Questions about coils and rebuilding

[EphoraL]

I have a Protank Mini 2 and I have a few questions to get me going.

are the original in the box coils rebuildable? They look different from all the videos I watch.

Second, what ohm coils are recommended? I need to buy some anyway, the ones I have are 2.5 ohm. I have an eGo-T battery if that helps.

Lastly, What gauge kanthal wire is recommended? I have no idea what to buy for kanthal, and should I buy silica or the cotton setup?

oh and do I really need an ohm meter?

Thanks, just trying to learn

Kanger coils are rebuildable, but not very easy.

With an eGo battery, you will get a better throat-hit with a lower ohm coil. The higher the ohms, the less heat you will get at the coil for vapor. An eGo will only put out about 3.3 volts and is pretty consistant.
Most advanced vapers will go variable volt or variable watt so that they can pick how hot their coil gets with any ohm coil.

If you are set on trying to rebuild kanger coils, smaller guage (higher number) will fit better, but you need a certain amount to reach the ohms required. A thicker wire will have less resistance (ohms) but may not fit inside the housing. I think 30 or 32 should be adequate.

YES YOU NEED AN OHM METER! If you sub-ohm an eGo battery, nothing good will come of it!

Ditto for everything everman7 said

~2 to 2.5 ohm coils

(ProTank/Evod coils are pretty much the same)

Read read read about safety first, watch every video you can, and plus 1000 on the ohm meter. You don't just need one, it's required before rebuilding...REQUIRED!!

And go watch EVERY video made by PBusardo!!!
Start at the beginning with a crapton of juice and a few gallons of water and maybe some food.
See you in a few weeks!

Okay, can someone give me some links or shoot me brands to buy this meter?

Ohm Meter and Battery Voltage Tester

great vendor as well!

Look for "digital Multimeter". Harbor Freight has some for about $6, e-bay has a boatload.

Rebuildable Atomizer Systems is a good place to learn and ask safety questions, but for the protank stuff ask around in Clearomizers because kanger coils can be rebuilt but are not considered a rebuildable. I like the suggestion of 30 or 32 gauge kanthal. I get mine on amazon. Organic or sterile cotton can be purchased from your local pharmacy, and its usually $4-5 for enough to last a few months.

Here's a good video Nano Micro Coil build for Kanger Protank 2 - YouTube

Basically do what he's doing, but use 30 gauge and wrap it around a 1/16" drill bit instead, and do 10-12 wraps.

I use 28 gauge but I run it on a variable device, and I know with 28g, 10 wraps on the 1/16" drill bit is consistently 1.25 give or take a few hundredths. I would not recommend going any lower ohm than 1.5 with the eGo, so stick to the 30 gauge or smaller and you should be ok.

This is the ohm meter but don't buy it from here because it's a little to expensive. Always use your googlefu, young grasshopper.

My advice is to not rebuild pro tank coils. Maybe I just never tried hard enough but I could seriously never get them right! If you want to rebuild I would recommend getting some sort of RDA because they are much easier and more fun. DEFINITELY GET AN OHM METER. and a legit one too. My Zmax has an "ohm meter" that is always off by about .3 ohms.

Plus the coils always got that rubber taste I couldn't figure out how to get the wiring right in the rubber stopper

But Those are just my thoughts

Hope it works out for you!

I was actually told to try rebuilding Kanger heads before RBA, RDA, etc. The reason as explained to me was... If I can build a consistent coil on that setup, it would make it easier when and if I step up to more advanced builds. Now, with that being said, I can't stress enough how much others have said about the safety concerns. It should never be done without an ohm meter, or a multimeter. You MUST know what the resistance is for 1) to ensure it is infact a safe build to use, and 2) to track your consistency of builds. What I mean by consistency is if you are targeting say 1.8, but you get a reading of 3.1, you then know next time to do it differently. I won't offer suggestions as to what to do differently because wire gauge, inner diameter of the coil, tail lengths, etc. all play factors. I found it best to go slow on the first few, and keep a journal with all the details of each build for reference. By details, I am referring to stuff I just mentioned as factors. That way, you don't have to guess what you did differently between builds and it makes it easier to narrow down what you like the best. In addition to just building the coil, the wicking material will play just as much of an important roll in a good build for you. Silica, Cotton, Ekowool, Hemp, etc. all have different wicking characteristics, and therefor will yield different results on the same coil.

Hope that helps you, or anyone else stepping in to this.

And as always, be safe, go slow, and when in doubt ask questions.

There is a good thread on pro tank coils here http://www.e-cigarette-forum.com/forum/clearomizers/486794-protank-microcoil-discussion.html Also check you tube

I started rebuilding my Kanger heads shortly after I began vaping. Mainly because I was tired of the inconsistent quality of the factory heads, but also to save money. Here is a great thread about how to do it. http://www.e-cigarette-forum.com/forum/clearomizers/396220-kanger-protank-rebuild.html

I now make micocoils and like them much better. http://www.e-cigarette-forum.com/forum/clearomizers/486794-protank-microcoil-discussion.html

Like many other things that you try, it takes a little time and practice before it becomes "easy". Although it not really difficult to begin with.

 

[Weizenheimer]

Before rebuilding them, accumulate a decent number of used ones, then on each pull off the top post, remove the loose wick material on top and toss it, soak them overnight in cheap vodka, rinse with water, dry fire without the top post on until any left over gunk is burned off, replace the loose wick you tossed, replace top post, and reuse. Getting around 15 or some of them will allow you to go months without rebuilding if you follow this cleaning method first.

Some people use them without the loose wick on top. I tried it on a couple, and they worked great until my tanks were about half empty. Then they got gurgly. I put a snip of wick on top and they worked great all the way to empty.

They are not true rebuildables, but people do rewire and rewick them;
I myself dryburn them and replace the topwicks, but not the main wick running though the coil;
Interfering with the coil is too fine a work for me without better setup; easier for me to get a proper rebuildable.
There is a grommet which you pull out and put back in in order rewire; when the grommet fails, that's it unless you got a good substitute for that grommet.

I recommend 2 ohm minimum for learning. 2.5 ohm good too.
30 gauge.
28 would be on the big side; coil would be too big; 32 might be best; but 30 would be easier to start working with.
Get some silica rope, but meanwhile, cotton I have found tastes great!!

for vaping on a budget, consider one of these:

I've been rebuilding ProTank heads for a few months now from the initial new heads that came with the tanks I've bought. I use 30 gauge kanthal and go back and forth between cotton balls and cotton yarn (Peaches & Cream from Wally World). The initial jump in vape quality from my first rebuild was jarring! So much better than the stock heads! And cheaper to boot!

I recently got an IGO-W and have been toying with that. It's really quite easy to rebuild either setup, and the increase in vape quality and satisfaction in knowing I made the coil is well worth the small effort.

 

[Mark Anthony]

I have about 5 boxes of Protank 2.2 ohm coils... I like to keep them as a back up in case I don't have time to rebuild. Normally I'll use the stock coils until they wear out and then keep the shells and rebuild a bunch all at once with organic cotton. The other day I sat down and put my mind to it and rebuilt 20 coils.... It comes out much cheaper and it gives me a nice little hobby as well.
