Millions of traveling gadget lovers tote around wall chargers, adaptors and converters to ensure their favorite electronics -- such as mobile phones and MP3 players -- are powered up and ready for action.

The Powerstick V2 by Ecosol looks to be an easier and smaller alternative. This tiny USB-based device charges up using a computer's power and includes nine different adaptors to power many popular portable devices, including smartphones, iPods, digital cameras and Bluetooth headsets. The company claims that this small doohickey can double talk time or audio playback.

About the size of a small pack of gum, this device takes up to 90 minutes to power up its internal Lithium polymer battery (to 90 percent) from a laptop, airplane seat or compatible car stereo, while a small LCD “Fuel Gauge” on the screen displays its charging progress. Connected devices can be used while the Powerstick is charging.
