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 ;~)
Review: Works as expected - I purchased this item to power a WIFI radio off a 12v car battery and solar panel. The radio is POE and 12v wasnt quite enough. Using this device I stepped up the voltage so the 300' network cable losses would be overcome. Worked exactly as expected. For those of you who do not understand electronics, this device is rated 5 amps at the lowest voltage. (5X5=25Watts) If you step the voltage up then the number of amps it can output will drop. Example: 15v is 1.66A.

## 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.

### ⭐⭐⭐⭐ problem solved!
*by P***B on February 3, 2024*

I'm getting 38V max from 12V in, but it was getting stupidly hot! A 20mA string of LEDS, consuming 760mW, required 210mA (2500mW} from the battery! Where did the remaining 1740mW go? Even with no load, it took 140mA (1680mW) from battery! Where did this go? Then I chopped out the LED indicator on the board. With same output, the input dropped to 80mA (960mW), and with no load it only took about 20mA (240mW). Wow! With my load the power reduction was 2500-960=1540mW. and at no load it 1680-240=1440mW. Almost the same saving of about 1.5W. This is much more than the LED indicator alone, and there is no longer heat build up ! Even if their LED is run from output voltage via dropping resistor, that is only 20mA x 38V =0.76W not 1.5W! This may be a bad design, certainly the efficiency is terrible (760/960= 80%) but at least now it runs cool! I hope this helps. So I recommend you break off the LED once it is working for you. Then it will run nice and cool! These have excellent regulation as long as you read the instructions - don't try running them from very low voltage, like under 5v !
