We appreciated the robust construction, which stood up well to the rigors of travel. The materials used also speak volumes about the brand’s commitment to sustainability, by incorporating recycled PET fabrics, they’re not just offering a solution to keep our gadgets powered, but are also doing so in an eco-conscious way.

While the added functionality of the solar panels does increase the bag’s weight, we found the trade-off worth it for the utility it provides. However, we did notice that the charging capability is significantly impacted by weather conditions, which is an important consideration for those who frequent overcast environments.

In summary, the Voltaic Array Rapid Charger is a solid choice for individuals in need of a reliable solar charging solution while on the move. It’s designed to cater to the needs of modern-day adventurers who value both function and sustainability.

Festi Solar Pack

Charging devices with a solar backpack is awesome way to travel

We found this pack to be a game-changer for our outdoor jaunts, offering hydration and power on the go.


  • Eco-friendly charging source with quick charge capability
  • Comfortable design and light weight make for an easy carry
  • Water-resistant construction protects gear and electronics


  • Limited storage capacity may not suffice for longer trips
  • Narrow side pockets restrict the size of additional water bottles
  • Charging performance may drop in less-than-ideal sunlight conditions

Toting the Festi Solar Pack through the wilderness, we admired the way it bridged modern conveniences with outdoor adventures. The integrated solar panel impressed us, not only because it’s environmentally friendly, but it kept our devices charged even during prolonged treks. Especially useful was the quick charge feature, giving our smartphones a boost from 0 to 100% in mere hours under direct sunlight—a lifesaver when we needed to stay connected or use GPS apps.

Comfort was another highlight. The raised foam back design allowed for continuous airflow, minimizing sweat during hikes or bike rides. The bag’s straps were a breeze to adjust, and no matter the terrain, the lightweight build meant we barely felt it on our backs. From summit climbs to leisurely forest walks, it stayed snug and secure without any digging into shoulders.

However, it’s not without its limitations. The 13L capacity seemed a tad restrictive, making it necessary for us to pack wisely. Larger items and additional gear that we might carry on longer treks would have to be left behind. And while the side pockets held the provided hydration bladder fine, they weren’t the best fit for some of the wider bottles we usually carry.

Despite these minor grips, our tech stayed dry thanks to the water-resistant nylon material—even when we got caught in a light drizzle. Plus, the durability of the design means we’re confident it will accompany us on many more excursions. The Festi Solar Pack has become a staple for our outdoor festivals and day hikes, and we’d recommend it for anyone in need of a reliable, eco-friendly charge, and hydration while exploring the great outdoors.

On my recent weekend hike, our ECEEN Solar Backpack proved to be a handy companion. Its compact foldable design let us stash it in our larger camping gear effortlessly. Pulling it out when needed, we appreciated how it unfolded into a full-size backpack without a hitch.

The solar charger impressed us with its detachability, allowing us to power up devices even when the backpack was not on our shoulders. As we walked under the sun, our phones remained charged, granting us peace of mind and connectivity throughout the journey.

We noticed, however, the material felt a tad too thin, casting some doubts on the backpack’s long-term resilience. This was felt especially in rougher terrains where ruggedness is a virtue. In addition, the straps weren’t the pinnacle of comfort, a bit of a miss on ECEEN’s part, as all-day treks demand better ergonomics.

The charging proficiency varied as well. There were moments, particularly on cloudier days, when the solar panels seemed less effective. Yet, when the sun was generous, our gadgets soaked up the power without fuss.

All told, our experience tells us the ECEEN Solar Backpack is suitable for occasional hikers and outdoor enthusiasts who value lightness and solar power convenience over heavy-duty wear and tear.

Storage was another of this pack’s strengths. With its spacious main compartment and dedicated pouches for various gear, including a separate shoe compartment, we found a spot for everything. This compartmentalization was a boon for efficiency and convenience, especially when our journey involved frequent stops and starts. Plus, the numerous external hooks and straps made lugging along extra equipment like sleeping bags a cinch.

Despite its sterling qualities, it’s worth mentioning that the backpack might not be as robust as some might need for extreme or prolonged adventures. However, for most hikers and casual explorers, the ECEEN backpack is a stout-hearted ally under the sun.

Buying Guide

Importance of Solar Panel Efficiency

When we select a solar-powered backpack, the efficiency of the solar panels is crucial. High-efficiency panels convert more sunlight into electrical energy, providing more power to charge our devices.

Battery Capacity

We must consider the battery capacity, which is measured in milliampere-hours (mAh). A larger capacity means the backpack can store more energy, allowing us to charge our devices multiple times.


The material of the backpack should be durable and weather-resistant to protect our electronics and solar panels from damage. We look for backpacks made from high-quality, sturdy materials such as nylon or polyester.

Portability and Comfort

The backpack should be lightweight and have comfortable straps, as we will be carrying it for extended periods. We check for padding on the straps and back panel, as well as the overall weight of the backpack.

Panel EfficiencyHigher efficiency for better sunlight conversion
Battery CapacityMeasured in mAh; higher for longer use
MaterialDurable, weather-resistant materials like nylon
ComfortLightweight, padded straps and back panel

Extra Features

We also take note of any additional features such as USB ports, LED indicators, integrated locks, and multiple compartments. These can enhance the backpack’s functionality and convenience.

Price vs. Performance

Finally, we balance the cost against the backpack’s features and efficiency. We aim for the best value, where the price aligns with the backpack’s performance and build quality, without paying for unnecessary extras.
