Solar Backpacks – Should You Buy One ?



We simply cannot live without our phones and tablets. Keeping them charged and working for the entire day can be quite a challenge. As phones get smarter, they consume more and more battery life. With the use of mobile internet, it can get even worse. For people who are constantly on the move, this can cause some major anxiety. Good thing solar backpacks were invented! They offer one of the best solutions to charging gadgets when you simply do not have access to an outlet or power stick.

How It Works

Each solar backpack has a built-in solar panel that converts solar energy into regulated power, which can be used to charge almost any mobile device. There are two ways to charge a device: it can be plugged directly to the cable connected to the solar panel or you may use an optional rechargeable powerstick to charge it later.

Types of Devices

Solar backpacks can charge most types of mobile devices such as smartphones, tablets, digital cameras, video cameras, game consoles and even laptops. For campers or those who live in remote areas, they are useful in giving necessary extended power to FM radios and portable lamps.

The usual charging time for a solar backpack ranges between two and four hours on a bright and sunny day. It can give you one full charge on a smartphone. Charging times will increase accordingly in cloudy or low light conditions. It may also depend on how large your gadget’s battery is. For those who own smartphones with larger batteries (e.g. 3,000 mah), charging will definitely take much longer. The good news is that it should get you through the day or at least until you find an outlet where you can plug your device.

Options available

When buying a solar backpack, it is important to make sure the thin-film photoelectric solar panel is built well and does not look flimsy. It should not add weight to the bag so it can be used as normal.

Since most of us own more than one gadget these days, it is best to look for ones with several cable options. Standard ones include 2-3 adapters but pricier solar backpacks can include up to 8 adapters for iPad, iPhone, USB-devices, and more.

Perhaps the most important thing to take note is that it is still a backpack! Utility is as important as its charging power. Standard ones have a multiple sections for laptops and other stuff such as your books. Smaller pockets can accommodate other smaller gadgets like phones and MP3 players.

Design choices may vary. Most people would probably prefer backpacks where the solar panels are incorporated into the design. Others turn from backpacks into messenger bags with just a quick change of a strap. While messenger bags and tote bags are also available and increasingly popular, you will get more charging time with a backpack due to the position of the panel on your back.

Should you buy one?

Unless you are an outdoors-type of person, waiting for your phone to charge under the heat of the sun may not sound like a great idea. It should be great for campers, hikers or people who like attending festivals and outdoor concerts. Students can definitely take advantage of getting some extra juice for their tablets or laptops during their breaks.

The size of these backpacks may appear clunky to some people. However, the benefits help anyone look beyond that. Anyone who wants to any available option to charge their phones on the go must consider having one.
