  • Nice for voltage regulation

    posted by waynedevereaux

    Great little device for regulating voltage. Especially when some electronics require 12 v constant and turn off below a given voltage. Small potentiometer to adjust the voltage.Boosts 7v up to 12v no problems. Great for monitors and cameras.Fast shipping was here in just over a week.
    A cheaper rate would be better
    Great device,id be lost without it!
  • powerbooster with CURRENT CONTROLL

    posted by lasermanathome

    This SKU delivers exactly that what other of these kind of voltageboosters do not have, currentcontroll!!So you don't have to use ballastresistors or other currentlimiting measures.Leds do have the habit to alter their resistance when they are in conducting state (like fluorescentbulbs but less dramatical)So this booster can drive powerleds without other components when cooling is OK!!
    Can be used to build massive ampifiers for carsAlso suitable for RC when higher voltages are used.When used 3 pieces parallel (with diodes) you can even feed an electric bike with one traction battery (12/24 VDC) USE an antiparraleldiode for the motor!!
    For inventors this is a very handy component with much (hidden) potential.
  • 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.
  • Variable voltageboost from 12v to 35v.

    posted by qwwwizx

    - Size, a very small package- Mount feets- Easy to equip - Very easy to use- Looks as good quality work- Very cheep
    I bought this to be able to variable boost voltage going to 12 non-pwm computer fans and to test if it can provide enough power to supply some smaller peltier elements. So far I have tested the voltage going smoothly from 12v to 35v, and a 3000 rpm scythe 120x38mm fan. My god a fan like that can eject some air when voltage goes up.
    Better than I expected. Looks a lot bigger on the picture on DX.com than it really is. I am very satisfied.
  • OK, but not for solar panel

    posted by Alexketto

    Excuse me, for my english.Good construction. No other parts needed. Fully adjustable output voltage within the specified value.
    If you would solve the use of solar panels, it would be a very nice gadget.
    Good, goog, but the Solar Power Supply?
