There are a lot of Bluetooth wireless speakers to choose from, so it's always interesting to see one that has a few tricks up its proverbial sleeve. Such is the case with the water-resistant HR-903 Wireless Speaker ($129.99) from Turcom. Of course the battery-operated wireless speaker offers serious sound thanks to the 30 watt speaker with extra emphasis on bass, but it also includes a USB port. This allows you to charge your iOS (or Android) device using the speaker's built-in 8,000 mAh battery. If you just use the battery for music, it should last about seven hours.
