How to Choose the Best Solar Backpack

Solar backpack, with its inbuilt solar panels, is the best idea to have a sufficient power source in remote areas. However, there are various factors to consider while shopping for solar backpacks. Here we have mentioned some of the essential features that have to be taken into account to choose the right one, as per your requirement.

1. Bag Size & Capacity:

The size or capacity of a backpack will let you know how much stuff you can place into the bag before it tears/rip out. Simply, it is the maximum volume of the bag and is usually measured in liters (L). Based on the bag’s dimensions, most companies calculate its capacity/size, while others offer extra side pouches or compartments.

The general size/capacity of a backpack will range from 15L – 25L, which offers sufficient space to store and carry some books, laptop, clothes, water bottle, and other miscellaneous items. However, the size is not huge and provides the capacity to easily carry your daily essentials.

We notice smaller backpacks that range from 8L – 10L, which can handle small loads and are a perfect option for athletes, like cyclists or those having short hiking excursions. While long-distance hiking requires backpacks that range from 30L – 100L, which can handle huge loads or a large set of equipment, such as camping supplies. Make sure to pick a backpack of at least 60L capacity while hiking for more days.

2. Wattage:

The main purpose of this solar backpack is to charge a smartphone and other electronic devices whenever you need them. For this, a solar backpack should have a decent solar panel. Different solar panels charge the phone at different speeds based on their performance ratings, which is determined by the wattage (W).

Most smartphones will charge at 5V, and to produce this power, you need 5-watt (or more) solar panels. The range of solar panels in most solar backpacks will be 5W – 12W. Since a solar panel with less than 5W will take a longer time to charge the device. So, avoid picking it as it is not much useful. While it is a bit rare to see a bag with a solar panel higher than 12W.

Keep in mind that a solar panel with higher wattages won’t mean faster charging, yet it helps you on cloudy days when there is limited sunlight.

3. Charging Time:

One has to consider the charging time needed for their solar backpack before making its purchase. Usually, high-capacity solar panels need more charging time and thereby provides the most substantial and prolonged charge. Alternatively, low-capacity panels will charge faster and also quickly runs out of power/charge.

Expensive or premium solar backpacks will fully charge your smartphone within 2 – 3 hours of sunlight. On the other hand, cheaper models with inadequate solar panel range will charge the phone in 5 – 6 hours (or more). Although, the condition of sunlight (normal or cloudy or sunny) observed by the panel will make a lot of difference, yet most solar panels will quickly charge the devices compared to other models.

4. Device Voltage and Usage:

Different solar-powered backpacks come with different specifications, in which some mentions specific voltage that is lower or higher than your device requirement. For knowing its right voltage, you have to check your most-used devices like tablets or smartphones. Then check if the battery pack in the backpack will meet their requirement. If the gadgets are USB powered, then they need a 5V charger.

Do you use this solar bag daily? Then keep in mind that most battery packs aren’t capable to charge and discharge. If any electronic device requires immediate charging, then you must have any of these two options. It ensures you have stored sufficient power in the battery pack (or) the solar-powered backpack allowing direct charging (directly connect a cable to the solar panel).

Direct charging is quite useful whenever the battery runs out of power and you have to charge directly from the solar panel (which observes, collects and converts solar power). Yet, one has to find a solar backpack with an appropriate connector that allows direct DC charging of devices/gadgets without damaging them.

5. Solar and Battery Power Capacity:

The solar backpack is capable to accommodate various devices or a minimum number of gadgets and also as tool backpack you carry with you on a trip. Mostly, pick a model with a high-capacity solar panel that charge and produce a decent amount of electricity in a short time.

Check to know the full charge of the device in mAh (milliamp hours) and compare if the backpack battery’s capacity match or exceed that value. Mostly, experts suggest picking a battery pack with 5% – 10% more power capacity. Also, ensure the battery pack initially gets fully charged to make sure it charges other devices fully.

Generally, lithium-ion batteries are quite strong, durable, and last longer, which makes them the most preferred option. Apart from that, one can find a solar backpack that stores the remaining charge into the battery.

6. Removable Solar Panels:

Some solar backpack models offer removable solar panels rather than sewn-in solar panel models. This removable solar panel will make it easy to remove and place the panel in direct sunlight while using the rest of the backpack (as a normal one).

However, detachable solar panels make it easy to grab the solar power required for your devices. It is especially useful while spending most of the time indoors (i.e., away from sunlight). If you are a hiker, adventurer, or camper, who spend most of the time outdoors using the backpack, then it doesn’t matter much.

At times, the position of the backpack won’t let the solar panel catch the sunlight, particularly while walking around. Want to maximize the power produced by solar panels, then ensure it should be detachable to adjust the panel position to make it exposed to the sun for its proper functioning.

7. Charging Compatibility:

Most chargers are designed only for smaller devices. While a few solar backpacks give sufficient energy to maintain the smartphone well charged, which is perfect when using it only in emergencies. Other solar backpacks provide enough power to charge electronic gadgets like smartphones, DSLR camera, GPS unit, and laptop. It is a perfect option for hiking photographers, and great when spending efficient time in the wild and require to keep the device running.

8. Weight:

Are you planning to go on longer hikes or overnight treks? Then it is a must to consider the weight of your backpack. A solar backpack with a slightly heavier weight is perfect for day hikes, as it let you carry food, water, and less gear. The weight of the backpack becomes crucial whenever the hiking distance increases. So, purchase the lightest backpack if the extra weight is replaced for more volume or solar power.

9. Durability & Weatherproofing:

Sometimes, we notice a few so-called the best solar backpacks will face issues with their durability, and longevity (lifespan). For instance, one may notice the battery of their backpack dies after using it for a few months (or) experience problems with the USB port connections. All these electronic issues are quite common while using cheaper solar backpacks.

When it comes to durability, pick a solar backpack made of top-notch materials and offers weatherproofing that sustain any external conditions and works well. It should be waterproof without leaving your digital devices wet/damp.

10. Wall Outlet Charging:

One has to place the solar-powered backpack outside, where there are perfect sunlight conditions for several hours a day to grab the essential energy used to charge your electronic devices. Practically, it won’t happen always due to climatic conditions (like rainy or cloudy days).

So, it is always better to purchase a solar pack with a power bank that comes with AC outlet charging capabilities. This means the power bank gets charged from either a regular wall AC outlet or solar panels. However, most people use solar energy from their solar backpack as a top-up to keep the power up (charge) the power bank while walking around.

11. Pockets, Wires, Sockets, & Plugs:

It is essential to select a solar-powered backpack that has several plugs and cables to charge and accommodate various electronic devices. Also, it is good to check for a backpack with several pockets to store your water bottle and other items. Even sockets are quite useful that let you store the cellphones and devices when charging.

12. Budget:

Not only for a solar backpack, yet we recommend you set a specific price range before buying any product. Thus, it helps to narrow down your search options and thereby ease up your decision process. The general price range of solar backpacks will be $30 – $500, based on their size, power, and charging time. Irrespective of the price, it is quite essential to pick a backpack that perfectly suits your requirement.

13. Warranty:

If you are getting a backpack, then it is highly important to make sure that it is a strong one so that all the items inside it stay safe and secure. One of the simplest ways to ensure this is to check the warranty offered by the solar backpack. Thankfully, most solar backpacks out there come with a 1-year long warranty or longer (2-year, 3-year or 5-year) for your peace of mind. Some models even offer a lifetime warranty, which can easily last for a long time.

What is a Solar Backpack?

A solar backpack has an integrated solar panel on the back, which allow the bag to receive solar energy from the sun, and gets charged as you go outside by wearing it on the back. However, some backpacks have sewn-in solar panels, while others have detachable panels that can be placed anywhere to charge effectively.

One has to use this solar energy to charge their devices like smartphones, laptops, tablets, cameras, etc. A few high-end models have power banks included, which means the solar energy is stored in the power bank and then use whenever you need to charge the devices. Other solar backpack models forcefully let you charge the device immediately with the solar energy, as it cannot be stored for later use.

The solar backpacks are available in various sizes, and you need to choose them based on your requirements. For instance, pick a small 15-liter backpack that is meant for storing tablets, smartphones, and laptops. Or choose a larger 40-liter (or more) bag designed for hiking, camping, and outdoor pursuits.

Some solar-powered backpacks offer power banks to charge up the power bank from both sources – electric AC wall outlet and sunlight. This is a good idea to use a combination of two and thereby prevent you from running out of the power to charge devices.

How does a Solar Backpack Work?

A solar-powered backpack is one of the best modern technology that creates and promotes green energy. So, it becomes a convenient option for hikers and campers to charge and use electronic devices on trips. Usually, a solar charging backpack comes with a monocrystalline solar panel, charge controller, battery, cords, plugs, and light bulbs. With all this setup, they offer a power of 120W per day that is more than enough to charge devices.

The solar panels of the backpack will collect solar energy with its built-in photovoltaic cells and semiconductor. Whenever the sunlight hits the solar panel, then the semiconductor absorbs this power to produce an electric current. Then this produced current is sent to charge either lithium-ion battery or controller for later use (based on how your backpack work).

Usually, a panel with an hour charge of sunlight is sufficient to charge the smartphones for about 1.5 hours. If having a lot of devices, ensure to charge the backpack for about 10 hours. It offers nearly 15 hours of stored energy.

Here, the solar panels are placed at the back of the bag, and this design will allow the backpack to charge comfortably, while walking. Mostly these panels are waterproof and lightweight that can produce 4 watts of power based on the circumstances.

Apart from its charging, solar backpacks offer various free plugs and wires based on the brand/manufacturer. Few bags offer USB plugs and cellphone adapters. All these will make you convenient to use, particularly while having a lot of devices.
