  • Great boost converter with stable power

    posted by bear123

    - stable voltage- effiecency is very good- able to boost variably and accurately - fuse- green power LED
    - I modded mine with sku 187376 (mini voltage meter V20D) on the output so I can see the voltage at all times under load. This is an easy mod and well worth the time spent. - I tested this boost convertor with 10 x 1.2v NIMH AA batteries running at 12v and I was able to get a maximum stable output of 26.2v at 76 watts or 2.9 amps. This is very good results for rechargeable NIMH AA battery power source. I will test next with some larger DC input power source and I will assume I will be able to boost to higher stable voltage but not exceeding the input output specs of this boost converter. Seems very efficient and provides smooth adjustable power. You can adjust the output as fine as 2 decimal places easily. What I mean is the adjustment provides fine tuning so I can dial in lets say 15.24v or 28.15v exactly as a random example. Once under load depending on the input power source the voltage will likely drop a little or a lot which is expected.
    Seems to be a great quality boost converter so far. Its small and did not create much heat with an output of 26.2v at 76w for about 5 min. I would think the 150w rating is fair for maximum spec for this unit. I would not advise exceeding this.
  • 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
  • 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
  • Great DC-DC step up module

    posted by marcosh72

    - Really works;- Fine regulated out, it's pretty accurate 5v;- You can recharge your phone or whatever from a single AA battery or any other supply, like a solar panel;- It's small;- Fits everywhere, seems great to embedded projects;
    I bought this to a embedded project prototype, works fine to power USB devices from AA batteries.
    If you want a cheap DC-DC 5v step up module with a USB out, buy this. Worth the price.
