    I bought them for $0.99, but seller is out of stock, the best offer so far is $1.55 :)

    12V car version for ~$5. Displays car voltage (12V), USB current, and temperature in Celsius. :(

    It uses very cheap step down circuit, so your phone/tab/whatsoever, will "enjoy" all spikes present in automotive environment :)

    The device uniquely combines mediocre parts with shoddy assembly without compromising any of the shortcomings of either.

    This LCD unit costs $4 but looks nicer, good for iPhone fanboys. Also tracks mAH and has battery & internal memory.

    Warning: This is not an "Over Unity" device since the cord appears too short to plug the USB input connector into its own output jack.

  • There's not a single photo on that entire eBay listing. It's all CGI. I'd be interested in photo of what you actually receive.

    Just had to beat Duane with this full house. 7 USB monitors, 3 different types represented.

    Now I can give them to my EE pals and die happy.

    Excellent!

    It's the real deal, PhiPi! The only negative thing to report is that it's not a sync/data cable as advertised. At least it doesn't allow the PC to recognize my LG Android phone. I can live with that to be the first on my block.

    Edit: Windows 10 downloaded a new driver today and it's working as a sync cable now with my same phone. Another Festivus miracle!

    Here's a different one, even cheaper: https://www.ebay.com/itm/Voltage-Current-LED-Display-USB-Sync-Data-Charging-Cable-Cord-for-iPhone-Samsung/123183328994

    The cable at that last link is REALLY nice. Feels like money, high quality, nice grippy rubber feel, has integral iphone adapter which can be cut off easily. The LED display is crisp. It goes out after a minute or two of zero current.

    Sadly, the erco effect remains after I purchased. Price increased from $2.68 to $3.35. I still got it!
