Like most business travelers, I travel with plenty of power-hungry devices, like iPhones. But what frequently happens is a get close to running out of power. And when I do, it's usually just when I need it. I usually travel with lots of power chargers for hotels and cars, but when I'm out and about or in meetings, I don't always have a chance to use a power charger.
A great solution for this type of problem is to have an external, rechargeable battery pack. External battery packs allow business travelers to easily recharge electronic devices whenever and wherever they want.
The fatcat PowerBar is one good example of an external travel charger that provides enough power for a solid recharge for devices like an iPhone. The device is about the size of half a pack of playing cards. It's slim and light and fits easily in a pocket, briefcase, or suitcase. The product is mostly black with a silver front. It looks professional and slim.
The PowerBar is also simple to operate. There's only a single button on the front of the device to start charging. Blue indicator lights show when the battery is fully charged. The device also has a port on either side, one for input and charging via a USB cable, and one for output, for charging phones and other devices.
