Your cart is empty. Feature:
Input voltage: 2 V to 24 V
Output Voltage: DC 5V-28V
Maximum output current: 2A (regular 1.2A or less, 1A or more to strengthen the heat dissipation)
Efficiency: 93%
(Minimum) (input-output) difference voltage when input is at (2 V and 50% of max-input-V), loading at (50% and 100 percent rated current)
Method of use:
The module of the IN+ and - after 2~24v, adjusting the potentiometer can adjust output voltage, output voltage is greater than the input voltage
Matters needing attention:
The input voltage should not exceed the maximum input voltage
The peak current output current no more than TV university
When the module output voltage can not be adjusted, the output voltage is always equal to the input voltage.Please adjust the potentiometer counterclockwise 20 laps or more (Let potentiometer against your chest, counterclockwise turn boost)
Package Included:
10 X MT3608 DC Voltage Regulator Board

There's a little work involved before you can use these, I wanted to boost 5 volts to 12 volts.Turn the module over and solder these two connections together otherwise the module will not work

I have some lights that use a USB style power supply to power 12 VAC LED lights. The 5V power was fine with older less efficient LEDs (resistively current limited) but when I installed newer LEDs they did not work. This very inexpensive boost converter allowed me to continue using my existing lighting with new LEDs by simply placing the boost convertor inline and adjusting it for a matching quality of LED output. For me this was a good solution that worked well and was very cost effective.

Works great I used one of these to wire a light on my rc car. I bought a traxxas light bar and it will not run off 6v so I used this booster to take my 6v power in to up power to the light bar. these boosters are small which allowed me to wrap in foam and heat shrink to keep it safe in my rc car. so far I have ran 4 batteries through my truck bashing around and booster is holding up great to offroad rc driving conditions.

I had it on the bench, and it did nothing...== In the description: =="output voltage can not be adjusted, the output voltage is always equal to the input voltage.Please adjust the potentiometer counterclockwise 20 laps or more"I did more than 20 turns, then it went to 25V with 3.3V in. It's touchy on the lower side, but it works.

I received 10 boards and tested 1 of them and did not work with 4.1v input. No change in output voltage regardless of potentiometer. Tried two more boards and they are the same. The boards should work with greater than 2v but did not work. I am returning them no point of checking remaining 7 boards.After further testing none of the boards are defective. The issue is that you need to turn potentiometer at least 20~30 turns all the way both sides and at one point output voltage will increase. Turn until u hear click sound. If no change then turn opposite direction and it should work but many turns in that direction.

It didn't work out of box. VOUT reads a bit lower than VIN, suggesting the chip not switching. I tried to adjust the pot and no luck.After reading so many 1 star reviews with the same behavior I was a little worried.Then I checked the datasheet of the IC (MT3608), measured the layout of the board out, eventually figured it out.Is it a 100k pot and when out of the box it was adjusted so that VOUT is almost shorted to FB, in which case the IC won't be able to regulate FB to 0.6V, which is its desired setpoint.One might want to crank the pot all the way counterclockwise (oh boy it was a lot of turns) so that resistance between VOUT and FB is closer to 100k instead of 0 and then go from there.I then connected VOUT net to my electronic load for up to 5.2V@2A load and it handles that just fine.It does get uncomfortably hot when wattage is above 15w or so, you will want to validate for your application. Also the regulation linearity is just so so underload. But hey I paid 8 bucks for 10pcs so wouldn't complain too much.TLDR: Measure resistance between pot pin 2 (the pin in the middle) and VOUT. If too low (less than a couple kOhm or so), it's not likely to work as intended. Turn the pot counterclockwise until this resistance reads in 10kOhm or higher, then connect your VIN and adjust from there.

The goal for these boards was to step up the voltage from 12V (11.6V measured with Fluke multimeter) to 24V with a maximum current of 0.1A for a small 5015 fan. These boards were never hooked up to a fan. Upon bench testing and adjusting, the first board had a reversed polarity output. The VOUT- showed +24V and the VOUT+ showed -24V. I triple and quadrupled checked that I didn't have any of my leads reversed and they all looked fine. I powered off my power supply and when I turned it back on, the product now showed 11.6V output and would not step up power at all. I chalked it up to a brain fart and tried a second board. The second board never stepped up power at all no matter how many adjustments I made on the potentiometer (believe me, I went end to end and was aware of the 20 turns necessary for adjustment). Then all of a sudden, the board caught fire and blew a component. They were only connected to a multimeter. I didn't bother testing any more converters after that. Avoid this product.

Update: Lowered my rating to 3 star. I originally ordered a dozen in January 2023 and they worked great (original review 5 star). I ordered another dozen in Sept 2024 and the first 3 I tried didn't work. Order at your own risk, seeing other more recent reviews it appears there are some serious quality issues going on. There appears to be a few differences on the PCBs between my two orders (a new silkscreen on the back clues me in that they created new gerber files). Upon very very close inspection I notice a couple vias that are different, but there's only 6 components and this is a very simple circuit - there should have been no reason to change it. Also - from my original order there was one (pictured) where the inductor was broken when I took it out of the bag.So, ultimately, they are cheap - if you order them, order far more than you need and test them with a meter before trying to use them.Original review:Easy to and quick to use, might as well have a bunch of them handy for various projects. Extremely useful when trying to work with USB power, you can take the 5vdc from the USB and step it up to what you need to run another board if you need 9 or 12v instead. I wired it up to a usb port, tossed a voltmeter on the outputs and turned the pot. until I got the voltage I wanted. Be aware of the power limitations of your usb port of course.

I had the desire to reliably control my Noctua 12V 0.6Amp fan, but when powered from the wall-mounted, socket with a USB port (5V, 3.1Amp max supply). The fan works brilliantly within the full voltage range between 5.2V-12V. I am very happy with the purchase as the unit does not heat up at all and is stone-cold even after 3h of continuous work. The pot is quite sensitive, circa 2 turns per VoltLittle side note: Comments sections are really entertaining: it appears that only a few people had sufficient grasp of knowledge, that from 4.2V LiPo battery, even if you connect four of those boost units, you will not get reliable 110V AC ;)On the other hand - always choose the boost applicable to the project. Happy tinkering, guys.

I use these module in a product I sell. I need a source of 20V from the internal 12V supply.They are simple, convenient, readily available and inexpensive.So far, they have been reliable and easy to use.
