dc power supply Customers Reviews

  • Easy-to-use item

    posted by Toxin65

    - rather cheap- handy- separate channel to measure voltage, using internal voltmeter- convenient output cables
    Great item for the price. There's much free space inside the shell, so you may add some features if needed. RF detector works fine.
    I'm glad I have this one in my lab. It does, what it's made for. Especially recommended for beginners.
  • Good universal 100w laptop power supply

    - Right angled dc connector;- Extra 5v usb dc port;- The smallest 100w power suply I found on dx;- Lightweight;- Several different connectors;- Auto adjust the dc voltage when changing the dc connector;- Displays the actual dc voltage;- Strong packaging box.
    The display and logo illumination is very noticeable on dark environment.
    This seems a good spare dc adapter, suitable to most laptops. Is also able to provide enough power to some high end units, and is compact for it's class - 100w.
  • Mobile power suppply

    posted by Koppen24

    Handy device, easily and accurately set. I use it in my car for media player. with 4 diodes I have the input voltage 2.5 volts lowered, then I could adjust the tension nicely at 12.5 volts. because a car when the engine is running 14.5 volts charging. The media player works well and without fault in sound or image
    the device is recommended for anyone with a laptop on the go with the car.
    Handy device for little money, certainly useful for a laptop because they are generally at a higher working voltage than 14.5 volts in a car.
  • Every experimenter should keep a few handy for when 12V is needed.

    Low Cost, small, light weight, efficient and provides a regulated well filtered 12VDC output regardless of the load up to 1A. A perfect replacement for older transformer type wall worts that provide an unregulated, often dangerously high, voltage when not used at the maximum rated load.
    Like most things, you get what you pay for. I haven't used this at the max. rated 1A load much and it likely wouldn't last as long as a much more expensive unit, but it's as good as any I've seen for 2 to 3 times the cost and should last as long as any if used reasonably (not overloaded or shorted for long periods, etc.)
    Perfect for whenever 12V is needed for a project, or whatever, and, at this price, something I can't afford to not always keep a few extra ones handy for when one is needed.
  • Neat little power pack for hobby projects

    posted by PA5UL

    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.
