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 Gameboys 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.
Voltaic solar packs are some of the most practical ones on the market today. They aren’t the cheapest around, but offer a lot of options in terms of practical use. Voltaic solar backpacks have a larger area for solar cells, which makes sure that maximum solar energy is stored in the pack. They also come with a battery.
This makes sure that any excess energy generated on a particularly bright morning is stored away and not wasted. Maybe the best part of the voltaic solar pack is just that: in case of rainy or cloudy days, it offers you the option of using power through your home sockets or your car’s cigarette lighter to charge the battery. This backup plan makes the voltaic solar pack very practical.
Solar Laptop Chargers. You will need serious energy to charge your laptop, compared to simpler solar phone chargers for example. And for this, you will either want to invest in a solar laptop charger, or a voltaic solar pack as described above.
Solar laptop chargers go a step further in being environmentally conscious since some of them are made from recycled soda cans. So we can see the appeal they might have for those of us more attracted to reducing our carbon footprint. As such, though, they do cost a bit more than the regular solar backpack and you will have to check with your laptop manufacturer to make sure you laptop will be able to charge from it.
Regular Solar Backpacks. These are for those of us who don’t really need the support system of a whole electronic office wherever we go. Regular solar backpacks generally have a lower capacity for power generation, and if your only requirement is charging phones, iPods, mp3s and so on, this is the best option for you. These packs are considerably cheaper than those that produce enough power to charge a laptop for hours. You will want to check for external battery though, in case you run out of power on a cloudy day.
