Understanding A Few Technical Terms Associated with The Solar Device

A little tip here is to gain a bit of knowledge to help you interpret the advertised power and whether this solar charger is the one you’re looking for. That involves Amperage, voltage, and watts! Not a physics student? That’s not a problem!

Think of voltage as the water pressure, current (measured in amps) as the flow rate and resistance (ohms) as the pipe size. Remember the formula: current(amps) is equal to the voltage (think water pressure!) divided by the resistance (or pipe size).

Here’s the working: Current = Voltage/resistance

Watts are a measure of electrical power, which is the voltage multiplied by the current.

Here’s the working: Watts = Voltage x current


Smartphones such as iPhones are extremely power hungry, but the new generation of iPads is slightly better. Usually, you need at least a 7-watt panel to be sure you can charge most smart phones. So when you’re looking for a solar charger for your iPhone, a 4- or 5-watt panel works fine with these devices. It’s suitable for an mp3 player as well.

Unless you’re looking for a solar charger for a more energy-hungry tablet, you can look for a panel with at least 15 watts of power. This is suitable for charging multiple devices at once.

As for AC devices, this would be another category where you’ll need a heavy duty panel starting at 25 watts, a battery and a DC to AC inverter.

We know that some people may be on a smaller budget and they may be considering solar panels with less wattage. Solar panels with less wattage may help you save money, but you will be frustrated when you realize that it’ll take a very long time for it to charge your devices.

It might take more than three hours to fully charge your device. The amount of time taken to fully charge a device can be reduced if you look for higher wattage solar panels.

Output Power

The output power of your device makes a huge difference! Be sure to match your needs to your amps or there could be a difference between charging the device and having a useless dead brick of a phone. Some manufacturers report the total amperage output of the ports combined, while others may report the max amperage of each port.

With this information, you can add them together to get a bigger amperage output. This shows that some panels report 2.1A max,  so when you plug in two devices, the power will be split between the two.

When others that report a 2.1A max, it may really mean that one port provides 2.1 and the other gives you only 1A. The both of them can charge at the same time, but this is one of the specs that you have to pay good attention to when you’re purchasing them, as this may be difficult to tell. If you’re looking for one that charges fast and is powerful, get one with a high wattage.

Different Types of Portable Panels

There are different types of panels that you might want to consider, such as CIGS, Monocrystalline and Polycrystalline.


CIGS is the abbreviated term for Copper, Indium, Gallium and Selenide. These kinds of panels are less costly to manufacture and it is very light in weight.

It’s great for outdoor use, with a very clear Achilles heel: they degrade quickly over time.


The rigid monocrystalline panels are more efficient, compared to the CIGS. However, the monocrystalline panels are heavier and less flexible if you were to compare it to the CIGS panels.

These are actually considered better for backcountry use.


Made up of silicon crystals, just like the monocrystalline panels, both types of cells are made of crystal ingots. Polycrystalline is made up of a growth of multiple crystal ingots. It is 18% efficient, whereas the monocrystalline is 22% efficient. Monocrystalline is more on the pricey side.

We would recommend those small-scale consumers to go for monocrystalline as they may be less concerned about the added cost on a relatively cheap personal-sized solar panel. Polycrystalline panels are considered less efficient when you compare it to monocrystalline panels.

What Are The Important Aspects for Selecting The Right Solar Charger for Your Devices?

When it comes to choosing the right solar charger for your mobile devices, you’ve got to consider the charging performance, the solar panel details, physical characteristics and also the help and support that is available after your purchase. It’s important to know the warranty of your purchased product.

The performance and its charging capability

Be sure to study the charging performance, from its size, type of panel and overall output of the battery for each device. Different devices may have different functionality.

Most devices are charged directly from the battery, but not all of them have the same relationship with the panel. Devices that charge from its battery can also be charged by the panel.


This important aspect is what most backpackers and campers look for when considering the purchase of a solar panel charger. Integrated solar panel or battery devices do not come with a storage system but they’re mostly designed to be compact so you can just put it in your backpack or stuff sack.

Most panels in the market that we’ve seen today come with an integrated pocket which is convenient for people to stash their devices, making it easy to pack up and carry.

Light and portable options are certainly important factors to consider when it comes to buying the right solar panel charger for backpacking. Here’s a tip, even though you may see these solar panel chargers advertised as “emergency use only”, it means “don’t rely on the solar panel.”

So if these “emergency panels” meet your needs, be sure to purchase the solar charger that comes with 2 amp ports, or else it may struggle to charge your power-hungry devices.


In the market, you’ll find most of the panels and chargers to have one or two USB ports, sometimes with different amperage ratings (2.1 amps for a tablet, 1 amp for your phone). It is great for charging a phone, tablet, camera or other devices with a USB charger.

The solar charging market has fully embraced the modern obsession with smartphones and tablets, so if you want to charge something, such as camera batteries that only connect to a wall outlet, the only way to charge it would be to get an inverter.

Some panels may come with grommets to allow them to be easily hung to a backpack, tent or tree, and some come with the capability of daisy-chaining to other panels in order to generate a lot more power.

So before making a decision to purchase your solar panel chargers, it’s best to consider if these features can be found on the device so you can enjoy more convenience when you bring the charger out for your outdoor activities.

Solar Panels

When we’re talking about the quality of the solar panels, we’ll be looking at the efficiency. It is a good indicator of quality and it depends on the type of panel the solar charger uses. In the current market, you’ll be able to find first-generation crystalline silicon and second-generation panels which are better at generating electricity, even in places with low-light conditions.


We understand it’s a quite an investment to get a good solar charger. But if you’re aiming for a good quality solar charger or just in the market browsing for a suitable one, it is important to know how long the warranty of the product is good for and how accessible you are to the customer support team.


A solar power from a portable panel is generally expensive but it can be the solution you need for your power-hungry devices during your outdoor trips and adventures. Keeping a critical eye open to the product reviews and descriptions would be a good idea before coming down to a decision on which is best for you to get.

We hope our reviews provide you with the extra help you need to choose the solar panel chargers for you.

The solar market is vast and growing, so it is best to pay more attention to the details than the looks before purchasing. Here’s our last buying tip: watch out for imposters in the realm of solar chargers and make sure you do your own research before purchasing solar panel chargers online!

4 thoughts on “Best Portable Solar Chargers: The Power of the Sun”

  1. I took the Instapark Mercury 10M Solar Panel Portabl Solar Charger camping, with the intention of trying it out before deploying back to Afghanistan. This little guy is a beast. With the included battery we were able to play music on the iPhone all weekend long without any issues. We could even throw a second phone in there to charge when people needed it. I expected more of a trickle charge, while this thing will charge a phone to 74% in 1 hour. It won’t charge like a wall outlet, but I never expected it too. I am very impressed with this item, and have already ordered a second one for my fiance.

  2. Good to know Andrew! For longer trips I also recommend the Powered Apollo3 8000mAh Power Bank Solar Charger. You can charge 2 of your gadgets and still have enough power to charge other devices. I also find that to “conserve” on the solar charger’s power, I usually charge my gadget and after the battery is “full” that’s the time I use it. If you continue to use your gadget while it is still connected on the power bank, you’ll replete your solar charger in no time.

  3. I have a Power Monkey extreme. It is pricey (bought one for $140) but it is really worth it. I found out that I could get 20% charge on an iPhone 6 plus based on a few hours in the morning. It would have been fine for a long trip if it had not rained. The downside of it is, it’s actually heavy. But if you’re camping with a lot of people, it can really charge your things and is very durable. But for ordinary camping, I would suggest starting with Goal Zero Nomad 7 Solar Panel because it is really lightweight (along with 6 inches 5-in-1 USB adapter to charge things).

  4. Choose the one that’s right for you – that includes making sure you can carry it without straining yourself. The Power Monkey extreme is an excellent product and so is the Goal Zero Nomad 7. Also, take a look at the capacity (mAh) and see if that’s enough for your gadgets. A higher mAh is always preferable especially for long trips.
