Buyer’s Guide – How to Choose a Solar Backpacks
This backpack charges gadgets thanks to the energy received from the sun by its monocrystalline panel, which receives it and accumulates it in the battery. This device is equipped with adapters for almost all popular brands of devices, and also equipped with a mini USB adapter.
To make the right choice, you need to determine what this backpack with built-in solar panels is for. Going on the road, the traveler will certainly take care of fully charging before the exit all his gadgets – phone, photo and video camera, laptop, navigator, player. If it is a short (one or two-day) trip out of town, it is unlikely that someone will take a laptop to work on it without interruption until the battery is completely discharged. And for recharging the batteries of any other portable device, a relatively small solar battery is sufficient.
It is difficult to imagine that during the journey the sun will always shine only in the back, allowing the batteries to produce the maximum possible electric current. That is why, the panel should be removable, but with the ability to mount on the backpack in such a way that during the movement it is possible to provide the maximum charge current. The system of fastenings of such a panel should be that it can easily be fixed, for example, on a tent.
How to Choose
Weight
The weight of the solar backpack matters if you’re going on a long trip. It’s obvious that the backpack will weight a lot as you take all the necessary stuff so the lighter backpack itself is the better. However, heavy solar backpack points at higher volume and power.
Size and Volume
The volume of the solar backpack depends on its use. Compact backpack can be used in town or for 1-2 days trips. The big backpack is great for longer trips, so you can put plenty of things. Again, this feature depends on what you’re going to use this backpack for.
Power Capacity and Battery Power
The solar capacity and battery power depend on how often you use your electronic devices. There are solar backpacks that provide enough energy to keep cell phone charged. It’s great when you use the phone only when there’s a strong necessity. Other solar backpacks can charge smartphone, GPS unit, DSLR camera and laptop. This is a great choice, who travels far and for a long distances.
Price
The cost is always a major factor in choosing items. The price for the cheapest and expensive solar backpacks should be defined by their features. High price solar backpacks usually have better quality, increased durability and weight less. The really good one backpack that is able to charge any type of electronic device cannot be cheap.
Using Devices While Charging
You simply can’t charge electronic devices while the solar battery is charging. You only can charge the device when the panel is full enough of solar energy. If you charge devices during the day then the solar panel is not able to refill its energy.
Ports
It’s better the backpack have as many USB ports as possible. Most solar backpacks come with only 1 port so it’s possible to charge one device. Expensive backpacks come with 2 ports and more. If you’re going to use it charging more than just a phone then you shouldn’t save money for a cheap one model.
Durability
Taking this backpack outdoors means it should be tough and it’s better the pack is made of nylon. This fabric can resist the water, it’s tough and rather durable. The seams of the backpack and stress points should be reinforced and triple stitching also should be included. Consider that the pack has to be flexible and able to take the elements.
Conclusion
As a rule, solar panels are located on the most sun-exposed part of the backpack. The backpack design provides for them a special pocket-compartment, fixing the batteries and protecting them from mechanical damage. The battery itself is a thin flexible sheet with thousands of photoelectric converters needed to transform the energy of the sun into electric current. The resulting energy is stored in a battery with a USB port, for which there is also a special place in the backpack. The most powerful models of solar panels and batteries can be used not only for charging all kinds of gadgets, but also for lighting tents, the work of small household appliances up to 150W. The capacity of built-in backpacks batteries in some models reaches 24 000 mAh. Choosing the solar backpack depends on your needs and the devices you tend to use.
