How To Choose The Best Solar Charger For Backpacking

Amperage, Wattage, and Voltage

It’s important that you have the idea about all the three things mentioned above. The clearer your conception is of these factors, the easier you can choose a good solar charger for yourself.

Firstly, Amperage is the amount of electricity that flows in a second and is measured in amps. A charger with a high amperage value will charge your device much faster than another charger with a relatively lower amperage value.

However, if the device you will be charging has a low charging potential, then using a high-amperage solar charger won’t have any effect. Therefore, if the devices you’ll be charging have high amp potential, it’s best for you to buy solar chargers with high values of amperage.

 

Voltage is basically the amount of electrical energy produced from the chemical energy stored in the battery. It’s measured in Volts (V). Generally, mobile phones take 5 volts energy while charging from a USB cable. Using a charger with the higher voltage is dangerous as it can cause too much to heat to develop and damage your phone.

On the bright side, all the solar chargers for USB cables are manufactured to provide 5 volts. So, you don’t have to care about the voltage of the solar charger you will be purchasing!

 

Wattage is the power produced by the solar charger. It’s the product of the voltage and amperage of the charger. For example, if your charger produces 5 volts and 2 amps of electricity, its wattage will be 5X2=10W. For normal mobile phones, a solar charger with 20W would be a very good choice.

Small devices have a lower energy requirement, so chargers with less wattage will be enough. For tablets and iPads, less wattage will work. But they will take too long to charge fully. So, if you’re also considering to charge your tablets, even laptops, then it’s better if you pick a charger with a high wattage.

Wattage also determines how fast your device will charge. A higher wattage means your charger has a higher amp rating (considering voltage is always 5V), so your device receives more electricity at a certain time. Thus, it’ll charge faster. A high wattage solar charger will also recharge faster than a low wattage one.

Wattage is a very important factor you MUST consider. You’ll be going long distances, and sometimes you might not get enough sunlight, and having a high wattage solar charger will be very helpful, because, it can store a lot of charges, and it can also charge your devices rapidly and completely.

 

Charging Efficiency

Charging efficiency means how much solar energy the solar panels can convert into electrical energy, which is used to charge your devices. A very good quality solar charger will have an efficiency percentage of 21%.

The best solar charger for backpacking should have a high charging efficiency, it should recharge quickly and store more amount of electricity while it’s in the Sun. Now, as it’ll have a larger power reserve, it can charge your devices fully in a shorter period of time, compared to a charger with a lower charging efficiency.

Therefore, while purchasing a solar charger, you should check its efficiency. In general, it’s written on the solar charger. The higher the efficiency of your solar charger, the better it is for serving your purpose.

 

Types of Solar Panels

There are mainly three kinds of solar panels used in the solar chargers. Each has their own specialty and advantages.

 1. Monocrystalline

These solar panels are made of minute single crystal blocks. Monocrystalline solar panels are much more efficient compared to other kinds of solar panels. They lose the minimum amount of energy and also recharge faster.

However, these solar panels are relatively heavier and harder to carry around. Although it can be a bit costly to manufacture these, monocrystalline solar panels are more durable than the other solar panels.

2. Polycrystalline

Polycrystalline solar panels have more than one small crystal block in each photovoltaic cell. They take some time to charge and are a bit less efficient than the monocrystalline ones.

On the other hand, these solar panels are easier to carry around. They are also easier to manufacture, and relatively inexpensive.

3. CIGS

CIGS is the tiniest, but the most bendable solar panels. They can be made from thin layers of ductile metals, or even from fabric! Their ease of flexibility helps them to turn into any shape and squeeze in anywhere, to do their job.

But since metals or fabric are used, CIGS will easily wear away and are not long-lasting at all. They also have a low efficiency, so they can’t be relied on to fully charge mobile phones. However, for charging small devices requiring less power, CIGS can be an easy option since it’s very cheap to manufacture too.

You should be concerned about the solar panels in your charger when you buy it. Monocrystalline panels are better at functioning but carrying can be cumbersome. Polycrystalline ones are less efficient but economical.

Also, it’s important for you to know about the surface area of the solar panel. Your solar panel should have a large surface area. More light will strike a large surface area, so the photovoltaic cells will convert more light energy into electrical energy. Hence, your charger will have a larger power reserve.

 

External Battery

External batteries for solar chargers are quite important. Some solar chargers have an integrated battery which gives more ways to charge. External batteries are for those chargers which don’t already have an internal battery.

External batteries can be quite advantageous. In the Sun, the solar charger can be used to charge the battery entirely. The battery will store the power to be used for charging later. For instance, you can use the battery to charge your phone at night.

You can also choose the perfect battery to charge your phone, with the required wattage and specifications. As a result, you can charge the battery at daytime, then, at night you can charge your phone much more speedily and efficiently. So, using external batteries gives you a more efficient way to charge your devices using solar power.

The only drawback that might arise from using external batteries though, is the extra weight it’ll add to your backpack. You will be carrying a lot of stuff anyway, and an addition of another battery is the last thing you want.

However, by thinking smart you can manage a way to carry an external battery without putting too much load on the backpack. You can pick a small solar charger which has less power. This will charge up the battery which has a high wattage, and the battery will charge your phones/tablets. Batteries are more useful in charging up your devices. So, charging the battery instead of your devices using the solar charger is a smarter and better method.

 

Output Connections

You should always check the output connections of your solar charger. Almost solar chargers have USB ports, and you’ll connect your device using a USB cable. You should make sure you can charge your devices directly from the solar charger and that the solar charger has the appropriate USB port for your devices.

Some solar chargers have multiple output connections, which means you can charge more than one devices together. As good as that sounds, there is a problem that you’ll face when you use this kind of solar chargers. The total amperage value of the charger will be divided among the connections. This will make charging very slow and inefficient. Some devices might not even start charging at low amperage values.

Hence, while purchasing a solar charger, you should check the output connection provided, and purchase only if they serve your needs. You can go for chargers with multiple charging options, but you should make sure it has a high amp rating. Otherwise, there are chargers which have different amp ratings for different ports, but they’re pretty expensive.

 

Size and Weight

Size and weight are very important factors which must be taken into account. Although a bigger size of solar charger means more power can be stored, it can actually make your journey more tiring and arduous. So, selecting the perfect weight and size of a solar charger is vital.

The effect the charger will have on the backpack also depends on how packed the backpack is. If it’s already stashed with other stuff, then solar charger you buy should be the lightest one possible. However, the lightest ones aren’t very powerful.

It’s not really possible to make the solar chargers small and powerful at the same time. That’s because the solar panels need a large surface area to provide more power. A good number of solar panels are needed too, and more solar panels take more space, increasing the size.

Therefore, a solar charger of such weight should be chosen, which won’t trouble you while you, for example, trek a hill or climb a mountain, and will also provide you enough power to charge your devices appropriately. We’ve presented you with the most efficient but lightweight ones to help you choose easily.

 

Ease of Use

Surprisingly enough, for such a complex mechanism taking place inside, using solar chargers is a piece of cake! Your device will be connected to the solar charger and the charger will be facing towards the Sun. As the light strikes the charger, the light energy is converted into electrical energy by the solar cells present in the solar panel. This electrical energy is used to charge your battery. YES, IT IS THIS SIMPLE!

In contrast to that, we can also use external batteries as mentioned before, and it’s nothing tough either! The only extra additional thing you need to do is that instead of charging the phone, you charge the battery. And, then the battery charges your phone- this method is more efficient.

Solar chargers also have microchips inside. These are programmed in a way so that these can make amends during charging, and ensure electrical safety as well as efficiency.

The position of the solar panels is a key factor. The Sun is at different positions in our sky at different times of the day. And so, you can position the solar panels at different angles, so that they receive the maximum amount of light and yield maximum power.

You don’t have to carry out any kind of complicated tasks while using a solar charger.  That’s what makes solar chargers so convenient and useful.

 

Versatility

Nowadays, a lot of people carry multiple devices around with them. Laptops, iPads, iPods and obviously mobile phones. So, if you’re one of them too, you have to make sure your solar charger is handy and can multitask.

Most solar chargers have several USB ports of different sizes (mini, micro) so that it can charge multiple devices at the same time. Some companies facilitate different amperage values for each USB port. This is extremely efficient and saves a lot of time.

If you’re using a port, designed to charge mobile phones fast, to charge a tablet it will undoubtedly take a very long time. Rather, if you have a port with higher amp rating, you can charge your tablet a lot faster. So, versatility is a significant factor, especially for those who carry a lot of devices and are going on long trips.
