Massive portable battery pack means you?ll never run out of juice (Yahoo! News)

The Yill can provide days of power on a single charge

Running out of power for your mobile devices is an extremely frustrating experience. Extra?battery packs can help, but their practicality is limited due to the relatively small amount of extra energy they provide for more power-hungry devices like laptops. Germany energy company?Younicos believes it has found the solution to these problems with the?Yill, a portable power storage unit that boasts an extraordinary amount of flexible energy.

After a relatively short 4-hour charging session, the Yill's lithium-titanium internal battery can power a normal computer workstation for up to 3 days. Using sleek built-in wheels, the Yill can be rolled just about anywhere, and can completely eliminate the need for local power outlets in workplaces where it can be charged overnight. Its futuristic form factor was conceived by German furniture designer?Werner Aisslinger.

Unfortunately, despite being portable, the Yill's huge storage capabilities are thanks in large part to its generous footprint. You won't be tucking the unit under a tiny desk or neatly placing it on a shelf, it's simply too large. Still, for three days of workstation battery life, it's undoubtedly a cool office accessory.
