Bacteria be gone
SteriPen'slightest water purifier yet, theAdventurerOpti weighs a mere 3.6 ounces. Using ultraviolet light, the hand-held device quickly zaps 99 percent of viruses, bacteria and protozoans that cause waterborne illness. A newly insulated tip allows it to purify even the coldest of water, say, from a mountain stream. Another new trick: The device doubles as an LED flashlight. steripen.com, $99.
Everything in its right place
Instead of having one cavernous compartment that swallows your stuff whole,Ivar's day packs use semi-rigid dividers to redistribute the weight, keeping your items from clumping at the bottom in an indistinguishable mass positioned to wrench your back.

Seeing is believing

Know where you go
Panasonic brings built-in GPS to its vaunted line of Leica-lensed cameras in the Lumix ZS7, which geotags each photo and video with precisely where it was taken.

The lens options for zooming range from superwide to tight close-up. , $400, lens included
Luggage locator
If you're tired of jockeying for a spot at the baggage carousel and battling fellow fliers over similar-looking luggage, let your bag find you instead.

Press a button, and when you step within 90 feet of your bag, the fob alerts you by vibrating, ringing and flashing. , $25.
Cut the cord(s)
Powermat's Portable Mat wireless charging station allows you to charge devices such as your phone, MP3 player, iPhone, BlackBerry and Bluetooth headset without their adapters, so you can leave the tangle of cords at home. Instead, connect a tiny Powermat receiver to each device, and place it on the mat to begin charging. The only cord involved is the one running from the wall outlet to the mat, which folds up into a nifty packable case smaller than a Harlequin romance novel. , $100.
Airtight solution

Fly to the music

Max out your allowance
How gleeful it is to wrestle a bulging bag onto the scale at the airport check-in counter and watch it tick right up to the very limit of the weight allowance — and not one ounce more? Balanzza's new Mini luggage scale is shaped like a handle, with a strap that hooks to your belongings, so it's compact enough to take anywhere.
