QuickerTek's 2015 Type-C MacBook External Battery (http://tinyurl.com/omewbse) for Apple's 12-inch MacBook with Retina display charges the MacBook for eight extra hours of run time.

This battery features the USB 3.1 adaptor cable necessary to power and charge the 2015 Apple 12-inch MacBook. Users of the newest Apple laptop are no longer confined to powering and charging their MacBook only where a power outlet is available.

The US$2.99 battery's base unit utilizes the highest charge density of Li-Ion polymer batteries available. It also includes a light weight 3D case, allowing QuickerTek to custom build the battery in any size. PCM and Smart Charging protection is included in the design so cells won't overheat, over or under charge. 

Another exciting quality of this battery is the way in which the user can check its charge status. Instead of LED indicators, this battery includes a button which can be pushed by the user, and the battery will send a message via Bluetooth 4.0 LE to their iPhone, iPad or MacBook displaying the charge status. 

It can be recharged via the 30 Watt 2015 Type-C MacBook Solar Panel from QuickerTek. You can use this product in conjunction with QuickerTek's new 30 Watt 2015 Type-C MacBook Solar panel, as well.
