1. ECEEN Solar Backpack

  • High-efficiency photovoltaic cells for improved energy transfer efficiency
  • Removable solar panel for greater backpack versatility
  • Can charge multiple devices
  • Lightweight, weatherproof, and durable backpack design
  • Various pockets and compartments for different items
  • Capacity is not large enough for several days’ worth of clothing

The ECEEN solar panel bag has all the makings of a good-quality bag for people who are always on the go. This solar panel bag comes with advanced technology that harnesses the energy of the sun more efficiently than other similar products.

What we love about the ECEEN are its high-efficiency photovoltaic cells. It has an energy transfer efficiency that can shame larger systems. This can translate to better solar energy gathering and its eventual conversion into usable DC power. The surface of the solar panels also comes with adequate protection against the elements, scratches, and bumps.

Because of the small size of the solar panels, it will never detract from both the aesthetics and functionality of the backpack. There are pockets galore for every item and gadget in your arsenal. The main compartment features enough padding to accommodate sensitive equipment. You can stow your tablet or laptop without risking its integrity. There are hidden, zippered pockets, too, for securing more valuable belongings.

The Eceen solar backpack comes with a ripstop fabric material. No brush or twig will ever be sharp enough to cut through the material. And when it comes to a downpour, the ECEEN backpack will protect the things you put inside. The stress points come with bartack reinforcements. Regardless of the kind of outdoor adventure you have in mind, the ECEEN will get you there.

The most useful part of it is that you can charge all of your modern devices wherever you are. You no longer have to fuss about the unavailability of an outlet for charging your gadgets. You’ve got one right on your back.

The only downside of the ECEEN is its capacity. It is, nevertheless, great for light traveling or a day-long trek on the trails. It is also a trustworthy carriage system for a daily commuter.

2. FESTI 13L Solar Hydration Backpack

  • Slow to charge the devices

FESTI might look like an ordinary bag with solar panel, but its design is as thoughtful as a military-grade outfit. There are many things to love about this bag, and I will start with its photovoltaic cell technology.

Most solar bags feature polycrystalline solar panels to make them affordable without undermining solar efficiency. However, why should I be content with a 15% efficient PV panel when I could harness 22% of the sun’s energy and turn it into DC electricity? That is what this solar bag offers – a highly efficient monocrystalline solar panel.

Its high-efficiency PV cells translate to faster solar charging. While most solar bags need at least 6 hours under the sun to charge built-in batteries, this solar backpack only requires 4 hours of sunlight to fill its 10Ah power bank. That is enough to recharge two USB-ported mobile devices simultaneously, making this backpack a favorite of digital nomads.

Now, this solar backpack does not only provide power anywhere. It also keeps the body well-hydrated, thanks to its built-in two-liter water reservoir with an integrated drinking hose. The bladder has a protective layer to insulate the 13-liter main backpack compartment against accidental spills.

Such a capacity is sufficient for everyday items. A netbook, tablet, personal effects, and other stuff can fit right in. I like the dedicated electronic pocket to secure objects with sensitive parts.

Wearing this bag on the back is surprisingly comfortable. It has adequate back padding, a dual-channel airflow system, and fully adjustable shoulder straps. The lumbar and sternal straps are also noteworthy, perfect for effortless and safe de-loading.

Although I appreciate this solar system backpack, I wish its charging cables could deliver more power to mobile devices to speed up recharging.

Electric Source

Solar backpacks provide an alternative electric source. Aside from outdoor activities, these backpacks are useful in out-of-the-grid locations and sometimes for humanitarian aid and relief. In these situations, people usually struggle due to a lack of electricity. However, with a solar backpack, people can still access and use power.

Moreover, they are easy to charge since they rely on an unlimited and constant energy source, the sun.


Solar backpacks are also quite durable. They are made out of rugged and heavy-duty materials and feature a design that can withstand most weather conditions.

Aside from that, the electronic components are also durable. The solar panels are lightweight and waterproof, protecting it from harsh weather. The cords and wires can also be stored inside the backpack when it rains and the like.


Limited Electric Capacity

Solar backpacks, while convenient, provide only a limited supply of energy. Most solar backpacks can only produce about 55 watts of power per day. Compared to a generator or a stable electric source, this charge is certainly not enough if you plan on sharing the backpack among several people.

Long Charging Hours

Like all solar-energy devices, solar backpacks take some time to charge. On a one-hour charge, the backpack will generate about 120 watts, which is enough to charge a cellphone for 1.5 hours.

However, if you bring along multiple devices, you’ll need more than 120 watts. To get the full charge of your solar backpack, you might need to charge it for 10 hours or more, depending on the weather condition. Perhaps, it is one of the weaknesses of a solar panel backpack that might turn you off from buying it.

How We Picked And Testedbest-solar-powered-backpack

Solar backpacks provide the most suitable of both worlds. They act as a regular backpack, offering you a space for your clothes and other essentials. At the same time, they also act as an electric source, allowing you to charge your devices while outdoors.

With this, they are quite popular among hiking and camping activities. Such a bag is also useful among those who live off-grid and during humanitarian relief operations.

Due to this popularity, solar backpacks come in different styles, designs, and features. It might make things difficult, especially for a beginner.

However, you don’t have to worry. Here are some tips and factors you can keep in mind while out shopping.

Weight, volume, durability

As in their name, backpacks are worn on your back. As such, you would want one that is a reasonable weight to carry. It is especially important if you plan to use the backpack for outdoor use.

Go for a lightweight solar backpack that you’ll feel comfortable walking/hiking with each time. If you can, avoid a bulky design as this can be distracting and add unnecessary weight on your back.

As for durability, choose a solar backpack that is made out of top-notch materials. Regardless of its application, choose one that can withstand harsh weather conditions. At the very least, it should be waterproof and dust- and shock-resistant.

Solar and battery power

Your solar backpack should be able to accommodate several devices- at least the number of tools and gadgets you are aiming to bring along with you on your trip.

If you want, choose one with a high-capacity solar panel that can charge and generate a decent amount of electricity in the shortest amount of time.

Lithium-ion batteries are also the preferred ones since they have proved to be quite durable and long-lasting.

Aside from that, you must also find a solar backpack that can store the remaining charge in the battery.

Charging Time

Related to the second requirement is the charging time required for your solar backpack. It’s essential to consider the charging time your bag needs.

Higher-capacity solar panels require more charging time and, thus, more patience. However, they tend to give the most significant and extended charge. On the other hand, lower-capacity panels are faster to charge, but they can also run out of power faster.

Pockets, sockets, wires, plugs

It’s essential to choose a solar backpack that provides several cables and plugs. This way, you can charge and accommodate your electronic devices with you.

It is also ideal to look for a backpack that comes with several pockets for your water and other items. Sockets are also useful since they can store your cell phones and devices while charging.


Before purchasing a solar backpack, it’s recommended that you set out a price range first. This way, you can effectively narrow down your list of options and make the process easier.

However, regardless of the price, it is essential to look for a backpack that can suit and meet all your needs.
