Sold in a convenient 20-pack, it offers great value for bulk use and experimentation.

## Description

Feature: Input voltage: 2 V to 24 V Output Voltage: DC 5V-28V Maximum output current: 2A Efficiency: 93% (Minimum) (input-output) difference voltage when input is at (2 V and 50% of max-input-V), loading at (50% and 100% 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: 20 X MT3608 DC voltage regulator board

Review: The boards are defective. Not really finally. - 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.
Review: Failed within hours - Two of these failed immediately. Other two worked for a while. I am using 2 of them simultaneously for two circuits up-converting from 12V to 24V, powering a 16W circuit. But both of them failed within a few hours of use. The failure resulted in them producing only the input voltage at the output. I am on the last one (of the 5-pack) and I expect it to fail as well. Very unpleasantly surprised. Actually heavily disappointed. I removed 1 star for each failed board from the 5-pack. The ad says that these up-converters work with loads up to 2 amps. I am using them only for 0.7A each so they should be able to handle that just fine. But they do not. I requested a replacement package, foolishly hoping that another batch might work better. I will post an update once I test them out. Though I should not fail to provide more details about the up-converters. They come with nice pre-drilled solder pads, they are big enough for bigger wires for 2 amps, that is a nice touch. The adjustment trim-pot is pretty funky, the quality really is not good because when it is turned maybe 1/4 turn, the voltage barely changes, then it is just barely touched and now the output voltage jumps an extra volt. The trim-pot operation simply is not smooth enough for fine adjustments. Otherwise, once the trim-pot is adjusted, the board holds the output voltage well, no big deviations, maybe a tenth of a volt but that's also the reading error on my DMM so it's hard to tell. Size of the boards is acceptable and as advertised. If I ever get any that will actually stay working, I will slide them into a 1.5" heat shrink sleeve for protection. As far as the refund goes, I have been waiting almost a month. I have neither the boards, nor my money. On the product returns page, desertcart indicates when I should receive the refund. Whenever the date comes up, they move it out. The return page shows "Refund issuance is delayed". No explanation. desertcart is pretty good about issuing a refund once they receive the merchandise but they've had the boards 2 weeks and no refund. I wonder about their actual procedural policy and why the process is stuck. Disappointed on this front as well.

## Features

- The dc-dc dtep up boost power converter maximum output current: 2A; Board Size: 36 X 17 X 14mm/1.42 X 0.67 X 0.55inch(L*W*H).
- Mini DC-DC step up voltage regulator with DC 2-24V input and 5V-28V output,just connected with USB power adapter then you can get 9V 12V 18V 24V voltge.
- Widely used for storage battery, power transformers, DIY adjustable regulated power supply, industrial equipment, 5V, 9V, 12V, 28V output, etc.
- MT3608 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload.
- Note: Before the first use, the module is not powered and not connected to the load, the blue potentiometer copper head a word mouth adjustment cap, aligned with the direction of the chest, counterclockwise rotation of the potentiometer to the end of the "ta" sound, and then clockwise rotation of the potentiometer more than 30 turns, and finally connected to the power supply, using a multimeter to monitor the module's output voltage to achieve the desired voltage

### ⭐⭐⭐⭐⭐ Trial and try till it works
*by A***S on September 15, 2025*

Hello I purchased the MT3806 so I could boost my 9v to 11volts DC. My intended use was for raising the voltage of an original Made In Japan CE-2 guitar pedal. My first thought was that the MT3806 was small enough that it could easily be hidden, and I could use heat shrink on it to hide it. My first attempt to use the MT3806 was a failure, it literally sparked, burnt and caught on fire when I turned on the power. On guitar pedals the Center is Center Negative so I reversed the VIN- and VIN+. After that it started working but the voltage did not change at all. I returned to Amazon and read the reviews and started with another brand NEW MT3806. The great part is they are very affordable(cheap) and it doesn’t hurt my wallet to try again. I tightened until the thread ran out and clicked(no voltage change). After that I began to lefty loosen the Screw type potentiometer. It took a long time but it worked towards the end of the screws thread. I was able to regulate the output voltage to 10.76vDC from an input of 9vDC. Of course I do think and I also know that I don’t intend to use a load greater than 30mA. Worked out great, no issues, no noise issues either in an audio device.
