A solar backpack is a special type of the conventional backpack which has a tinny film of solar cells and batteries. Whereby, the thin film solar panels convert sunlight energy into electric power. The solar backpack also has suspended traps that let you carry it steadily on your back.
In this post, I share with you the unique features of the best solar backpacks and a few models you’d consider when buying a solar backpack. The solar backpacks are the latest type of backpacks, thanks to consistent advancement of technology.
Before these bags came you’d not charge your important gadgets when hiking but nature really doesn’t dictate that you have to stop operating your gadgets when having fun hiking. An ideal solar backpack has an added advantage as compared to the usual backpacks in that, it enables you to charge your devices .
Since hiking is most exciting on sunny days, having a solar panel at your back while hiking in the presence of sunlight would be a great way to recharge the batteries while doing what you love. So whenever you want to leave for a hike, you don’t have to waste a lot of time charging your phone ahead of the trip when you can charge it while enjoying the trip.
Instead, you can use your last minutes before the trip to make proper preparations rather than waste it on charging gadgets. Moreover, you won’t have to cut your trip short just because there is low charge in your laptop, cell phone or tablet.
5 Things to Consider While Buying Solar Backpacks
Every time you go out buying anything it’s always prudent to carry a checklist. A checklist is a very vital tool that will help you know if whatever you settle on will satisfy your needs. So consider this a checklist for solar backpacks. Here are some features that a basic solar backpack should have:
Lightweight, Portable and Durable
A good solar backpack should be made of lightweight materials. If they are made of heavy weight materials you will have to carry a lot of dead weight on your shoulders. The only weight you have to carry should be the weight of your items and not the weight of the back.
So when you are out choosing a solar backpack, be sure to go for something light. However light, the material should be strong enough to withstand the heavy duty it’s subjected to during the hike. Additionally, it should be waterproof to keep your items safe from unexpected downpour.
Integrated Power Bank
Solar backpacks have solar panels which are transducers. They convert sun rays into electric power. A good backpack should have a sufficient power storage system to conserve the power so that you can use it whenever you need to. An integrated power bank is an awesome solution to power preservation. The more power it can save the better.
Sockets and Pockets
Pockets and sleeves are good for planning purposes. If your backpack has pockets you will know exactly where to put what item. However, the pockets should be big enough to store all your ideal hiking items.
A good backpack should also have a large compartment for your clothes. Considering that the bag is part of an electric system, it should have accessible sockets that let your charge your gadgets conveniently while on the go.
Padded Laptop Sleeve
If you’re going on a long trip then I assume you might want to carry your laptop. A good design should have a laptop compartment or a laptop sleeve that tightly holds onto the laptop so that it doesn’t move inside the bag as you move. The backpack should be well padded so that the pads absorb all the shock waves from knocks that would damage the laptop.
Detachable Solar Socket
Since the solar panel is attached to the backside of the solar backpack, the backpack will automatically generate electric power and instantly store it in the power bank. However, there are occasions when the backside of the backpack will be facing away from the sunlight and this could be the moment when you need the power most.
On such occasions you’d consider detaching the solar panel and attaching it somewhere else where the sun rays hit the solar cells, so a detachable solar socket would be handy. I would recommend the detachable solar cells any day.
Which features you should look for?
Well, the solar backpack just unlike any other backpacks have some unique features which set them apart from other bags out there in the market. Here are some of those features:
The material of a backpack determines its quality and also its weight, whether it will be heavy or light. Therefore, the type of material really matters especially to those who are keen about what the backpack is made of. Most solar backpacks are made of durable, high quality waterproof materials.
The Solar Power
This solely depends with the type of gadget you will be charging. Some gadgets such as laptops that require relatively higher power input as compared to phones and flashlight so they might require solar backpacks with batteries of higher voltage to ensure less charging time.
The Number of Panels
The number of solar panels have a direct bearing on the charging capabilities of the backpack charging system. If the system has many solar panels it will store more charge, faster in the batteries. More solar panels translates to more power to sustain you longer when hiking.
However, the decision to add more panels to it will squarely depend on your needs and you may have to pay more for it.
