The HYMini's miniNOTE is a thin solar panel/battery charger covered in brass-corner-reinforced recycled cardboard packaging. The packaging and manufacture both use practices to ensure a minimal carbon footprint. It is thin enough to fit into most mailboxes.
miniNOTE comes with a built-in 1200mAh Lithium Ion rechargeable battery, USB output jack and USB adapter tips for most of your 5V handheld devices. When completely charged, the miniNOTE can fully charge an iPod Nano or partially charge your cell phone battery.
Implications - It's always a great feeling to look in the mailbox and see a postcard a friend has sent you from a faraway land, and real postcards will never lose their charm, but solar postcards are the wave of the future, HYMini says.
The miniNOTE is available in stores now.
