We live in age where at any given time a person can have upward of six chargeable items on themâ€”from cell phones, PDAs, laptops, tablets, iPods, and so on. However, a power outlet is not always readily available to for the person on the go. This PowerBag messenger by Ful solves that problem with their built-in PowerVine system, which consists of connectors for Micro-USB, mini-USB, and Apple Dock devices. It also contains a normal USB port to charge any device that doesnâ€™t fit the aforementioned connections. Thanks to a built-in rechargeable 3000mAh or 6000mAh battery, the PowerBag can recharge up to four devices at once (one of each connection type).
