The Yellow Jacket is a pretty basic rubber iPhone case that snaps on to a larger attachment; it holds a battery pack and electric prongs. The device takes about four hours to get to full charge. After that, the Yellow Jacket can be used to double the battery life of an iPhone or zap a wannabe mugger about 50 times.
Nope, these aren’t the near-bezel-less phones that Oppo teased us with back in March, but they are still very compelling. Following the super slim R5, the Chinese company has shifted its focus back to specs with two new models: the 5-inch R7 and the 6-inch R7 Plus. For us, it’s really all about the bigger phone: its 7.75mm-thick aluminum unibody manages to pack a generous 4,100 mAh battery, which goes very well with Oppo’s renowned VOOC rapid charging — a feature that’s proven to be faster than most of its competitors’. Not to mention that the device also comes with a single-touch fingerprint sensor on the back, along with an 8-megapixel f/2.4 front imager plus a 13-megapixel f/2.2 main camera with an RGBW sensor (Sony’s IMX278) for better sensitivity in the dark, as well as laser auto-focus and dual-tone LED flash.
