How to Choose the Best Solar Backpack
Tired of having to charge your cell phone over and over again? Or do you have to limit your productivity in public spaces because you can’t find a charger? For people constantly on the go, and even those of us who enjoy a nice afternoon in the park, a solar backpack just might be the best way of keeping all your gadgets fully functional and still enjoy the great outdoors.
These backpacks have an added value to those of us who enjoy camping and hiking. Now parents can take their children out on a camping trip without worrying about losing touch with home, and the kids can keep their PlayStation charged all the time.
There are however, several considerations to take into account before buying a solar backpack. Even though they offer you practically a lifelong source of charging all your gadgets for free once you buy it, the price range and features of these backpacks vary considerably.
Since there are so many different varieties of solar backpack available in the market, it can easily confuse an average Joe, So, check out these following factors if you want to purchase the best solar backpack for your next expedition –
Sun as a source of power can be very unstable at times (most of the time maybe). Sometimes, the sun may start shining very bright and the solar panels may start producing energy at an extremely faster rate. In such scenarios, electrical devices if plugged in the USB port of the solar backpack could get damaged severely. But it does not have to end in that way. By using a voltage stabilizer, you regain some level of control in such situation.
More often than not, USB devices need 5V and that means, you need to find a solar backpack that has a 5V output.
This is an obvious one right? Of course, it is. Like it or not, your solar backpack is going to get battered by the monstrous forces of nature like a strong wind, rain, and dust. And that means, the solar backpack needs to be made from premium quality materials otherwise it will last very long, ideally, the backpack should be made from nylon as this material is known for its great strength and durability. Double-check the stitching. The seams where the straps are stitched with the backpack should be checked thoroughly. If you find any inconsistency, just stay away from it.
The solar panels should be strong and flexible at the same time otherwise they will break off easily.
Remember, solar panels embedded in your backpack are not going to work that efficiently if you are going on a hike on the misty mountains. If these solar panels get direct sunlight, you would not have to worry about powering bigger and fancier gadgets like laptops or their likes. But sadly this is not the case when the sky is overcast with cloud.
4. Number of Ports
All we can say is that the more, the better. Sometimes, you might need to charge two electrical gadgets at the same time and in such a situation, having multiple USB ports can save your day. Most solar backpacks that are available in the market have at least two USB ports available. So, don’t opt for a cheap solar backpack that only has one port to plug things. Spend a few extra bucks and you will get your hands on a standard solar backpack that has at least two ports.
Often ignored, weight is an important factor when it comes to selecting a solar backpack. Batteries are still inefficient and that means, if you wish to charge large and bulky electrical gadgets, the weight of the solar battery will increase proportionately. The weight of the battery will increase depending on the required capacity. Now, it all up to you at the end. If you don’t mind moving around carrying a lot of weight on your shoulders.
6. Power Usage
Most people find the concept of power usage confusing, to say the least. But the idea is not that complex. Allow us to break it down for you in simple terms. Say for example – you have a 500 mAh electrical gadget and a 2000 mAh solar backpack and that means, the solar backpack will allow you to charge that particular device 4 times. It is just simple math. Power Usage is usually measured in milliamp hours.
Solar Backpacks FAQ’s
Q. Can The Battery Pack of A Solar Backpack Be Replaced?
Ans: Technically, it should be possible but to be honest, it is a bad idea. You might end up damaging the structural integrity of the solar backpack in the process.

Q. How Does Solar Powered Backup work?
Ans: Basically, there is no such difference between rooftop solar panels and backpack solar panels as far as their composition and the inner mechanism is concerned.

Q. Which One is Better – Nylon Solar Backpack or PVC Solar Backpacks?
Ans: Solar backpacks are available in different shapes and sizes and they are made from different materials ranging from PVC to nylon. However, nylon backpack seems to be sturdier and more durable.

Ans: A number of factors at play here. The model of the smartphone, its battery capacity and the capacity of the solar panels determine the time it might need to fully charge a smartphone.
