The group used a Kickstarter campaign to raise $200,000 for production of the charger. That goal was met within 24 hours, with 1,000 early backers getting in at $79. The Dart will eventually go on sale for a retail price of $120. Act fast, though, and you can pick one up in blue, magenta, silver, black, or orange for $79 or $89. U.S. shipping is expected to begin later this year.
