional power banks you need to charge them from time-to-time, too! No use when you’re out in the wilderness for days on end, or midway through a trans-Atlantic flight. Thankfully, solar power banks are never more than a beam of sunshine away from a source of power, and as such, can keep you charged always. But you’re probably still left asking: are they reliable? Do they really work? And if so, how do they work? Well, let us tell you.

As you’ll know if you’ve ever used a portable power bank before, they are essentially handheld batteries with a store of charged energy. Each unit typically comes with at least one, if not multiple USB ports for you to plug your device into. When the power bank is turned on and a device plugged in, your device will begin charging by draining the power bank’s resource of electrical charge. Depending on the size and capabilities of your power bank, you may be able to charge your device several times over, charge several devices at once, or even power larger devices than smartphones, such as laptops.

The difference with solar power banks is that you never need to plug them in to charge them. Instead, solar power banks come with solar panels built in: either into their frame, or as additional, fold-out components of the overall design. Either way, they work the same. Solar panels on power banks are built up of many individual solar cells, comprised of layers of thin films of polycrystalline or monocrystalline silicon. The silicon has one especially unique property: when exposed to direct sunlight, it undergoes a chemical and physical reaction, during which a movement of electrons between silicon layers generates volts of electricity. This is called the ‘photovoltaic effect.’ in Simpler terms, the solar panels on solar power banks convert sunlight into electricity. This electricity is then fed directly into the power bank, where it is stored until needed.

And that’s about it. Much simpler than it looks. Many portable solar power banks come with additional features such as in-built torches (perfect for camping at night), wireless charging, compasses, karabiners and more. All are built of waterproof and weatherproof, durable materials.

Pros and Cons of Solar Power Banks

As with all complex technology, or in fact anything you’re looking to spend your hard-earned cash on, it’s worth taking a moment to examine the positives and negatives associated with the product. Let’s take a look at the pros and cons of solar power banks.

Pros:

  1. Free electricity! With solar power comes one particularly lucrative perk: zero additional costs to your energy bill. If you’re looking to save a bit of cash on your monthly bills, and yet still want to keep your devices fully-charged on the go, then a solar power bank is most definitely your best bet.
  2. Green energy. If you’re not only budget-conscious but environmentally-conscious, you’ll know just how important it is to do every little thing we can to help protect and preserve (if not heal) our world. Switching to green, renewable energy sources like solar power is the best, most affordable means of giving the earth a helping hand.
  3. Emergency ready. Unlike conventional grid-charged power banks, which could run out of juice and thus leave you stranded right when you need them most, solar power banks will never put you in that situation. Provided you expose them to sunlight on a regular basis, and for the requisite amount of time, you’ll always have a free source of power when you need it most.
  4. Durable. Built to withstand all but the worst and most extreme of weather conditions, your solar power bank’s solar panel will continue generating electricity no matter what (provided there’s some sunlight). Moreover, the unit itself will survive any amount of falls, knocks, dust and debris, since they’re designed for the outdoorsy type.
  5. Versatile. Gone are the days of single-port power banks. With the products on our list, you can charge sometimes up to 5 devices at once, or even charge large devices such as laptops, all using only the power of the sun. Find yourself in an overcast area, though, or happen to be stopping by a conventional power source and you’ll find that many of these banks can also be charged via a wall-plug. Better still, many of the solar power banks on the market have super handy additional features, such as in-built torches and wireless charging, making them the ideal camping, hiking, and vacation accessory.

Cons:

  1. Variable charging rates. One of the few downsides about solar power banks you’re bound to notice is the variable rate of charge given to your devices. Depending on the amount of sunlight the unit is receiving (or has received), as well as the number of devices you have plugged in to charge at once, the rate of charge may be considerably slower than that which you would experience at home.
  2. Sunlight dependent. As with anything solar-powered, it’s worth remembering that unless your solar power bank receives consistent and strong sunlight during the daylight hours, it will not have a chance to fully charge, and thus will not meet your highest expectations when you attempt to power your devices later on.
  3. Expensive. Not that they all are (some solar power banks are super affordable), but those on the upper-end of the scale can start to become really quite expensive. (At least they’ll save you some money on energy bills in the future!)
  4. Bulky. Handy though they may be, solar power banks (like all power banks, to be honest) can be a bit bulky and clumsy looking, and as such can be cumbersome when packing. Still, needs must!

Buyer’s Guide: Tips for Choosing Solar Chargers

There are several vital factors and options to consider when choosing a solar power bank.

Capacity

This is perhaps the most important quality to consider when getting a solar power bank that you can take anywhere with you. This is because the capacity indicates how many times you can charge your devices on a single charge. Always opt for a solar charger with a higher capacity rating because it will guarantee power for your devices for longer. This is especially advisable on longer outdoor trips. Though lower capacity be compensated by faster charging times and improved solar energy conversion rates.

Power bank Input

Input rating indicates how long it will take the solar power bank to fully charge. Additional solar panels mean extra panel surface area is exposed to the sun during charging, hence your power bank will charge faster. A single solar panel on the other hand takes longer to charge, which is not good if you are camping.

Power output

Choosing a charger with a lower power output is actually quite a common mistake which will, unfortunately, end up draining your cell phone or gadget battery as it has a higher capacity than the charger. Go for a solar power bank that has a higher input than your smartphone.

Note that a portable solar battery pack hardly ever has enough power to charge a device like a laptop but will do just fine for a tablet, camera, cell phone, or smartphone. For a laptop, you need a charger with a power rating between 12v to 24v.

Quality vs pricing

Sometimes, lower pricing usually means lower quality. This is especially the case if you buy your products from an unknown brand or a brand with a questionable origin, where this often results in problems such as device overload. If this happens, your devices could get damaged.

When it comes to reputable brands such as those discussed in this article, a low price tag might not necessarily mean the products are of poor quality. However, overall, the more you pay for a solar charger, the higher performance you get from your solar power bank.

That said if you don’t need features such as multiple device charging, wireless charging, or you use a feature phone and not a smartphone, you can buy a solar charging bank that is a bit more pared down in features.

Remember to check the other buying criteria such as output.

Weight and Size

How much charge do you need? Do you need an unlimited charge or just enough power for one-off charging? Power banks tend to weigh more when they have a large storage capacity because the battery is heaver.

Solar power banks with more panels can also be made heavier by the attachments used to join them together. If you don’t need to mount your panels on your gear so that you charge on the go, consider if you can leave some of these attachments behind.

Warranty Coverage

A great solar power bank should serve you for a long time. This means that the power ban should be sturdy enough to last for years. When you buy a lower quality power bank, you will end up needing a new one probably sooner than you are ready to spend on another one.

Most of the power banks discussed in this article offer a 1 year to 1.5-year warranty which is enough peace of mind when you are regularly outdoors especially in bad weather conditions.

Final verdict

Taking into account all these factors but with a special regard to durability, efficiency of the solar panel and price accessibility we have got to go with the Blavor Solar Power Bank. Though it may have a lower battery capacity than other featured models it is one of the most efficient and versatile power banks on the market today.

FAQs

How can I tell if a solar power bank is compatible with my phone, tablet, or gadget?

Most solar-powered chargers are designed to charge the majority of smartphones, tablets, and gadgets like cameras. The fact that most solar power banks come with USB output ports also means that they can work with most devices.
In fact, you probably don’t even need to buy a usb cable to use with your solar power bank because you already have the USB cable that came with your phone charger.

How do you fully charge a solar power bank?

Solar gadgets, including solar power banks, need exposure to sunlight in order to fully charge. To avoid disappointments during your trip, it is recommended to charge your solar bank fully before you set out. This will ensure that your power ban has enough capacity to charge your devices.

What is solar power bank efficiency?

There are two factors to consider when we talk about solar power bank efficiency.
One, the efficiency of the solar panel charger. Two, the efficiency of the storage batteries
Solar panel efficiency is a rating used to measure how well panels are capturing sunlight. For example, if a solar panel only converts 40% of the sun hitting it into stored energy, then the rating will be 40% efficiency.

What is the difference between input and output charge?

Input is the energy going into the solar bank especially when you are charging it through the wall socket. Solar chargers use Type C USB or MicroUSB for power input. Output is the measure of energy going out of the solar bank into the device you are charging.
