Why Do You Need a Solar Backpack For Your Next Outdoor Adventure?
If you are planning to go hiking in a national park or camping in the woods, you need to have your electronic devices to help you navigate your location. Not only that, you need your smartphone to keep in touch with your friends and family in case of an emergency.
Furthermore, you might want to take pictures of the scenic environment while you’re out there. You need to charge your camera but you may not get a charging port inside a forest or any other rustic environment.
Therefore, it is crucial to keep your electronic items fully charged while you’re enjoying your outdoor adventure. A solar backpack provides you with a charging port anytime you need wherever you are.
In general, solar panels do not weigh much. They let you charge all kinds of electronic devices such as smartphones, cameras, MP3, GPS devices, speakers, etc. You won’t face trouble carrying it around while hiking and also get numerous benefits out of it. Thus you should consider purchasing a solar backpack before going on such ventures.
Buyers’ Guide - How to Select The Best Solar Backpack?
Solar backpacks can make your outdoor ventures exciting with its several benefits. But if you do not purchase the right backpack that satisfies your needs, you will have to face several issues instead of enjoying your time.
We have mentioned some of the important things to consider while purchasing a perfect solar backpack based on your requirements.
Solar Power Capacity
The solar panels attached to such backpacks generate a certain amount of power. Solar panels are compact and do not produce as much power as a normal panel used for the household purpose can generate. Generally, they generate about 3 to 5 watts per hour based on the device size and specifications. Some backpacks, however, include panels with higher power capacity.
Charging Time
You need to make sure your devices do not take much time to charge when connected to the solar panel. The power generated from solar panels, combined with the battery capacity, determines the charging time. A large solar panel generates more power and thus can charge your equipment faster. But they are difficult to carry, due to its heavyweight.
Voltage
Various electrical equipment requires different voltage settings while charging. Most of the smartphones and tablets require 5 Volts to charge its battery while other heavy equipment, such as laptops, require much more. Thus you need to select your backpack based on the specific voltage setting that your device requires.
Battery Power and Usage
Some of the solar backpacks include a battery to store the energy generated. Most of the backpacks equip a smaller battery that can charge only smaller USB devices such as mobile phones. If you want to charge large equipment, such as a camera, you need to select a product with higher battery power.
However, some backpacks do not include batteries at all. In such cases, you need to charge your devices directly from the USB port situated on the solar panel.
Weight and Size
The dimensions and materials used for the production of the backpack determine its weight. Apart from that, the solar panel’s dimension also determines its weight. If you want a powerful solar panel that can charge heavy equipment such as laptops and cameras then your backpack might get heavy.
A heavy backpack might be difficult to carry around while hiking. Since you are also going to add personal items inside the bag, you should take its weight as an important factor to consider.
Pockets and Compartments
Your solar backpack must include several pockets and compartments for you to store your electrical appliances while traveling. You will use this backpack to store your personal items as well, so it should include different compartments and pockets to hold different items.
Most of the solar backpacks let you remove the solar panel when not in use. Thus, you need a special compartment inside the backpack to store it.
Frequently Asked Questions (FAQ)
Most of the solar backpacks do include a battery pack that lets you store additional charge accumulated from the solar panel. Some of them do not provide this feature and thus you can either purchase an external battery pack or charge your appliances only when the sun is out.
The solar panels equipped for your household purposes are strong enough to handle multiple electrical appliances simultaneously. They are huge and are not meant to be carried on your backpack.
Therefore the solar panels that are attached to your backpack are not going to be as powerful as the household ones. So yes, your device will charge slower when connected to this solar panel.
The backpack is constructed to withstand light rainfall, and will not cause any damage to the solar panel and your electronic devices. However, when you carry it during heavy rainfall, it may cause damage to both the items.
Some of the backpacks are waterproof though. But you may consider not taking any risk during extremely heavy rainfall.
