The Sanyo Eneloop range is always famous for its long-lasting battery life, and here we have with another Eneloop device known as the Sanyo Eneloop Solar Light. As you can tell by its name, it receives its power from the sun, outputting lights in arranged LEDs for rooms/emergencies by functioning as a flashlight. In addition, the USB port works great to juice up all your other phones and gizmos that rely on USB connectivity without letting you waste a single cent on disposable batteries as long as you rely on clean solar energy. Depending on the amount of lights used, this will release around 9 to 50 hours of light from a full tank.
