According to the International Journal of Power Electronics and Drive System, solar is an abundant renewable energy source that can generate sufficient power to meet the planet’s demands. One of the products that use solar energy is the solar backpack.

A solar backpack has photovoltaic panels that can supply you with electricity outdoors. The integrated solar panel is strategically positioned on the back. When the panels are exposed to sunlight, they produce electricity which is either stored in a solar battery or power bank.

According to a publication on ResearchGate, solar backpacks are great for camping and hiking since they allow you to charge different devices. Most solar backpacks can offer 120 watts of energy, sufficient to charge small digital devices. Solar backpacks are also beneficial because they are lightweight, easy to use, eco-friendly, durable, and can resist harsh weather conditions.

When buying a solar backpack, it is essential to consider crucial factors such as the bag size, capacity, wattage, charging time, device voltage, removable solar panels, weight, charging compatibility, and durability.

We tested different types of solar backpacks, including outdoor hiking backpacks, casual backpacks, laptop backpacks, and work backpacks. We assessed their comfort level, charging time, weight, quality, and ease of use in each type. Below is what we found out.
