When you're on the road, you want to make sure you can stay connected, but you probably have more than one device that will need to recharge. With the Powerbag Instant Messenger Laptop Bag, you can keep your devices charged without worry. The bag features a built-in charger and removable battery so you can keep your smartphone, tablet and e-reader powered up. It comes with built in Apple, Micro-USB, and Mini-USB connectors, as well as a USB port, so there shouldn't be a device you can't keep charged. The bag itself features a waterproof charging port as well, so you won't have to worry about getting caught in the rain and ruining its charging capabilities. If a messenger bag isn't your style, you can choose from a number of options, including a rolling office case or backpack.
