Until smartphone batteries last for weeks on end, carrying a backup charging cable wherever you go will be a necessary evil. But at least you don't have to deal with a perpetual tangle of wires if you import SoftBank's new Itomaki AC Adapters. They're shaped like a thread spool letting you wind your cable around so it's always neat and tidy.
Available mid-June with a Lightning connector for the iPhone 5, the Itomaki will come in a series of subtle pastel colours for around $36. A 2.1 amp version for the iPad will be available a little later in July, while a microUSB version is also on the horizon, but with an unspecified release date. Hopefully it won't be far behind; there's nothing as exciting as a spool used to prevent knots instead of creating them. [SoftBank via Akihabara News]
