Keeping a cell phone charged when traveling long distances can be a challenge even emergency charges don't last that long, so what can you do. Medis Technologies has come up with a Fuel Cell Power Pack that can keep your mobile devices going for a long time. It's the next best thing to having an actual wall outlet with you at all times. It is very compact and disposable, only the size of a soap bar and weighing only 5 ounces. The fuel cell can deliver up to 15 to 20 hours of power allowing most cell phones to have about 30 hours of talk time, plus the cost is fairly cheap, costing only $20. Now you can drive to those vacation spots or business trips without worrying about losing power on your cell phone or other mobile devices.
