A Must-Have Green Gadget: The Portable Solar Laptop Batteries Charger

Solar panels may be able to turn any light into electricity, but the time required to completely charge a device is directly related to the brightness of the light source. The downside of solar power isn't a dependence on sunny weather, therefore, but rather one's willingness to wait upwards of 8 hours for a device to completely charge (and that's in direct sunlight!). To remove some of the solar charger's unpredictability, newer models come with a reserve feature (in the form of a lithium-ion or lithium-polymer battery) that collects, processes, and stores electricity obtained from either a light source or an alternative power source, such as your car or laptop batteries. While the battery emphasizes the solar charger's adaptability, it lessens the gadget's environmental accountability, since it will need to be replaced in about a year and throwing out batteries isn't exactly green. It's important to read the product descriptions when you're shopping and comparing portable solar chargers, however, because not all "universal" models are compatible with the electronic devices you own or plan to purchase. It may not be a wise purchase for everyone, but in case of an emergency, in place of a power adapter, or as a part of an eco-friendly travel plan, the portable solar charger makes it possible to be a little greener on the go.
