OtterBox has a solution to limited battery life. Today, the company revealed OtterSpot, its Qi wireless charging power bank, and stackable batteries. The OtterSpot Charging Base looks a bit like a thin hockey puck. It's designed to be stackable, meaning you can pile up to three puck-like OtterBox Wireless Charging Batteries and a device on top of it and charge all of them simultaneously. Each battery can then power any Qi-enabled device and support wired charging via a USB-C port. The battery packs come with 5,000 mAh of capacity and up to 10-watt wireless charging speeds.
