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.

5. Budget

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.
