  • It's nice to have it!

    posted by CrypterMKD

    It's well built, nice soldering job, no short circuits. I tried to build it first, but this one is far better than the one I built. I use it to run 12V cooler in a cooling pad on the 5V ports on my laptop. I'll order a few more for my other projects. It even has one small red LED to indicate when there is power on input and if the voltage is too low the LED won't work. That makes it easier to operate!
    It's cheap and not worth building the simple circuit. I really like it :)
    It's the cheapest one you can find online.
  • Another good USB charger

    - Small, easy to use- Stays cool enough to put in an enclosure without worrying about overheating
    I bought these to build solar and battery powered mobile USB chargers. I haven't put them into a project yet, but they do work well on the bench.
    If you are looking for a basic USB charger with an On/OFF LED, this is a good, low cost option. If you need low idle current and a charge indication LED, SKU 146765 is a better option.
  • Great product for testing

    Good step-up module, with a clear display which display input and output voltage. Also you can turn it off (to save power). Welding is excelent and came with additional holes to fit it over a protoboard and M3 holes.
    I'm using this module to connect some bateries to make a regulable power source. I tested with a 550 mAh Li-Ion Battery and is working perfectly. Only have in mind the limitation of the board to 2.5 A.
    Great deal for DIY lovers!
  • 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.
