External battery packs are a dime a dozen, but you might want to pay attention to this one. Razer has unveiled the Power Bank, a 12,800mAh external battery designed primarily for laptops. It's clearly intended as a companion for Razer's own portables, and can extend the life of a Blade Stealth to as long as 15 hours. That's more than a little helpful if you're stuck traveling all day. However, its reliance on USB-C makes it compatible with any laptop that can charge using the newer connector. Yes, you could keep a MacBook running on this brick if you don't mind the style mismatch.
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.
