We like sexy, and slim. And Cabin from Hevo Labs is an incredibly well designed aluminum battery, charger and dock for your iPhone. Cabin magnetically attaches to your iPhone, drastically improving the recharging experience.
Cabin may just be the easiest way to recharge your iPhone. It is currently backed on Kickstarter and should start shipping this Fall. It also appears they are already designing the next version of Cabin that should be compatible with the iPhone 6.
