Ah, summer in the Midwest. Nothing's more fun than sunburn and mosquitoes and 90 degrees with 90 percent humidity-unless, of course, you count the thunderstorms that can knock out the electricity (and the air conditioning) at any moment. After a handful of surprise power outages and disappearing unsaved work, I finally figured out that I didn't have to subjugate my image editing to Mother Nature's whims. I purchased a UPS battery backup from APC, so now when lightning strikes, the lights may go out but I can keep on working-at least long enough to make sure I save all my changes and shut down the computer. It has enough outlets to power my computer, monitor, external drives, printer and speakers, so I can I can keep workingâ¦ or just watch Web videos while the food in the fridge goes bad. But if you are out in the field, luckily there is a website that offers a variety of options to keep either your laptop or digital camera running, too. The Battery Geeks (www.batterygeek.net) offer a variety of external batteries for all sorts of devices, the PowerStick15 in particular keeps iPods, PDA's, and even digital cameras running. If you're using a laptop, they have different external laptop batteries that will lengthen the life of your MacBook Pro, or various other models. Visit www.apcc.com or www.batterygeek.net.
