Razer releases USB Type-C power bank for charging ultrabooks

Razer has announced a 12,800 mAh (46 Wh) portable Power Bank. Designed specifically to power the company's Razer Blade Stealth ultrabook via USB Type-C, it can also charge any other laptop that supports power-in via USB Type-C as well as other USB devices through it's dual Type-A ports. The Razer Power Bank will be available in March for US$150.

The Power Bank has a capacity of 46 Wh, meaning it should be able to recharge the Stealth to about 85%, or about 6 additional hours, according to Razer. That estimate should be even better on other ultrabooks with better power efficiency. The Bank itself takes about 2 hours to charge when plugged into a 45W USB Type-C adapter. 

The device is a svelte size for a portable power bank of its capacity, measuring 4.95 x 3.08 x 0.92 inches and weighing 0.74 lbs. The 12,000 mAh Dell power companion measures 7.9 x 6.2 x 1.6 inches and weighs 1 lb, albeit for a cheaper US$99.
