Two photography enhancements for smartphones: • Ztylus Revolver Lens and iPhone 5S Case: The Revolver Lens system adds wide-angle, fisheye, macro and circular polarizer lenses to your standard iPhone photo capability. To switch from one lens to another, you simply rotate the lens turret to the proper position and gently push the lens of choice into place. The Ztylus system, with its ground-glass, multicoated lenses, combines the convenience of a smartphone and the versatility of a stand-alone camera. The system, with a polycarbonate-and-aluminum case, is also available for the Samsung Galaxy and Galaxy Note. iPhone case (black or white), $40; lens attachment, $70; www.omegabrandess.com. • Olloclip 4-in-1 Lens system: Designed for the iPhone, this quick-connect lens solution literally expands the horizons of your smartphone photography by enabling you to easily add fisheye, wide-angle (great for travel photography), 10X macro and 15X macro lenses to your device's optics. A separately priced telephoto lens and circular polarizing lens are also available. The Olloclip uses ground, coated glass for the lenses, while the barrels are made of anodized aluminum. Taken together, the lenses can easily fit into a pocket or purse. Also available is a Quick-Flip case for the iPhone 5/5s and 4/4s that features a corner that rotates so a lens can be attached while at once serving as a handy shutter release. Included with the case is a removable tripod mount. 4-in-1 Lens System (lenses, caps, bag, iPod Touch adapter), $69.99; with case, $99.99; www.olloclip.com. Magellan RoadMate 6230-LM GPS: This device combines full GPS functionality, including free map updates (U.S., Canada, Puerto Rico), traffic cam alerts and landmark guidance, with an integrated, forward-facing dashboard cam that can be used to document landmarks and, more importantly, review and record the event immediately preceding and following a car accident. The video footage, which can be saved, captures a 120-degree-wide viewing angle. Once a video is locked, it can be replayed on the device itself or on a Windows-based computer. As a personal GPS, the Magellan Navigator boasts a 5-inch screen, 7 million points of interest, 4 GB of storage, turn-by-turn instructions, spoken street names and landmarks and a number of other useful features. $229.99; www.magellangps.com. In light of the TSA's recent ban on dead batteries on some international flights, consider the following portable power supplies for use when traveling: • MyCharge RazorPlus: This sleek battery pack, housed in a slim, anodized aluminum case about the size of a cellphone, provides 13 hours of talk time, a high-density 3,000 mAh battery promoted as shortening charge time by 25%, a four-light LED battery life indicator and pass-through technology that enables the RazorPlus and your device to be powered simultaneously. $49.99; www.mycharge.com. • Jump Cable: At once a charging cable and a power booster with a lithium-polymer battery, this product, according to its manufacturer, provides 30% extra charge to an iPhone and up to three hours of extra talk time while weighing only 1.4 ounces and measuring a meager .53 by 1.96 inches. The cable, when unfurled from its housing, stretches a full 19 inches. Compatible with either Lightning or micro-USB connectors. $49.99; www.bitemyapple.co. • Justin Power Stick Travel Pack-Up: This compact travel kit has everything you need when you are on the go: a 2,200 mAh power stick, a car adapter, wall charger and micro USB cable. The power stick itself, small and slim enough to fit in a shirt pocket, has a universal USB output port, micro USB input port and can recharge a smartphone from completely drained to fully charged. A zip pouch that holds all the components is included. $29.99; www.ithomeproducts.com. Vertty Beach Towel: There is still plenty of warm weather left for this product from Portugal, a designer beach towel that is distinctive in several ways. For starters, it is 4 inches longer and 30% lighter than most other beach towels, dries faster and has a waterproof pocket to safely house, for example, your smartphone. The towel, which has a zigzag design and comes in nine color choices, is made of a fabric that is 90% cotton and 10% polyester. Vertty maintains that all chemicals and textiles used to produce the towels, which are handmade, are ecofriendly under Oeko-Tex standards. $89.90; http://us.tryvertty.com.
