Seems like many accessories you buy work for only one device, and you have to buy all new accessories when you change devices. Kensington is eliminating that need by offering some universal smartphone accessories. The Pocket Battery for Smartphones (center, $39.99) is a rechargable battery pack that can extend your battery life by up to 3.5 hours. It has built-in mini and micro USB charging cables so it can work with a variety of smartphones, including Blackberry®, Nokia®, Motorola®, Samsung®, HTC®, LG® phones. There’s also the USB Car Charger (bottom right, $9.99) that provides 1 amp to charge your Blackberry or any other USB powered device. The Windshield/Vent Car Mount (bottom left, $29.99) is adjustable to hold a variety of smartphones within easy reach – it even fits when the smartphone is in a case. Finally, you can connect your smartphone to the AUX port in your car’s audio system to play your music. The AUX Audio Cable (top left, $9.99) lets you connect your smartphone or other device to the Aux input in your car audio system. The Noise-Reducing AUX Audio Cable (top right, $19.99) reduces hum from your car’s electrical system to provide cleaner sound. You can purchase these accessories directly from Kensington or Amazon.com.
