    What is a Solar Powered Backpack?

    A solar powered backpack is a backpack with at least one solar panel (made from monocrystalline) that converts sun energy to charge your phone, camera, or other electronic devices in a safe, eco-friendly manner. It can be used as a regular laptop backpack for travel even if you don’t use the solar charger.

    The solar panel can be built or sewn in, or it can be attached and detached from the backpack. The backpack can also have a power bank or lithium-ion battery system, which is where the sun energy is stored so you can charge your devices. In order to charge your devices on the go, it’s useful if the backpack includes a USB external port or at least a cable passthrough so that the power bank or travel charging organizer can stay inside the backpack while connected to your device on the outside.

    If the backpack doesn’t have a battery or doesn’t give you the option to add your own, then you can only charge your devices as long as there is sun for the solar panels to “soak up” the sun’s energy. No sun equals no charge. 

    But if the backpack comes with a power bank, then the sun’s energy is stored in the battery system, meaning you can charge your device as long as the batteries have stored energy. It doesn’t matter if it’s dark or you’re indoors.

    Solgaard LifepackThe SOLGAARD Lifepack Solar Powered Backpack is ideal for traveling, as it features anti-theft technology while the 10,000 mAh battery solar bank can charge your devices on-the-go. You can also buy just the backpack if you already have a compatible solar or power bank.

Plus, a fully charged Solarbank means you can charge your phone 5 times.

    The backpack also has an integrated USB port, so you can plug in your phone and still use it while on the go. However, you can also safely charge your devices in your backpack. There are 4 secret passport or card pockets. With the patented anti-theft lock, your valuables are kept safe.

    The bag stands upright on its water-resistant bottom when you aren’t carrying it around, so you don’t need to worry about it falling over. There is also drop-proof laptop storage, so your laptop is safe. 

    The backpack is made from Shore-Tex, a green fabric made from upcycled ocean plastic. It is divided into two compartments: a lifezone where you can keep your sunglasses, keys, and clothes, and a workzone for your laptop, notebook, etc. There’s a water bottle pocket on the side of the bag as well as a mounting point to hang an accessory off of.

    The dimensions of the backpack are 11.6” x 18.5” x 7” and the Solarbank measures 6.2” x 3.5” x 0.5”. The bag with the Solarbank weighs 1.75 pounds, so it’s lightweight, making it ideal for travel or hiking.

    Things to Consider When Buying a Solar Travel Backpack

    So what’s the best solar powered backpack? It’s essential to keep these aspects in mind: 

    Capacity

    The capacity of the backpack means two things. The first is how much volume the backpack can hold. The size of a backpack is usually measured in liters. For example, a 15-liter backpack is great for a laptop and smartphone while a 45-liter backpack is better suited for hikers, campers, and photographers. 

    How big the backpack should be also depends on how many days you’ll be traveling or hiking away from places you can do your laundry and replenish food and drink stocks. 

    The second capacity aspect is how many solar panels you’d need on the backpack. The more things you want to charge, the bigger the solar panels or battery system. The same goes for how often you need to charge your devices. 

    How Will You Use the Bag?

    How you’ll use the backpack also influences what kind of solar-powered backpack you need. If you need a backpack for travel photography, you need to ensure you can safely store your camera, lenses, cables, clothes, and whatever else you need in the bag. 

    However, if you go hiking, you have different gear and may need to carry your own water and food. 

    If you are traveling in the rain, then a waterproof backpack is a must. 

    What Do You Want to Charge?

    What you want to charge and how will often give you an indication of the solar power capacity and battery power you need. Another aspect here is how quickly you want your device to charge. 

    For example, if you want to charge your smartphone, the solar panels need to be at least 5 watt. A 5-watt solar panel generates 5 volts of power, which is enough to charge your phone. 

    A high-capacity solar panel will charge your phone in 2-3 hours, while a low-capacity, cheaper model will take 5+ hours to charge your phone. However, how much sun the panel gets also affects the speed of charging your devices. 

    You’d also want to consider the power usage, which is measured in milliampere-hours (mAh). If you choose a 2,500 mAh solar backpack, then it’ll take 2.5 hours to charge a 1,000 mAh device. So check the mAh of the devices you want to charge and what the solar backpack offers. 

    Check the energy efficiency transfer rating of the solar panel too. A rating of 15-18% is the average efficiency rating; the higher the rating, the more energy output. A rating of 20% or more means the solar panel is very efficient. If the rating is 22%, for example, it means the solar panel converts 22% of the sun’s irradiance into usable electricity.   

    Ease of Carry

    No one wants to lug a backpack around that puts strain on their shoulders within the first 30 minutes to an hour of their trip. So how easy the backpack is to carry is a key consideration. 

    Look at the shoulder padding and the ergonomics of the backpack. Consider how lightweight the backpack is when empty because you don’t want extra weight that doesn’t have value. 

    Durability

    If you spend a lot of time outdoors, then you need a backpack that is durable. Plus, the best solar panel backpacks aren’t cheap, so you want a return on your investment. 

    Ensure the backpack is made from high-quality materials and is weatherproof to protect the battery pack (either included or your own). Plus, the solar panel should be durable too. 

     

    FAQs

    How long do solar backpacks last?

    On average, high-quality solar panels can last 25-30 years; however, the company’s warranty most likely won’t back the solar panels or backpack for that period. Most backpacks have a 1-2 year warranty, but check the fine print to ensure you are fully covered.

    Are solar battery packs worth it?

    Solar battery packs are worth every penny if you need to charge your electronic devices and aren’t near an electrical power outlet while traveling, hiking, or engaging in other outdoor activities. Depending on the power capacity of the solar battery pack and your device, you can recharge your smartphone up to 5 times on a fully charged solar power bank before the power bank itself needs to be charged by the sun.
