does this unit really discharge 28 million volts? really?

I don't know. But I accidently shocked my handad and it hurt! Don't know what it would feel like on an attackers hip, thigh etc. Someone asked a while back about the item and I didn't answer. I'll try to find the question again. Think it was about the arcs being on both sides...which mine isn't. Don't know if that is normal or malfunction.

With no way for me to test the unit i would say this much have one i bought at gun show that claimed to be tactical stun device with approx 11 million volts , i paid 49 bucks for it and its not as hot as this one , the volts are not as important as the sine wave put out and i am not trying either of these on anyone ! unless needed ! They where also selling this one at gun show for 80 bucks but didn't buy it there, i bought it here on Amazon and have given 4 away to those at risk of home invasion due to no guns ! P.S. i will be buying more of these for Christmas gifts !

I don't have a clue. As I understand it, there is no amperage with the charge, so it's not enough power to light up Atlanta, GA. Still, I wouldn't "play" with it. I know of no way to test it, except to "dry-fire" it and watch the sparks. I haven't even tried that. The flashlight works fine, the holster is very functional, so I assume the "stun gun" will work fine as well. Sorry, that's all I can tell you. If you "dry-fire " it, and you see sparks, I would assume it works just fine. 28 million volts...?? Who knows. It won't take that much power by far to discourage an attacker. Hal I don't have a clue.

I don't know... I can't get anyone to let me test it on them. Just the sound and how loud it is scares them.

I do not know, I have been using my unit for two or three years and it works very good and shows 12 volts.Joe

The output is a modified sine wave, though I don't know what it looks like. I picture it being a pixellated version of the real thing, with an unknown number of successive approximations to the sinusoid (like, step functions rising to .3, .5, .7, 1.0, then down again). I have used the unit to feed into the external power supply to my MS Surface pro, and it worked fine for the last two summers on a fire lookout. As I remember, sometimes it appeared not be charging the batteries in the Surface, but then, later, they would be charged. That might have been a spurious interpretation by the power monitor in the computer. Anyway, it was an excellent solution for back-country use.

Yes ours is a 20 volt max. It should say on your instructions your max voltage

ABSOLUTELY no!! That's ridiculous! Why would it need such large voltage?? Plain old 110 is what I have mine plugged into and it works great! I got it for my husband for Christmas and I think he has 1000 miles on it already!

I have not tried the unit above 35 volts However it has been working fine at 24 volts with a 3 amp load

Yes, I bought it originally because of my battery bank is also 24 Volt. This is ok. But I cant actually recommend this device. I bought it not only for inverter-function but also for charging and bypassing when generator comes into game. The last two, charging and bypassing, did never work out. I don't know if I got it already defect by bad luck or if it is just low quality.

I think the bugs get incinerated. Literally. It is unreal. Very powerful. Nothing left to examine. I think the lower voltage model we had previously preserved the bug.

I have no idea and I'm not going to try.In general the meter seems pretty robust at measuring large, variable loads in the direction it was designed to measure. My application was an electric bike with a typical voltage above 50vDC and loads all the way up to 1.5kw.

I bought one of these from someplace on Amazon. It does show volt level and it I believe it did show amps coming in from the panel.HOWever, I am sorry to report that this item quit all by itself in about a month. I called Amazon and they arranged for me to send it back and they refunded my credit card. I am now using a cheaper charge controller that at least works but no display other than lights.I really liked this item, but I need it to work properly and for a really long time.

I honestly don't know. I haven't had to do it. This thing has been great so far. It seems to have stabilized some of the surges I used to get. I had a Tripp Lite at one point and it was cutting out power by itself - basically doing the exact opposite of what I wanted it to do. I have no regrets so far with this purchase.

It will not work with 24 volts. I don't recommend this unit to anyone as mine stopped working after 6 months and I had to replace the unit! I am not a happy camper with Amazon!!!

Not sure, but it could be that your batteries are not holding a sufficient charge to register as full on the meter. Try checking each of your batteries separately with a multi meter. Each of my (old weak batteries) show 7v dc each when fully charged, and 6v when depleted. On the meter this shows up as overcharged (or near the H in the white CHG area) when charged and halfway down the green area when discharged. Hope this helps.

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

I am not familiar with that reading. My unit has worked like a charm. I would suggest that you go to the vendor's website. Maybe someone else has experienced something similar. Good luck!

Honestly I'm not sure, I have never checked the voltage... That would probably be a question for the manufacturer.

Yes - the output voltage is 12 VAC (not 12 VDC as a previous answer stated). But one of the other commenters was correct about the min load. When you just hook up the transformer and test the output without a load, it will read zero, or close to it. I thought the product was broken at first, but one I connected the load, all was well. It's been functioning great since (about 5 months ago).
