  • just received my one of these, fast delivery, well packaged too.
    very happy with it. my bike lights run on a pack of li-ion 3.7v batts in series (10,000Mah)that are hooked up to a solar panel.
    now with this added to my solar panel/battery box, i have USB 5v out to power my phone or my Bluetooth MP3 player that sits in my GPS/phone holder mounted on the handlebars!
    previously i would use my smartphone as a GPS device when navigating, or have my Bluetooth MP3 player in the holder, and now i can have them CHARGE while i use them!
    great stuff.

  • is this pre-assembled or a kit?
    this will be my 1st purchase here and i don’t see any clues anywhere as to if the products are self-assembly kits or pre-assembled products.

No public wish lists :(
