The wireless dock is small and compact - about the size of Pringle's potato chip can - so it's easy to snag for a picnic, a trip to the pool, or a short walk to your favorite lounge chair.
It's also easy to pair with any device that supports Bluetooth, including iPads, iPhones, and Android devices. And it plays nice with an iPod, a TV, portable DVD player or any other non-Bluetooth device by connecting a stereo cable to the gadget's headphone jack.
Because the dock doesn't have a standard Apple plug, it won't charge your Apple device. But it does have a handy groove that holds an iPad or a mobile phone. The dock's amplifier is powered by a rechargeable battery that gets refueled through a USB cable. I've played two hours of music and video without exhausting the battery.
The sound from the dock's tiny speakers is crisp and clear and loud enough for background music at the dinner table. Don't count on it to light up a large room or a big back yard.
The Coby CSMP135 has a list price of $49.99 but you should be able to find it for about $10 less at several online sources.
