5pcs Songhe 150W DC-DC Step Up Boost Converter Voltage Adjustable Module Laptop Voltage Charger Board Car Power Board 10-32V to 12-35V 6A Review

Tested to work as power supply for my Li-ion battery charger in different voltages for different battery sizes. So far, so good.

Description has been updated since purchase but for TWO units not 20 not sure what is wrong with the seller repeating this 5 times for the description.

Very good circuit as advertised. Wire connections are a bit tight and require careful adjustment to avoid short circuits, but otherwise very easy setup and fairly easy adjustment.

We used one of these to increase the 12v power supply on the boat to the 19v required for an LCD TV. Works perfectly! Even though the voltage on the boat has dropped well below 12 volts, this continues to provide the TV with what it needs. I've been using it for a few months now. Very happy.

Works exactly as described, this time used a 40 volt Ryobi battery charger which stopped charging due to a voltage drop below 30, set this little booster to 35 volts and was able to get it to charge before that as soon as possible. I put the battery back into the charger and it charged the rest of the way.

I mean can't really complain as they work well and still have great value but either the list is totally misleading e.g. B. "20 components on the boards themselves", or that's a typo. I will be lenient when I say that this is a misunderstanding on my part and not a distortion of the facts on your part. The component is super customizable so you don't need to have more than a pair - I just thought 20 was too cheap not to have lol.

Use one of these booster modules to power your anti-slime electric fence. shutdown 12v. I boost the motorcycle battery to 20 volts to push my charge through the 24 foot high resistance copper band surrounding the raised bed. The module is relatively stable and only fluctuates by a hundredth of a volt with each start. I have melted this circuit twice, once at 5 amps and the second time just before the module at 7.5 amps. So far so good, the first time it works without any problems.
