Receiving postcards with pictures from exotic places is fun, but you know what’s even more fun? Receiving a solar postcard. HYMini’s miniNOTE is an ultra-lightweight portable universal power bank that fits into almost any mailbox. The miniNOTE comes complete with a built-in 1200mAh lithium ion rechargeable battery, USB output jack, and USB adapter tips for most 5V devices.
The miniNOTE is wrapped in recycled cardboard packaging along with brass metal corners for durability. And HYMini’s device packs quite a punch for its size— when fully charged, the miniNOTE can power an iPod Nano halfway.
I haven’t seen pricing information on HYMini’s website, but I’m guessing the miniNOTE won’t cost more than $25.
