10 Pieces DC-DC boost converter 2A adjustable module voltage regulator board input voltage 2 Volt-24 Volt to 5 Volt-28 Volt output voltage
Specifications:
Maximum output current: 2A
Input voltage: 2Volt-24Volt
Maximum output voltage: 28Volt
Efficiency: 93% in maximum
(Minimum) (input-output) difference voltage when input is at (2 Volt and 50% of max-input-Volt), loading at (50% and full rated current).
Product size: 36 x 17 x 14 mm/ 1.42 x 0.67 x 0.55 inch (L x W x H)
Method of use:
The adjustment of potentiometer can adjust output voltage, output voltage is greater than the input voltage.
Package includes:
10 x DC-DC power apply module
Attention:
The input voltage should not exceed the maximum input voltage.
The peak current output current no more than 2A.
Tips:
Reverse the potentiometer 20 times before taking the goods to test.
Some customers report that the output voltage of the module cannot be adjusted and is always equal to the input voltage. When you encounter this kind of problem, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally.

Works good for me. Following the instructions, you turn counterclockwise ~15 times which sets output voltage to around 28v. Then clockwise to reduce voltage to your desired value. I needed this to turn 4.22v into 12v, and the voltage output was stable within 0.05v while adjusting input between 2-5v. Once input drops below 2v, output drops to slightly lower than input. All 10 converters come individually packaged.

The tiny + & - are easily obscured by hot snotting the corners so be sure to write bigger markings. There's no reverse current protection, but the spare parts are worth more than the original board. The pot is pretty crusty compared to a normal multi turn pot but better than the single turn pot on hiletgo buck converters.

These are remarkable voltage boosters. Connect them to an 18650 cell with 3.8V in and you can get almost 28V out. I think they are rated for over 1A out, and I believe it. They also have short protection. Voltage is adjusted with a screwdriver put to the precision pot that looks like a blue block. Slightly non-linear and needs many turns to go through the whole voltage range. A bit tedious, but one can also unsolder the pot and replace it with a more direct one (100kOhm). I built a 2-voltage mobile adjustable power supply with one of these, plus a buck converter, giving me a range of 1.2 to 28V. Very convenient to have.

I purchased a pack of these only 2 of them work the others only read the same supply as is going in. tried turning 10 times clockwise multiple times but no joy

Just make sure before applying power to turn the potentiometer about 20 times CCW And before applying any load adjust to desired output with a voltage meter.

These MT3608 modules work great but since they don't come with instructions, there are a few things you need to be aware of. I'll explain:One of the product photos includes the text "Reverse the potentiometer 20 times before taking the goods to test!" which really should read "Warning: Before applying power for the first time, turn the output voltage adjustment screw 20 full turns counter clockwise (CCW)." If you don't do this there's a good chance the module will be damaged when power is applied.After turning the trimpot 20 turns CCW, connect the input voltage you're using to Vin. This voltage should be 2V - 24V. Do NOT connect anything to Vout except a voltmeter. With the Vin voltage applied, the output voltage will probably be higher than you want so adjust the trimpot in a CW direction to lower it. The output voltage must always be 3V or more above the input voltage so watch your voltmeter closely while adjusting Vout. With Vout adjusted to your voltage, you can now use the module.Note the trimpot does not have mechanical stops like a conventional potentiometer. When you get to either end, the screw still turns but it has no affect on Vout. If this happens just turn the screw several turns in the opposite direction while measuring the output voltage.

Wanted to use this product for a DIY LED bench supply tester. I pulled the first one out, ran the trimpot CCW and gave it power - worked fine, voltage adjusted with trimpot as it should. Pulled power and desoldered the trimpot to add a potentiometer so that I could put the whole thing in a case to make it easier to use. after adding that the unit would not output any voltage and tripped my power supply. No worries, I probably messed it up - that's why I ordered a 10 pack. Second unit, same thing except this time I got some smoke. I pulled 2 more - same setup - trimpot CCW 20 turns and apply voltage - I put 12.5v on one and 5.3v on the other and both showed over the input voltage (as expected) 28v on the 12v and I dont remember what on the 5v. This was hooked only to my fluke no load present - within 30 seconds the 12v line converter had tripped my power supply again and within 60 seconds the converter on the 5v line stopped outputting voltage. Literally didnt even have time to adjust the trimpot to see how well that was working. I am not planning to secure any of these inside of any case given how reliable these have been. I am no professional but have been soldering on LED strips, individual LEDs (3/5mm and addressable) RC and FPV drones for a few years now without issues. And as much as I wanted to give the benefit of the doubt to these when the ones directly out of the package can't survive I cannot recommend them. Maybe I got a dud pack - the rest of the reviews were enough to give me confidence - but beware and test a few before you do any projects so you dont get stuck with half the order that you can't return.

Works perfectly. Used one to power a led strip with a 5v 1a brick.

Isn't it amazing that boost converters have come down to this price and in a postage stamp size? I have used these to convert 12V DC to 15 and also 24V. Both applications have a current draw of It goes without saying that the DC coming off is noisy due to the switching going on to boost the voltage. There is no significant filtering on this board but you could add some on the output if your application is bothered by the spikes that come from switch mode stuff.

im running a usb 5v in -12v out on this step up to an led strip , this has a distingtive ringing at a very high pitch and will need a box to shield that sound some, , unit is mounted 3 ft above my head and isnt loud its just thereunit is just fine in operation. bit of arse to screw counter clockwise 20 times first and i haven't had any luck getting a step up with some other modules in the pack , user error i hope

I got them for a different project, but so far I have used one to power my little netgear gigabit switch from a USB port. 5V -> 12.2V.Adjustment was easy, and so far the output is very consistent.I've been running some traffic through the switch, and so far the converter isn't even hot to the touch.FYI the ones that I received had holes drilled through the pads, unlike what the photo shows.

These are really useful devices to increase a supply voltage. I have used one as a general purpose supply (e.g. for checking zeners) and others for generating 9V from USB or LiPo batteries.It would be easy enough to home built something to do the same function but probably more expensive.
