10 Best Solar Backpacks Reviews in 2020 (Buyers Guide)

Are you looking for the best solar backpack to keep all your mobile devices charged while camping or hiking in the great outdoors? Read on to learn more about solar panel backpacks on the market today and probably find one that suits your style, charging needs, and budget.

The smartphone and other mobile devices have revolutionized the way we communicate and stay in touch with family, colleagues today. You can hardly venture out of the house without your smartphone within reach.

The tragedy is that smartphone batteries hardly last a day without charging. The device is not of much use without a power outlet close by. This is a major problem if you are traveling, biking, or hiking in remote locations.

You’ll need a reliable way to keep your smartphone and other devices such as your tablet and laptop charged at all times. This is exactly what a solar backpack does.

The solar backpack is a portable charging station conveniently located on your backpack. It converts solar power into direct current (DC) energy that charges your mobile devices. It is a great tool to have around when your device is running out of juice and the nearest power outlet is miles away.

Advantages of a Solar Power backpacks

If you are walking under the sun why not let Mother Nature save you from a dead phone battery situation?

In this age of information and wireless connectivity, almost everyone uses a cell phone, tablet, iPod, laptop, portable speakers, and other electronic devices.

All these devices need to be charged constantly to keep on working as expected. Unfortunately, we are not always near a power outlet every time. The solar backpack solves this problem by providing you with a portable charging station that you can use wherever and whenever there is sunshine, which is most of the time unless you live in the polar regions.

Best Solar backpacks

The solar pack is basically your normal backpack but with a solar panel attached. The panel provides a convenient way to charge your devices using energy from the sun. You can even charge a battery pack during the day and use it to power your devices at night.

You may ask, why not carry a power bank and charge your devices wherever you are? Well, in my experience, power banks do provide additional and easily portable sources of power but they too have a limit.

You need to be extremely careful about how you use your devices if you are solely relying on a power bank. This is not the case with solar packs. It eliminates all worries and concerns about your device running out of juice.

The best solar power backpack also comes with a hydration pack included. A hydration pack is something you should never leave the house without when going for a hiking, biking, or any other backpacking trip.

When You Need a Solar Backpack

There are many instances when you really need a solar pack to solve your power problems. Here are a few examples:

  • When you are on a backpacking adventure and need a convenient way to charge your devices.
  • Attending weekend festivals? The last thing you need at a festival is your camera or phone suddenly dying on you. A solar backpack ensures this tragedy doesn’t happen.
  • While you are out camping and need to stay in communication with people back at home. The solar pack keeps your devices fully charged whether you are in or away from the campsite.
  • When you go out fishing and need to have your cell phone and other devices charged.
  • While adventure hunting in the woods.
  • You can always carry one of these handy solar packs in your car just in case you are stuck in the woods or run into an emergency situation away from home. The car’s charging system may fail to leave you without any other option except your solar panels on your backpack.

Factors to Consider When Looking for The Best Solar Backpack

There are a few important factors you need to look into when shopping for the best solar pack. I personally recommend you give special attention to the following things;

  • The weight of the Solar Backpack

The weight of the pack is an important thing to check especially if you plan to go on a long hike. A heavier solar backpack will do for short day hikes because you’ll not be carrying a lot of heavy gear such as food and sleeping bags. However, the weight of the backpack becomes an issue if you are going for a long hike or an overnight trek. I recommend getting the lightest solar backpack you can get unless the additional weight is used to provide more volume or solar power.

  • Solar Power Capacity

One of the key distinguishing factors of solar packs is their solar power capacity. This is what makes sola packs different from other backpacks. The right solar capacity of a backpack will largely depend on your needs for electric power to charge your devices. There are solar packs that provide enough power to charge your smartphone while others provide more power to charge multiple devices including your DSLR camera, GPS unit, laptop, and tablet.

Remember to check the backpack’s voltage specification and ensure the voltage is either equal or greater than the power needs of your electronic devices. For example, most USB devices require 5V to charge sufficiently so go for a solar backpack with the 5V specification or more.

  • Construction of the Backpack

You obviously want to invest your money in a durable backpack. If you plan to go hiking or camping in the backcountry, get a well-built backpack that can withstand punishment from the elements. Check the materials used in its construction. I personally recommend nylon because it is water-resistant, tough, and lasts long. You can choose any other tough material but make sure the seams where the straps connect with the backpack are triple stitched to prevent tearing. The solar panels used in the backpack should also be tough and flexible to avoid being damaged by elements. Keep in mind the panels will be exposed to the sun and possibly rain or snow.

  • Size of the Hydration Bladder

Most solar packs come with a hydration bladder to help you carry enough water without the hassle of sticking bottles inside the pack or on the sides. A solar pack with a hydration bladder is highly recommended, especially when you plan to stay out in the wild for a whole day or longer. A good solar pack should ideally have a 2-liter bladder. This will be enough water to keep you hydrated for a whole day.

  • Your Specific Budget for the Backpack

The cost of the solar backpack is another important consideration when purchasing outdoor gear. Solar backpacks come in different price points depending on size and other key features. The best solar pack will feature better quality, less weight, and increased durability but may come at a higher price. However, you don’t have to spend way above your budget in a solar pack with features that you’ll hardly use. There are smaller solar backpacks for people who go on short hikes and probably just need to charge a smartphone only.

If you are a serious camper or hiker planning to spend a lot of time outdoors, I recommend going for the best and most durable solar backpack you can lay your hands on. Consider it as an investment or money well spent. Otherwise, stick to your budget and find the best pack you can get within that budget. 

Solar Power Backpacks FAQ’s

Q. How do solar panels in a backpack work?

A. The solar panels on a solar backpack work in the same way domestic solar panels at homework. They simply convert solar energy from sunlight into Direct Current that can be used to charge your mobile devices when you don’t have a regular wall socket power outlet close by.

Q. How much time does a solar panel on your backpack take to fully charge a smartphone?

A. The time it takes to completely charge a smartphone using a solar backpack depends on many factors such as the smartphone model, its battery size, and the capacity of the solar panel. However, for most smartphones, charging using solar backpack panels takes between 6 and 8 hours.

Q. Can you replace the battery pack on a solar backpack with a more powerful one?

A. Most solar backpacks come with built-in battery packs, which make it impossible to replace the battery or power bank. Fortunately, most of the models we have reviewed above come with powerful battery packs, some with as much as 10,000mAh capacities. In most cases, you won’t need to replace the battery pack.

Q. What is the best water hydration bladder size in a solar backpack?

A. You obviously need as much water as you can carry in a solar backpack’s hydration bladder but keep in mind the more water you load into the pack the heavier it becomes. To find a good balance between hydration and weight, it is recommended to go for a backpack with a hydration bladder of 1.8 to 2 liters. That’s enough water to keep you hydrated throughout the day without having to carry too much weight.

Q. What is the best construction material for a solar backpack?

A. Solar backpacks are designed using a combination of many materials including nylon and PVC. I recommend nylon because it is not only waterproof but durable too.

Final Thoughts
