does this have both positive and negativively charged ions?

Yes, when the salt dissolves in water, there are both positive and negative ions.Best wishes, lh

The one with Red O-Ring is the positive. There're also positive and negative mark on them.

You either connect POSITIVE to the POSITIVE and the NEGATIVE to the NEGATIVE. Or you can BRIDGE them together the TWO POSITIVES together and the TWO NEGATIVES together. Both will work either way.

It looks the same. I have had 2 pumps so far and both have the positive and negative reversed. Be careful you might have to re adjust the positive and negative so it pumps correct.

It depends on how large your room is. Small room just one, really large room two. All four and the room can start to smell of two many negative ions. It also depends on how long you leave the lights on.

The side that has the plus symbol is positive side. Just like in the picture above

It does not state. However, I can tell you that it is Lithium ion and I have used it intermittently over the last two months and it has not been charged. It uses little and charges quickly. I have not tried to use it to the point of total depletion, so cant really tell you how long it will run. I just lasts quite a long time.

No, this produces no negative voltage. The "-" terminal is marked to indicate what you would normally refer to as DC ground

No, no polarity detector. You have to change the connection to measure charge or discharge currents.

There are some electrolytic capacitors. They are polarized. The rest of the assortment are ceramic or Mylar, or whatever and they are not polarized.

just make sure you have the plus side of the battery incerted correctly there is a plus side and neg. side they are marked plus or minus the minus is - the plus is +

Barely works. Doubt it could be ionizing. I used to have a negative ion generator and it is a different kind of unit.

Make sure the polarity is correct. The negative pin -- Is marked on backside.

Supposedly the "negative ions" produced by the Truman Cell (I think?) actually reduce Ozone, according to some of the company info I read today. It even says that since the negative ions cause dust to be "heavier", not to arrange the air purifier in such a way that it draws the room air over you while sleeping. Presumably the heavier particles it's trying to capture, will land on you and you'll be breathing in the dust and pollen, etc before the Truman Cell can get them. Sounds good to me. And the air does have a weirdly fresh odor, to me. My DH, on the other hand, "don't smell anything!". (which is the whole point.)

mine has yellow and black, the yellow is positive and the black is negative, I will guess the brown is negative and the yellow is positive, a continuity tester will tell for sure

On the white plastic carrier that holds the batteries, on the side on it, there is a faint outline of an arrow. This arrow needs to point inward as u put it back in the light. As far as positive and negative, any device u put batteries in....u put the flat part of the battery on the spring

Not sure why there are two sets. I wites them together and it works. Positive to positive and negatives together.
