  • Good if you know how to use it.

    posted by BobEast

    Very small footprint for mounting in a project. Easy to wire, and works great off an Arduino power pin. When wired to a 4ohm speaker, amplifies the signal nice and loud. Great price, other places sell this unit for $15 or more.
    a small wiring diagram would be useful. There are some pictures online of how it can be wired.
    Good for making your audio loud, but requires an external volume control.
  • good product, but pay attention

    Small, with matte finish that helps to catch more solar energy.
    If you want to use it for small things (leds, small electronics) I think it would be ok, but pay attention to electronic device that absorb more energy.
    For the price, I think is a very good product. Very easy to use and mount. I think you’ll need also a voltage regulator to use it at his best.
  • Works like it should

    Easy to use. Works as advertised. Nice display of battery life. Small. Easy to solder leads to. Have used it with a few different batteries from 900mah to 4400 mah and it has worked fine.
    I'd recommend it to anyone who likes to build their own. I will be ordering more to build my own set of rechargeable heated glove/shoe inserts.
    If you need it, get it.

  • amazongly powerful and good sound quality

    posted by adjevanhethof

    - very low energy consumption on idle- good build quality: PCB is properly assembled with goor quality components- good sound quality, no quiescent noise, distortion or other audible artefacts. Frequency response is good also, deep powerfull bass and clear high.- powerfull sound, already starting at supply voltage levels from 8V.
    this is a great little amp that can be directly hooked up to an Ipod, mobile phone or media player. The potmeter has a smooth control and adapts for the typical output levels of these devicesI have combined the amplifier with a Bluetooth stereo receiver module and a Li-Ion battery pack, all available from DX, powering a set of old car speakers. This setup makes a great wireless boombox with lots of power and great sound quality, comparable with the ones that cost hundreds of dollars.
    great value for money and quality component.
