An ideal source of clean energy for charging Eneloop rechargeable batteries, relying entirely on solar power instead of a conventional power supply. After the unit's internal lithium-ion battery is charged from regular exposure to sunlight, use the unit for a quick recharge of Eneloop batteries or as a source of power for electronic devices via a USB connection, as needed. Simply by setting the charger down on different sides, users can catch sunlight from two angles, accounting for different positions of the sun each day, throughout the year, or in various locations. Simple in design, the unit is shaped like a pyramid, which is practical. In this way, the design reflects its purpose and fits in well in home environments.

Offering a new style of recharger encourages more people to try Eneloop rechargeable batteries. It is an easy way to be more environmentally conscious and make a difference. We were committed to a form that is natural and not too imposing. It is a familiar, unassertive shape.

Rechargeable, reusable batteries represent a new phase in development for the Eneloop series, highly acclaimed as communicating Sanyo's eco-friendly corporate philosophy through a platform of innovative technology. One application of this technology is this solar recharger for Eneloop batteries, which epitomizes clean energy. Functional and attractive, the pyramid can be repositioned to catch the sun at different altitudes from two angles. It can be used to power and recharge external devices via USB. This device, as well as a USB-powered recharger, a battery-powered reusable hand warmer, and a cordless warmer (an alternative to electric warmers) are part of an innovative product line that demonstrates eco-friendly corporate ideals at a high level, in forms that convey these concepts. The project is also quite admirable as design that helps redefine a corporate brand. [Hitomi Sago, A02 unit leader]
