Like some of these batteries, the Power Bank doubles as a phone charger thanks to two USB-A ports. It even supports Quick Charge 3.0 for those phones that can handle it. This definitely won't be an inexpensive peripheral when it ships in March, at $150 (£170) -- we've seen higher-capacity batteries that sell for less, like Mophie's Powerstation XXL. Not all of those are designed to charge your phone and laptop at the same time, though, and the logo-emblazoned aluminum body might be worth it if you're a dyed-in-the-wool Razer fan determined to coordinate the look of your gear.
