With Texans along the Gulf Coast recovering from Hurricane Dolly, we thought it would be a good time to mention electronics gear that can be invaluable to have before, during and after a natural disaster or other emergency. Of course, there are other items you'll need, such as flashlights, water, and more. For a complete checklist and other tips on preparing for—and dealing with the aftermath of—devastating storms and disasters, see our free Storm and Emergency guide on ConsumerReports.org.

On the electronics front, here's what we recommend:

• Make sure you have an emergency radio—powered by either batteries or a hand-crank—which will work even if the lights go out. A radio can pull in vital news, weather, and evacuation information from AM radio stations, which have further "reach" than TV broadcasters.
• Have at least one corded phone that doesn't require electricity. A cordless phone's base station won't run without juice.
• Keep your cell phone charged and have alternative power options—a car adapter or a portable cell phone charger that uses common AA batteries or features a hand crank or other "green" energy source.
• Consider having family members use different cell phone service providers in case one carrier goes down.
• Know how to text message. If cell towers are still up but available bandwidth is limited, a text message may be able to get through when voice calls won't.
• Learn how to browse the Web on an Internet-enabled phone. You'll have news bulletins, maps, and more at your fingertips.
• Have a portable GPS navigation system, which can be handy if you have to evacuate through unfamiliar routes and areas.
