PE3W-BT Rechargeable Portable 2x3W Bluetooth Amplifier
The PE3W-BT portable Bluetooth amplifier's slim design enables it to be mounted in small spaces and deliver quality sound. The NSIWAY NS4250 Class D Stereo amplifier board puts out 2 x 3 watts @ 4 ohms and can handle up to an 8 ohm load per channel. Its small size can be mounted in small toys, ornaments, small displays, and music boxes with unbelievable sound for its size. It can turn small forgotten about bookshelves speakers into great sounding, portable Bluetooth speakers.
This portable Bluetooth amp accepts standard speakers or exciters that are 4 or 8 ohm and accepts 5 VDC as a charging source. Small exciters will even stick to the amps black plastic housing to create out of sight sound. You can stick exciters to larger pieces of plastic, card board, foam core board, and hard board to achieve a fuller sound. This amp just needs a charge from a USB adapter that comes with most cellphones. It includes a mini USB cable that plugs directly into your USB A wall adapter or directly into a computer USB port. It works while charging, but charge time will be extended. Just add speakers and young or old will enjoy making the ultimate sound project.
One quick project is a wireless microphone. Just add speakers or exciters to the PE3W-BT Bluetooth amp and download a Bluetooth microphone application to your smartphone or tablet. Then put the Bluetooth amp and speakers into a tissue box, Jack-o-lantern, or toy and throw your voice wirelessly up to 30 feet away from the amp. Disguise your voice and speak into your phone and people will think that your project is talking.
The 550 mAh battery delivers true portable sound for up to 8 hours of easy listening back ground music, or crank-it-up all the way and rock out for 2 hours on a full charge. It takes a minimum of four hours for the battery to get a full charge from a 500 mA USB charger.
