Review on CestMall F10 Portable Compact Mini Speaker - Four Times the Normal Volume - 3.5MM Audio Input - iPhone Android Tablet Nevigation PSP MP3 MP4 - Black by Jennifer Ford

This little speaker was recommended by an amateur friend for use with QRP receivers. It plays the sound about 3 times or more. When I use headphones only I can listen, but just plug in this device and the band hears it. The instructions are in a different language, but all you need to know is to press the bottom to turn on/off. The charging socket is covered on the side with an elastic band. I use it with my netbook and QRP ham. You get a very nice case that has room for the speaker and all the necessary adapters. This is perfect for my needs.
