How do I adjust this voltage reducer

[Adrianlle]

Lost the Instructions. Can’t work out how to reduce the output voltage to 5v. Ther is an input and output knob that pushes in and turns. But neither make any difference. Same as Others on here - Lenny? - have I think. Any help appreciated before I bin it! Thanks

The two blue multiturn pots one does voltage the other one is current limit.
The buttons just change what the display is reading, input volts/output volts/current.

This is mine.

Bear in mind whatever you set the voltage to it will be the same voltage out of the USB port.

The things need about 30 turns from min to max, not like a normal pot

those are handy little voltage reducers. but bear in mind they are not regulated in the true sense of the word and as the load changes, the output voltage will also change, so best to make the final tweak to the voltage when the 'normal' load is active.

Never had that problem with them but I always turn the current limit up to max.

Fantastic. Just got around to hardwiring the Huwaei routervia this reducer. As you say, the pot needed a lot of revolutions! Now all done. So , as always, thank you all.
