New battery gives up to four hours of runtime for Retina display laptops
Power solutions provider QuickerTek, has just unveiled an external battery for the Apple MacBook Pro line of laptops, including models with the new Retina display. The new EyeBattery adds up to four more hours of battery power to the MacBook Pro. Two models support either version of the MagSafe connector present on varying models of Apple's Intel-based laptops.
The one-pound machined aluminum device powers the laptop in parallel with the external battery through the user's MagSafe adapter -- the new line delivers a "use and charge" capability. The Li-ion battery elements are fully charged in 4 to 8 hours from the adapter, and feature compatibility with one of the company's Solar Juicz solar power chargers. The battery is rated for 56 watt-hours.
The New EyeBattery retails for $300 regardless of which revision is desired. The battery is available at select retailers and online now.
