Blurring the line between phone and battery pack, the Energizer P18K Pop is a gargantuan gadget only the company's drum-beating mascot could love. Nearly three iPhones thick, this hefty mobile has an 18,000 mAh battery inside — good for two straight days of video consumption and nearly two months of standby time. Its 6.2-inch 2160x1080 display is almost bezel-less thanks to a pop-up dual-camera selfie setup that complements the triple camera array on the back. It also offers 6GB of RAM and 128GB of storage, but let's be honest: battery life is the only reason to consider cramming a device this large into your pocket.
