Solar Backpacks System – Developed by The U.S. Army
Thanks to the solar backpack system developed by the United States Army Communications-Electronics Research, Development and Engineering Center, its Rucksack Enhanced Portable Power System (REPPS) paved the way to the development of the latest life-saving and environment-friendly innovation called the solar powered-backpacks.
Aside from keeping your phone and other wearable electronic devices fully charged, solar backpacks are also of great importance in helping students and individuals in rural areas where access to electricity are unavailable.
What Is A Solar Backpack?
A solar backpack is a cloth sack carried on one’s back that is equipped with thin film solar cells and batteries. With the right technology, the solar panels can convert sunlight into energy and store it in the batteries. Hence, these devices can be a great source of electricity to power portable electronic gadgets and handheld devices such as mobile phones, digital cameras, mp3 players, laptops and tablets in a safe and secure manner.
The solar backpack’s original design is known as the REPPS (Rucksack Enhanced Portable Power System). It was initially intended for the use of the United States Army Communications-Electronics Research, Development, and Engineering Center.
Solar Backpack Features
Generally, solar backpacks has a flexible monocrystalline solar panel, charge controller, light bulbs, cords, plugs and batteries. It usually offers power up to 120 watt-hours/day, making it capable of charging electronic equipment rated up to 300 watts.

Considering its potential uses, people can be very excited in purchasing one. But take note, there are factors to consider since buying them are not that easy. In fact, there is a wide-range of solar backpacks available in the market. But to sum it up, here are some important things to consider:
1. Weight, Size, Volume and Durability
Whether you’re going to use it on your next outdoor adventure or perhaps on relief operations, you should always choose a solar backpack that is lightweight and durable. The reason? A backpack’s weight is an important factor as the distance of the hikes increases.
Size and volume, on the other hand, can be directly related to its use. For example, a heavier bag would mean you will carry less gear, food and water, as well as other important necessities. So, if you are planning to hike longer, then a light-weight one is more preferable.
As for durability, you should choose a solar backpack that is made of high-quality materials that can withstand rugged terrain and extreme weather conditions. It should also be waterproof, as well as dust and shock resistant.
2. Solar Power Capacity and Battery Power
Solar power capacity and battery power should be among the factors you should consider before purchasing a solar backpack. The ideal capacity, however, depends on your attachment to your electronic gadgets. But it is highly recommended to choose the ones that allow you to charge your mobile phones, cameras or laptops.
Moreover, you must also consider the ability of these devices to store excess power, which can be used in cases of emergency.
3. Sockets, Pockets and Detachable Solar Sockets
Since you’ll be carrying a lot of things in your backpack, it is ideal to use those that have several pockets for drinking water bottle and first aid kits. Sockets, on the other hand, can be utilized when storing smartphones and cameras while they are being charged.
As for a detachable solar socket, it’s highly recommended to find a solar backpack with detachable solar sockets and expandable cables. The reason? It gives you an opportunity to place the solar socket outside your tent or vehicle while ensuring the safety of the stuffs in your bag.
4. Charging Time Requirements
Before buying a solar backpack, you should consider the length of charging of the product, which refers to the length of exposure to the sun to achieve a full charge state. Remember, longer charging times mean more patience and waiting time are needed before the product becomes fully functional.
The last but equally important factor to consider in buying these devices is the budget. It is best to weigh the advantages and disadvantages when buying cheap solar phone chargers than an expensive one and vice-versa. But remember, an expensive product usually correlates with better quality and durability. So, it’s better to choose the best solar backpack that can be considered an investment and suits your needs. After all, money well spent in a product that will last for years is worth it.

Other Suggested Solar Backpack Brands
Meanwhile, we wanted this article to be helpful and comprehensive as much as possible. So aside from the aforementioned brands, we will also include a brief overview of other suggested and popular solar backpack brands available in the market.
1. HiTech Ninja Solar Power Backpack – This product is one of the top 10 gadgets presented at the CES (Consumer Technology Association) 2017 held in Las Vegas, Nevada this month. It boasts its SunPower American Made Crystal Silicon in High Efficiency 6V/6.5W Solar Panel with USB output.

Solar Backpack to Avoid
If there are highly recommendable products, there is also a solar backpack to avoid. This is the Ivation 3W with 2 Built-in Speakers. The product is reportedly similar to the backpack version of the calculator watches, which were popular with the kids in the 90s.
Although it has a lot of functionality, the concept of the product was not properly executed. For less than $100, you can get a much better backpack with more powerful panels and a higher capacity battery.
If you are so inclined with the speakers, which seems to be the only thing this backpack has caught the attention of some consumers, you could probably get better speakers for just $5 compared to the ones that are included on this bag. Its 3W solar panel is also not a powerful solar charging as it would take you a full day of sun exposure to give your phone a noticeable charge.
Moreover, its 2,200 mAh power bank is also not enough to even give your phone a full charge. Most reviews also show that this backpack is of low-quality, making it fall apart almost immediately. So, better save your money and look for something better. Always remember, solar backpacks can be a good investment too.
