What direction increases the voltage? Does it jump to max if you turn it past min?

I highly suggest you check the output voltage. This has no built-in display, and you should not assume it is the voltage you want when you take it out of the anti-static bag. As you adjust the output voltage, the meter reading will increase when turning the pot in the direction that increases the voltage. Make a note of the direction when you first adjust it. It doesn't jump back to max. It goes to max or min and stays there if you keep cranking on the screw.

Turn to the right to increase, left to decrease. It may take several turns to the left if its just out of the box to get the voltage say from 12v to 5v.

No, max is supposed to be 2.4 amp per port. Until someone can measure the output, it should be 2.4 amps. The one I got couldn't do 2.4 amps like the description said, I suspect it was less than 1 amp per port.

No, the idea for this one is a booster. The output is variable, but I don't think there's much overlap between its acceptable input voltage and its output. From my unit, it certainly couldn't go as low as a 5 v DC output.

There was a slide switch to set the voltage output. My unit went up in smoke as soon as plugged in. It also damaged the equipment it was plugged into. My recommendation is not to use, send it back for a refund before your other equipment is damaged. T H

It is a simple input/output arrangement. Power source is the input, supply to whatever device you want to vary the speed of is the output. This will only work in one direction, unless you swap the output polarity to run it in the opposite direction. Doesn't matter whether the + or - is the control path.

It seems to me that some of the batteries are "juicier" than others. If anyone knows a trick to bolster the voltage, please be sure to share with me. It's hawks that would benefit in my neighborhood.

It is adjustable. I have 10 of them and I have set them to different voltages.

I have no idea. But I do no that when energized its just a one way switch. When no power is sent to it it defaults to its de energized position.

In practice these things are pretty robust. As long as you do the adjustment while there's no output load (just your meter connected) and don't exceed the maximum rated input voltage, you're unlikely to fry it.EDIT: It sounds like one blew up on you, sorry to hear that. This is surprising to me, since the LM2587 has undervoltage lockout. I bench tested this for my application (dropping the input voltage until the thing turned off) successfully several times under 10W load.

No, there's no switch to set it to a higher voltage. Just comes with a basic AC adapter and only has an on/off switch.I have to apologize. I did not know this was possible - but I guess it's more common than I thought. The AC adapter says it will run on 100 - 240 volts AC 50/60 Hz and it's output is 4.5 volts DC. I haven't a clue how they do this with a simple little AC adapter but I see similiar labels on our cell phone chargers too.

I have not found anything. Just assume it's a 5V input, and output is inverted (High input = relay OFF)

I have a question can you change polarity coming to the device and how will it affect the power coming out my application is 12 volts into the device and ?? out also what kind of speed control can I expect

I used a momentary switch on the low voltage input side to trigger it on. There is a delay from when it kicks in, its not immediate. The length duty cycle, is adjustable and replacing the capacitor in the clock circuit can expand or reduce the window of time it remains on. But I don't recall the exact parameters as I've not used it in 3 months. Hope that helped you.

In the 110VAC position, it will float from about 96.5VAC to 116.5VAC without doing any correction. Over 116.5, it will Trim 10% off whatever voltage it is fed. Below 96.5, it will Boost 20% to whatever voltage it gets. It does this by changing the tap on the internal transformer. Good Luck!

Question doesn't make much sense. To get more current, you'd want to step the voltage up.

Pimple is right , this one also has a option to change the direction.One thing to note is to make sure you have a dual run capacitor , if not you need to buy another one , I know one or more reviews says you need an extra one but if you have a dual run cap already it's possible to wire it to it , you just have to terminate one of the wires.

Current is adjustable. Voltage is adjustable. Each has their own "screw". There are electrical limits to both of course. If you drive more than 3A make sure you cool it with a fan or similar. Works great for me. I have 20 of them in a lab setup.
