  • Very Nice Item

    Reasonable price. If your looking for a Constant voltage power supply? this is certainly not a bad deal. It does what it states. Also interesting to know is you it has a dial on it so you can adjust the voltage down to approx. 11.1 Volt. Seems rather unimportant, but it often is useful to limit voltage a little bit lower than 12 volt. The same way you can beef it up to +13V if you ever want to challenge your LED's ;-)
    Be aware it isn't waterproof (obviously, but never the less). Although it's pretty good caged and shielded, one must be aware that 12Volt and 220V are sitting pretty damn close to eachother. A mistake is easily made. Better would be to have them separated at different sides.
    Does what it should do. Deliver a constant 12 Volt.
  • Neat little power pack for hobby projects

    Sturdy stainless steel housing, small size allows you to place it inside equipment. Neat printed circuit layout, good component placement and soldering, looks really professional. Little green LED indicates power is available.
    No user documentation is supplied but that is not really needed for standard use.
    Good value for money, neat little power pack for hobby projects.
  • Very good

    Small easy to fit in a 4"x4" box and it is still room for wiring
    It has a 5 second delay from turning the power on but that is not a big deal.I am using it for indirect LED lighting at the ceiling and it is placed on a motion sensor The connectors should have some kind of protective cover just in case anything gets loose over the time because the heat for safety reasons
    Good buy definitely i will buy more if i need it to do more projects like this one!

    It can operate as an energy source for people with more casual than a notebook. Easy to use, can be used in car comes with cigarette lighter connector, there are 13 connectors for easy adjustment, the good that he does not need to manually adjust the voltage setting is automatic in some very good this.
    The product is good meets the needs might be a little cheaperEasy use at home or in the car meets the needs wherever you are.
  • A good converter with good parameters.

    The device is good at laptop powerful loading (> 50 watts). Heating is negligible. Efficiency as declared. The minimum input voltage was lower. Device to run with 9,6 V, but with low efficiency.
    Solid capacitors, probably would have been better, and slightly increased the cost of the device.
    The unit deals with the task. With proper cooling, can work on the stated power (150 watts). I would recommend using it on a constant load up to 100 watts.
