    Involvement Level: Expert (understands the inner workings)

    Pros: It does a great job of adjusting the input to any desired output voltage. Fine design, so it could be build into any project. Good build quality

    Cons: Not usable on my solar panel (I bought one that you could hook up to your car. But i needed the panel on a not so bright place, and tried this as a solution) Even in the brighter test conditions, i could not get this to work. I found a solution that works on my solar panel, so the solar panel is not at fault. When i hooked up this device to a power supply, it did a great job of giving a steady voltage, therefor I recommend against this as a solution for solar to power.

    Other: Not a great solution for solar power conversion. A great solution to build an adjustable power supply.

  • seems to be very precise and accurate but...

    Involvement Level: Expert (understands the inner workings)

    Pros: The selected output voltage (14.4V) is very stable when providing any voltage from 4 to 15V. The pot-meter is easy to adjust. Have not tested it with any loads yet.

    Cons: I could not get it to work on low-current power supply (solar panel). I misread "rated input current" as something nominal. I suppose this should have been the minimal current the power supply should deliver.

    Other: Seems to work great when keeping to the specifications.

    Involvement Level: Expert (understands the inner workings)

    Pros: Step up AND step down. Efficient, no heat loss. Indicator light when working. Screw terminals in and out, good markings +/- Accompanying spacer nuts and bolts makes installing in metal encasement a breeze. Good build quality.

    Cons: None that I have found.

    Other: Great for variable input power sources, charge your phone from your bike dynamo, maybe? (rectify first) I have bought several, and they work as advertised

  • OK, but not for solar panel

    posted by Alexketto on 04:06:29 G12T 10/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Excuse me, for my english. Good construction. No other parts needed. Fully adjustable output voltage within the specified value.

    Cons: This solar panel can not be used because of low internal resistance to completely overload the solar cell, the solar cell voltage drops to 1-2 volts on which this module is no longer working, so there is no output voltage. The solar cells in current generator mode, the internal resistance is so high.

    Other: Good, goog, but the Solar Power Supply?
