Charge Your Cell Phone With These Human-Powered and Solar Chargers
The cell phone has pretty much become a necessity in this day and age, and you can’t get far with a dead battery. There are, however, greener alternatives to plugging your phone straight into the wall or computer, and they can also come in handy when travelling or during a power outage or other emergency.
The Solio Classic 2 uses the sun’s energy to power up any USB device. With its own built-in battery, it can hold a charge for up to a year, making it useful even when the sun isn’t out.
The nPower PEG uses kinetic energy from walking, running or biking to generate power that can be used to charge up thousands of compatible devices, making it a great option for hiking trips or those who like to walk or bike to work.
The SOSCharger is also human-powered, using a more traditional hand-crank method to charge cell phones and other small devices. It also powers a built-in flashlight, making it ideal for use in emergencies or while traveling.
