Are the voltage settings accurate. If you set it on 9v, Do you get 9v? I've had other brands that the actual voltage output wasn't even close to the s

It is the crappiest product EVER! the connections are bad and cause the sound to have loud crackles. It stays on the voltage you want...but the points that go into the boxes move alot and are not tight. We have actually had to shore up something next to the connection so it would not make loud pops. Forget any dancing or bouncing on stage. The connection will disconnect and we have to push it back in during a performance. I went to corded mics and i dont have any problems now at all. this product is not like the original shure powerlines that came with the mics when I bought them. good luck.

You get about 9.5 V not under load. (i.e. when the unit is measured into a high impedance voltmeter).

Depends on what you call accurate. Output voltage MUST be a little higher than battery voltage since it takes more voltage to charge, and working rage area for voltage to run electronics, because of resistance and knowing that battery voltage will fall as the battery drains. My charger/converter runs about .3 or .4 volts higher than the specified settings, which is about normal. Note, most electronics can take at least a 20% higher than rated voltage connection. This does increase performance in many devices, depending, but there will be more heat buildup the higher the over-voltage.

I found the voltage approximate with 0.25 to 0.5V. Generally the measured voltage would depend on the load. A high current load will likely drop the measured voltage.

I use it for a picture frame, it's constantly on 24-7 and I never have a problem with voltage, appears to function normally. I have never measured the voltage to check output though.

You have to have your "load" connected first, otherwise the amps will remain at zero. By load I mean whatever it is you're trying to power. First connect your load, then turn the voltage all the way up, turn the amps all the way down, and turn on the power switch. Then slowly turn up the amps, then slowly turn down the volts to desired volt settings. Again, you have to have connected whatever it is you're trying to power to power first. I know, it doesn't make sense, but that's how it works. It threw me for a loop when I first got mine too.

It has 12v, 9v, 7.5v, 6v, 4.5v, 3v settings.The gadget I have requires a 7v but for some reason it didn't work on that setting. So it ended up working on the 12v setting! Go figure! Hope I haven't made your decision more difficult. Amazon is great though, they're so good about returns :)

Hi, sorry for the inconveniences. First please kindly confirm the working voltage is steady, secondly, the driver may not work properly. If you have any problem with your order, please kindly contact our customer service for replacement.

have you measured the output voltage with a voltmeter? I have the 9v pump, and the 9v AC wall pack I measured outputs 12v (actually closer to 13vdc). If you actually try to run the pump on 9v it doesn't work as well. I am not sure what the acceptable voltage ranges are but you can run the pump safely on 12v. I actually have a power bank with 12v output that it runs for days on (http://smile.amazon.com/gp/product/B00VF6B8X6 its expensive, but you can get similar units on sale for pretty cheap and its a lot smaller and more useful than this silly pack).

Mine showed up dead right out of the box. Plugged it in and turned it on with nothing connected but a voltmeter. The light lit up on the switch, but it had no output. I didn't want to open it up and tamper with it , so I just returned it and bought a better power supply. Read more reviews and you will see that others have complained about this supply burning out in short order at moderate loads.

My power supply got thrown into a box of other power supplies. Now I don't know which one it is. I just need to know the voltage/amp rating for mine. I found new ones here: http://www.fitnessrepairparts.com/cart/ViewItem/13002288 If anyone knows what voltage these put out, it would be very helpful to me.

I use a generic one, with interchangeable connection pins and variable voltage (but fixed 3A). Set it to 9V, center pin positive connection, and you're ready to go. I'm pretty sure you can find one here.

The owners manual is written in 7 languages and doesn't say anywhere what the voltage is. The unit itself doesn't either. So I then checked the end of the plug and it says it uses 9V @ 200mAh. Translated = very little.

Mine has been rock solid at 110v. My source voltage varies between 121v and 128v so correction is always on. Sounds like you may suffer from a low voltage source, which if you're set at 110v the device would not compensate for since that variation is below it's threshold. Have you tried setting to 120v and seen if it brings that voltage up to a stable value? too much load could also be an issue....

I have been asked this before. There is no information on the package regarding voltage.

I run mine off a 3S lipo (12v). It may have a voltage ranges it runs off of. I just don't have the manual in front of me right now.

The operating voltage is set up for 7.0 , 12, or 16 volts . if the voltage exceeds 16 volts .In my application I am using a 3 cell, 11. 1 volt. it works well at this voltage

Prior to answering, I carefully reread the instructions. No where is this question answered or addressed. I simply don't know. Technical info from instructions:" Power requirements: DC Adapter: 9vcd, 500 mA. Sorry!

I have no idea but measure whatever setting you chose - with good voltmeter and preferably under load. This power supply puts out twice the voltage the setting indicates. Please use with caution.John

could you please check and tell me what's the rating for the external DC supply ? Vdc ? and current rating (mA)?appreciate your help.thx

I always used the 4.2v with no problems . I tryed the 3.0 and it was a little dimmer when fully charged ,almost couldnt notice tho
