  • 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.
  • Needs more current than anticipated

    posted by Frijs

    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
    There is no description of the requirements, like input current / voltage. Perhaps I would not have bought this solution otherwise.I think this device can do a great job when provided with a steady power supply.
    Not a great solution for solar power conversion.A great solution to build an adjustable power supply.
  • Not very efficient, but versatile

    * Wide output range* Mount holes* Relatively small
    Find the desired resistance, desolder the potentiometer, add fixed resistance. This will increase stability & reliability.Also take care when screwing these to any conducting surface/material.And remember to add an mechanical switch.
    If you need more current then the small USB "charger"s can supply, or if 5V isn't enough for your use, then this or any other of the LM2577 adapters will definitely do the trick.But they have limits if the lithium cell is depleted, higher output voltages and/or currents may be problematic.This one is better for 2-cell applications.
  • Small and stable!

    Small form factor.Very stable output.Easy to see LEDs that show if it is in constant current or voltage mode.Very accurate potentiometer.Good use of heatsinks, does not get too hot.The PCB is very well labeled, so you know what everything means.
    Very nice product, very easy to implement in a project.I have used it in combination with a 24V, 3A power supply, and it works like a charm. It provides power for various projects, and is a lot cheaper than a complete lab supply.
    Good for people who know what to do with this.
  • Works for me

    posted by GabrielB11

    Cheaper than building it myself here... Since where I live the components are not common.
    Could be cheaper, maybe?
    It is compact and exactly what I needed to have my internet router working on batteries in case of power shutdown!It even has a LED that I find useful to know if it is actually working and I didn't know it had it.Got it encased and mounted in 10 minutes. The other one I made myself took me more than a week since I had to build my own cooper coils, and a generic circuit board because nobody sells them here.
