Laptop Power Bank 27K

The 27K capacity is a lifesaver on back-to-back client meetings—I charged my ultrabook from 15% to full during a two-hour train ride and still had plenty left for my phone overnight.

Charged my MacBook from 20% to full while I was working at a coffee shop, and still had plenty of juice left for my phone. The 27K capacity is exactly the kind of buffer I needed for long travel days.
