There's always a must-have hot new gadget debuting. Many of these items put the fun in their sleek and sexy

functionality, but the majority of them require power to run. As a busy traveler short on time, how can you ensure all your devices stay juiced up? The options might not be as limited as you once thought.

Consider the sun - or more specifically, the benefits of solar energy. A hybrid versatile charger from Solio (1)is able to charge itself solely off of sunlight (but also from an electrical outlet). The Solio Classic can store energy in its internal rechargeable battery for up to one year. It can charge anything - from a cell phone to a PDA to a GPS to an iPod. One hour of sunlight provides 20 minutes of talking time on a cell phone or 50 minutes of mp3 music playing. Performance times may vary, depending on the intensity of the sunlight and the device being charged. The Solio Classic retails for $99.95; is available for purchase on its website; and comes in four colors - white, black, pink, and standard-issue silver. Also check the device compatibility page (2) to purchase the proper connector tips and cables to charge all your devices. Alternate models include the Solio Hybrid 1000 and the Solio Magnesium Edition.

Another eco-friendly option is the Noon Solar bag, which is made of sustainable fabrics such as hemp, cotton, and chromefree leather (3). A paper-thin, flexible, solar-powered strip on the outside of each bag absorbs sunlight to retain power. Each bag also contains a battery pack (known as a power bank) that should be charged in a wall outlet before use to ensure a full life. Once the power bank is connected to the solar panel, it takes six to eight hours of sunlight to charge completely. Fully charged, the power bank will provide at least one full charge of a device, depending on the device's size. The bank will retain its charge for a few days if not in use. The bags are both waterand weatherproof, and retail at multiple locations listed on the website (4). Prices vary, with the Cortland design costing $383, while the suede Willow design sells for $274.

Other solar-power products include Juice messenger and beach bags, backpacks, and portable flexible solar panels from Reware (5). They retail between $149 and $399.99. Voltaic Systems also provides bags and backpacks (6), which cost between $199 and $249.

A notable standout is the new Voltaic Generator laptop bag. The only one of its kind thus far, the Generator can retain up to 14.7 watts, which is enough power to charge a laptop. The bag retails at $599, and fits up to a 17-inch Powerbook. All Voltaic bags are made out of PET - a lightweight, durable, and water-resistant thermoplastic material made from recycled soda bottles.

Finally, the Philips Power4Life series (7) will debut soon. The Power2Charge universal SCM7880 USB adaptor has six different outlets and provides up to 15 hours of charge for devices up to 5 volts. In addition, the Power2Go SCE7640 portable USB adaptor provides up to 60 hours of charge for devices up to 21volts (which is equivalent to most laptops).
