  • good product, but pay attention

    posted by Punkiderma

    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.
  • Fun to have.

    Compact & light. Cute. No battery required. Fun to have. You dont even have to own a business or retail store to own one :)
    I received a silver unit. It doesnt have the battery option. TIPS: Hold the rotating disk to make it stop spinning, let go and it will rotate the opposite direction.
    Get one (or more). It's fun. Your friends & guests will be amused.
  • works well - good value for money

    The unit is charged even if you forget to turn it off. No charge cable that hangs in the way. Holder is firmly attached with suction cups. Sound quality is more than adequate.It works well with my Samsung Galaxy SII."Boots" and connects to the phone very quickly.
    I will gladly recommend it to friends who want a simple handsfree car kit
  • works as it should

    -at normal conditions (in belgium) with no direct sun, it gives me 4V
    -in direct sunlight, it peaks at 5V (see cons)
    -in the shadow, it gives around 3V
    -quality seams ok (see cons)
    -solder point are marked with + and -
    I haven't been able to measure the current, but at I think it is aroud the stated 150mA.
    I use this to charge a (protected) 18650 cell. In 2 days it charges it completely.
    for this price u can't go wrong. It's probably a recycle, but who cares :)
  • handy piece of equipment

    output voltage is adjusted by potclean and well built PCBvery stable output voltage. With load or without it was exactly the same 12.15V while input voltage dropped from 4.14V to 3.86 after connecting fan.
    running PC case 12V fan from Li-Ion batteryin = 3.86V x 0.98A = 3.783Wout = 12.15V x 0.24A = 2.916Wefficiency in this particular scenario 77%no loadin = 4.14V / 22.3mA
    it works and does what says on a tin.
