Review: Works perfectly boosting 12v to 24v regulated output - I tested these on the bench. They work as advertised. 5v input to 35v output. I am using for 12v to 24v. I was happy to see the output was regulated, so even if I lowered or raised the input, the output didn't fluctuate. They are rated for 5A. I haven't used under load yet. Will report back if I have any problems. The build quality is excellent. Screw downs are larger than most and strong. Input is one side. Output is the other. The potentiometer adjustment is solid. I've seen really weak ones, but these are tight and move the voltage predictable. These are an excellent buy. I will spray with acrylic/conformal coating to protect the circuit.
Review: A good step up regulator for 18650 cells. - I've built a home made stack of 18650 cells, every cell individually fused, for hurricane preparedness and needed to step up 3.6 to 4.1 volts up to 5 volts for all the cell phones and other rechargeables in the house. This step up converter has so far tested well for the purpose. (even runs usb fans and lights well) One caveat... Make sure the resistance between source voltage and the converter is very low ohm, and you may want to add an extra electrolytic and mylar capacitor across Vin to keep the converter nice and stable. To thin a wire on input can allow this regulator/converter to get unstable which leads to excess heat/inefficiency. Had this happen. Fixed by jumping to 14~16 gauge and adding aforementioned caps. I'd suggest a home made crowbar circuit to keep any over voltage from accidentally damaging any usb circuits as well. AND DON'T FORGET TO FUSE 9-] In this old techs humble opinion ;~)

## Questions & Answers

**Q: Using 6 of these 5v to 6v for 1.7a mg995 servos. set outs  6. no movement. measured. damn things showed 17 to about 30 and destroyed my servos! why???**
A: These boost converters are not current limited, most likely your servos don't draw a consistent amount of current. When electric motors turn on they draw a  huge amount of current(compared to normal operation) sometimes over 8 times as much, called inrush current, this would cause the boost converter to send in a large amount of voltage to compensate. First, never trust the output of the boost converter, always decrease the voltage to minimum and then slowly work your way up untill your motor starts spinning at 6 volts. That will most likely solve your problem. And second, because servos are current sensitive devices it is always better to use a current limiting boost converter with them IF you are putting them under a heavy load. Don't worry, pretty much ever diy'er has burned out electronics before.

**Q: Can this be used with the 5v dc output from a usb power source to a 20v dc bit of equipment (low power)?**
A: Yes, your setup will work. You will have to adjust the output voltage using the blue component with the golden screw on top. Best to measure the output voltage with a multimeter before you connect your equipment.

**Q: Can this be used safely with an arduino and if so should it be used with the 5V out pin or one of the Analog out?**
A: Do not use any arduino pins to power this board. You will fry your arduino. Power the boost converter directly from a dedicated power source and controll the output with a relay.

**Q: Can i use this to step 12v from a battery to charge a laptop with these specs - output: 15v dc, 3a, 45w?**
A: Not if you are using the laptop while charging, this converter is rated only at 30 Watts so find a more powerful converter. I would go with a 100W one with a nice heat sink just for peace of mind.

### ⭐⭐⭐⭐ 45V is overly optimistic, and it does get hot.
*by J***. on November 12, 2021*

At full load, the modules I received achieve 38V and get very hot. Unfortunately with such a small footprint board, the positive terminals, including the exposed positive pads on the underside, are right next to the ground connected screw terminals leading to very easy short circuit conditions. I found this out when I placed the board on a heat sink and the output wires (to a battery pack) shorted, catching fire lol. That was the battery's fault and that I didn't fuse this connection though so don't blame them for that part. Just remember that these contacts are really close. The module was fine. I like that the components are all nice and beefy, the board is covered in thermal vias to use its ground place as a radiator, and the screw terminals seem very solid. This technique also spreads heat to other components on the board however ;) All traces on the board seem to have more than enough copper for its normal operating range, and the solder joints are very well done. The cleaning and finishing was nicely done as well. The most experienced engineer I work with took a look and also remarked about the build quality. Would be 5 stars if the easy short circuit condition could be resolved. I think the description should mention that additional cooling may be required for operation at full load and 45V is way off from the adjustment range available on the boards I've tested. I will be using these though, and probably will be ordering more. I would use a fuse on the output for safety if you intend to use it with something with also provides current, like in my case with a large battery bank.
