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.
Also i want to introduce another strong power bank with solar panel, GOAL ZERO SHERPA 100 KIT This medium sized kit is excellent for camping, hiking and other outdoor activities. The maximum power it can deliver is 120 watt.
