  • Step Up Boost Module

    Very nice product you can adjust the output easily.If you want this for solar panel its a great Step upExample i got a 5v solar panel and i put in output 12v and i can turn a fan at the max speed ect.I recommend this product.
    easy to make contact just put a thread inside the In+ and In- and same for Out and work.
    Love this product.LM2577 DC 3.5~18V to DC 4.0~24V Voltage Step Up Boost Module - Red - Model: LM2577- Color: Red- Material: PCB + Plastic + Copper- Input voltage: 3.5~18V- Output voltage: 4.0~24V- Input current: 3A (max)- Input continuous working current: 2A- Great for electronic products or DIY
  • Worked well for some things

    -Fairly solid build quality-Red LED confirms circuit is working-All solders look good to me-Works with many different batteries-Delivered a good 4.9-5v-Very small-Solid USB connector
    Mine came in it's bag with a little black chunk missing off of the coil towards the back, however it still worked fine
    This is a good product for older devices or devices that require less current, but the max on this device is 1A (probably less in reality), and it cannot charge many new devices which require high current to charge.
  • Great object

    Regulate your current to the standard USB voltage and intensity.It also has a small led telling you when electricity is passing; if you use it with a solar panel (like I've done), the led will tell you if the panel is catching enough light.
    I think this object can have a lot of applications. The standard USB port is great.
    I recommend you to use this with a solar panel
  • 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.
