Ask Slashdot: What Interesting Things Can I Power With an External USB Battery?

New submitter expert464 writes: I just purchased an external USB battery for the main purpose of charging smartphones. I've also thought of using it to power a USB lamp and charge a bluetooth speaker. What other things am I missing that would be useful and/or interesting to power when not near an electrical outlet?

    Low-power amateur radio is always fun, especially backpacking where portable power is nice.

  2. Picture Frame by gunslnger · · Score: 5, Interesting

    I use mine to power a digital picture frame so I could actually hang it or place some place that having a cord to it would look bad.

  3. BlinkyTape or a similar LED installation by kav2k · · Score: 3, Interesting

    You could look into LED decoration. For example, BlinkyTape - a LED strip with an attached Arduino-compatible controller.

    It can be just decoration, or you can use it for light painting.

    Of course, you can build your own LED-based contraption.
