voltage boost module Customers Reviews

  • Flexible and useful boost converter

    posted by JimM0000

    Pre-designed and built boost converter that just works.WAY cheaper then you could build yourself.
    If you remove the adjustment pot, these can be used as current regulated supplies for LEDs by wiring in a current sense resistor.
    A great converter for way less than you could build yourself.
  • I was surprised that it works.

    A relatively large voltage range. Increasing the drive worked on the first try.
    When the need for constant output voltage for a wide variety of input values??, the product seemed ideal. Very simple to set up with great sensitivity. Easy wiring. With a bit of caution must operate on the first circuit.

  • Great product for testing

    posted by erlenmeyer

    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!
  • Excellent for driving high power LEDs SAFELY

    posted by walter6

    This is my best deal on DealExtreme. Product is correctly described. High quality components and production. It can be used for driving any high power LED (forward voltage 8-80V) from ><12V DC (description says 8-80V but this i have not tested) source and if tuned properly the working frequency will not go below 200kHz, emitted light will be consistent without any tremors in light intensity. I suggest that you tune it with warmed diodes because warmed are pulling more current than cold ones if you want to achieve 0,01A constant current precision. After intensive 48 hours continuous test i have complete confidence that this booster will protect my $200 worth high power (90-93 CRI) Bridgelux and Cree LED’s (constant current and constant voltage protection) against any input voltage variations. I purchased 2 of them and both are perfect (0,01A and 0,01V precision). Products are shipped 2-3 days after purchase ?.I will post some oscilloscope images for experts.
    Most countries are exempt from customs duties and taxes on shipments worth up to 20€, such as this useful thingy.
    After couple of negative reviews, this is my first positive one on DX. Deals as this one will make me come back for more.
  • 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.
