Razer is releasinf a sleek-looking Razer Power Bank external battery, a 12,800mAh battery which can help a Blade Stealth ultrabook stay alive for as long as 15 hours, or power your USB-C-powerd device.

Razer says that the new Power Bank is optimized to work with the Razer Blade Stealth 12.5-inch laptop to extend battery life past 15 hours.

But the external battery is also compatible with additional USB-C powered laptops, such as the Dell XPS 13, the Asus Zenbook or the Apple MacBook. Users can also connect a wide array of mobile devices with dual USB-A ports and a USB-C port for charging up to three mobile devices simultaneously.

The Razer Power Bank is equipped with Intelligent device charging and is able to instantly identify the type of device that is plugged in. A fast-charge feature unlocks up to six hours of battery life in a Blade Stealth in less than two hours of charging.

Additionally, Qualcomm Quick Charge 3.0 allows users to power up their compatible mobile devices up to four times faster than conventional charging.

The Razer Power Bank is small enough to fit in most pockets. The accessory is available in March exclusively at Razer Store for $149.99.
