If you like to go out into the country for picnics with the family, or if you like to go fishing with friends, you would boost your enjoyment by taking along this Rechargeable Bluetooth Speaker. This powerful little speaker runs off rechargeable batteries and can run for five hours of continuous play. It has a USB port into which you can plug a memory stick, and there is an SD slot to take a memory card. There is also a 1/8” AUX socket, by which you can connect the speaker outlet of your MP3 player or iPod, so you are not limited to the radio as a source of music. It comes with a handy shoulder strap, making it easy to carry and it also has a headset with a mic. These features mean the speaker works well as a portable PA system, for example, for a park ranger, or for an event marshal.
