  • Powerful charge panels.
  • Water-resistant casing.


  • No built-in loops or attachment hooks.

  • Powers/charges many devices/appliances.
  • Multiple ports.

Solar power banks and portable chargers can come with a lot of jargon that might seem a little confusing at first – especially if you’re not used to the market.

Take a look at this handy guide which will hopefully explain the basics and give you a better idea of what to look out for when choosing the most suitable product for your needs.

What is a Solar Power Bank/Portable Charger?

Forgive me for stating the obvious, but some people can get confused when it comes to the types of chargers available.

A solar power bank will rely on the sun’s rays to convert its photons (light particles) into electricity. I won’t delve too much into the physics, suffice to say you need cloudless, clear skies for the best results.

If it’s just the portable charger (power bank) then it will be a separate battery pack that you charge up and use to boost your devices when required.

Then, you can also get a combination of the two.

In short, you can either purchase solar chargers with an integrated battery – usually housed within a single unit.

Solar panels by themselves, with USB charge ports – usually of a fold-out design. Ideally, you’ll need a battery pack to use in conjunction with these models, as charging your phone directly isn’t always advised and the panels themselves can’t store a charge.

Or simply a power bank that has no solar capabilities, that you charge from a mains socket or in your car before going off grid.

Of course, you can also use a combination of each to suit your purposes.

Perhaps the most important requirement, is how much power a charger is going to provide. It’s going to be pretty useless to you if you purchase a device without the clout to do what is required of it.

You’ll be looking at the Milliamps Hour (mAH) number of the battery – which is an indication of its strength.

The higher the number, the longer the battery will last and how much charge you’ll, therefore, get out of it.

The output of solar panels is rated in watts. Again, the higher the number, the more power it will produce.

The downside to this, of course, is that the higher these numbers, the larger and more expensive the device is likely to be.

In order to identify the capacity right for you, you need to understand what you’re going to be charging. In other words – the specifications of the batteries of your electrical devices.

I could waffle on about this for a long time, but I found the video below to be clear, concise, mercifully short and particularly useful if you’re a total noob.

And if you really want to go back to school, try this explanation:

Size and Weight

Like anything that has the word “portable” attached to it, you would like to believe that it does indeed have the ability to be carried from A to B with ease.

But as mentioned above, the most powerful portable solar chargers are likely to be on the more cumbersome side.

The size and weight of the device will depend on its capacity. And with solar panels alone, the more surface area they have, the more efficient they will be in creating energy.

Then it’s entirely up to you regarding what you want to carry or have the space to pack.

Having said all that, most portable chargers aren’t going to take up that much room and many of the best carry-on backpacks will actually have a dedicated compartment for a power bank anyway.

It’s not like you’re going to be lugging a car battery around on your back, is it?


The very nature of solar powered products means that it’s nearly always going to be used outside.

As a result, the best solar charger power banks will most likely be water resistant, dustproof and shockproof. Some of them may even be fully waterproof.

Even if they claim to be so, I wouldn’t recommend submerging them to find out.

But for the most part, a decent portable charger will be tough and durable to stand the trials and tribulations of being in the great outdoors – particularly useful if you’re keen on adventure sports, hiking, climbing and biking et al.

You’ll find that power banks for mains or internal use aren’t quite so well protected, and it isn’t actively encouraged to have them anywhere near water at all.


Slightly different from the size and weight category, this is how portable the unit actually is.

Does it come with carabiners or eyelets to attach easily to your gear? Do you intend to have it charging in transit? How easily could it hang from a tent or a tree? Does it come with its own case or would it easily fit in one?

All questions you should ask before making a decision in finding the best portable solar charger for cell phones.

Other Features

Aside from doing the job the device was built for, many of these devices come with an array of other bells and whistles to attract your eye.

Flashlights and emergency signals are included in most solar power battery banks – very useful if you get into difficulty, or for rooting around in your tent in the dark.

Foldable solar panels will often come with a dedicated device pocket to store your electronics while they’re on charge.

And certain models will have more than one USB port so you can charge a number of devices at the same time.

Keep a look out for what extra features you might feel could be useful.

Frequently Asked Questions

Some common questions people are likely to have before purchasing a solar power bank or portable charger.

Will it Fit My Phone/Tablet/Laptop/Electronic Massager?

Without a doubt, the most frequent of frequently asked questions is will the charger actually work on my model of phone or other electrical devices? Certainly, for most cells and tablets, the answer is likely to be yes.

Laptops and more powerful electronics require devices capable of producing a higher voltage, so bear that in mind.

My best piece of advice?

Check before you buy – both your device’s requirements and the power output of the charger you’re considering.

Do Solar Power Chargers Really Work?

The short answer is yes. However, a word of caution here – solar powered chargers are meant to be used as a backup option only.

Ensure that battery banks are fully charged before you depart on your trip and don’t rely on solar panels – however strong or efficient they might claim to be.

Of course, it should go without saying that if it’s chucking it down with rain you’re not going to enjoy mega solar power. Strong, uninterrupted sunlight is needed to maximize a charger’s ability.

You never know when the weather will be unaccommodating.

How Does a Solar Panel Convert Sunlight to Electricity?

Again, I could write hundreds of eye-bleeding paragraphs about this, but it would be much easier to simply point you in the direction of the excellent video below.

Can I Take it on an Aircraft?

Now this is a very good question and not to be taken for granted. It all depends on the type and capacity of the battery. If it’s a Li-Ion battery, it must be carried in your hand luggage. The limit airlines permit you to carry is 100W per battery.

This, however, can vary from airline to airline and should be confirmed beforehand.

As a rule of thumb, most low watt batteries/solar power banks/solar panels are perfectly fine – but if you’re packing some serious power you might run into difficulty.


As you might have guessed, there’s lots to think about when it comes to choosing solar power banks and portable chargers – and it can get quite complicated figuring out all the math.

I hope this article has gone some way to assisting your choice and clearing up the most important points, and that you find the best solar power bank for you.

Do let me know in the comments which model you’re considering and why – it’s always nice to hear some feedback.

Happy traveling and charging!
