I have a eleaf ikuun i200 with a Melo 4 tank and it’s supposed to go up to 200.00 Watts. When I bought the vape and used the coil it came with, which was a 0.3 ohm it would go to 200 Watts just tasted Burt when I would try to hit it. So recently I got a 0.5 ohm Coil (EC2) and at first it wouldn’t go past 152.4, I just dealt with it. I recently had to change the coil and again got a 0.5 ohm and now the wattage won’t go past 136.2. I’ve tried changing it when it was fully charged and that won’t work. I don’t know what’s wrong. Help??

It never said it could go up to 200W on any resistance 
Batteries are limited in what they can safely put out and the Ikuun is only allowing what is realistic. If you absolutely need 200W (for whatever reason) there will only be a narrow range of resistances the Ikuun will do that.
Other devices are the same, has nothing to do with Eleaf. All one could say is the advertisement with 200W is rather optimistic.

On all regulated devices, there is an amperage limit the electronics can handle. In short, the higher the ohms, the lower the maximum watts, and the lower the ohms, the higher the watts. There is also the limit of the Voltage. By my guessing, the battery/electronics limits the voltage to 8.2 volts. If you go to Ohms Law Calculator and punch in 8.2 for the volts, and the ohms of your coils, you'll get the maximum wattage.
Also, keep in mind that if the coils are rated at .5 ohms, that is a generalized number. it could be .52 or .49 ohms. So the maximum wattage might vary from one coil to another.
Which leads to my one question... why are you putting so much power into those coils? running it at the maximum power is never a good idea. It will usually lead to burned coils due to dry hits, lower battery life, and just an overall bad experience. If you like a warm vape, I would go back to the lower ohm coil, and see about getting the burning taste out. I have a feeling it's just poor wicking that gave you that burnt taste.

Those coils don't need near the wattage you are using to get a good flavored warm vape. If you are chasing clouds you need a different tank or better an rda and perhaps a battery upgrade.
I'm not familiar with the device but it sounds like you have a mod that actually lets you know whats going on. Most mods will just let you set them to whatever and show that but not produce that output with most loads. As mentioned, these devices control the voltage applied to the coil and therefore the amperage and wattage. Here's a chart from a review I recently did on a Sigelei Kaos Z. This is a fairly typical test result.
You can see proof positive using a O-Scope on the same unit:
Nothing wrong with your mod.

I'm guessing that I agree with you here.
I agree with him.. just don't know about his pics.
Mods have limits. They have limits for all power variables including voltage, wattage, ohms, and amps. Selling a mod by it's wattage limit is only showing you one of it's limitations. If you run into one of the other limitations, it either will not work, or restrain some of the other settings.
In the OP's post, she was using a .5 ohm coil. Assuming it was exactly .5 ohms, we can guess what limit the OP ran into. I saw the Ikuun has a 50a limit, so if I plugged in .5 ohms, 50 amps, it gives me 25v and 1250 Watts... so she didn't hit the amp limit. I put in .5 ohms and 200W, and that would supply 10V to the coil...but she didn't reach 200W, so It left me with the voltage limit. I plugged in 136.2 and .5 ohms into the calculator, and came up with 8.25 volts.. which sounds in line with a typical 2 cell lithium ion setup. Lithium Ion batteries usually have 4.2 nominal charge per cell... two cells in series would equal 8.4, so the math lines up with a voltage limit of somewhere between 8.2 and 8.4 volts.
Thanks for thinking I'm able to understand even half of your post.I agree with him.. just don't know about his pics.

Heh, try heading over to Ohms Law Calculator and plug in some numbers for fun.
As long as you understand that ohms law is just "how things are" and cannot be changed, you start to understand how things work and the limitation of ecigs. I'm just thankful they set a maximum amp limit on mods. I'm just worried they'll get greedy for statistics and sales, and up the amperage cap to 40 per cell and advertise it as a 672 Watt mod... that mod would be dangerous, push the batteries past the limit and see stuff like venting.
Busardo's scope segments on mod reviews, explains the limitations on the devices. Thanks for posting Neal.
Yes the high voltage can be somewhat "fictional" in the sense that if you don't have the right batteries to support that wattage (I don't know of any 18650 pairs that would do it) you aren't going to reach that wattage, period. It does sound like your mod is actually monitoring what it outputs to the coil, I don't understand the details of how that works, either, it's somewhat hazy to me. But, your mod is actually telling you by limiting your voltage that you are SEVERELY overpowering your coil. There is no way on Earth I'd enjoy vaping a 0.5 coil at 137 watts, or whatever your terminal "limit" is. I'd say a more reasonable range would be 20ish (if you are a wattage weenie like I am) to 40--50 watts.
Take a look at your coil. You may need magnification glasses to read it but in tiny letters it should give you the recommended coil range from the manufacturer, which will tell you what wattages are "recommended" for the coil. It's fine to be below them but going above the upper limit is going to shorten coil life often significantly, probably why you are getting that "burnt" taste, etc.
You also need to prime coils, which means wicking by inhaling WITHOUT the fire button and then slowly moving up in say five watt increments (even if there is no visible vapor) taking a few puffs, then increasing wattage again, until you hit a happy place, overshoot it slightly, then move back down to where flavor is best for you although it STILL needs to remain within the recommended wattage for the coil.
"More" is not always better-- for flavor, for your equipment, for your coils and for your batteries. I own a few "overpowered" vapes myself, where I know I will never reach "maximum wattage" and I use them because I like the mod, not because I need 300 watts running through my coils. That type of wattage is neither enjoyable nor safe.
Best of luck,
Anna

Mod manufacturers need a way to encourage potential consumers to choose their latest product over their competitors's latest product. In recent years, that "way" is to advertise ridiculous wattage output because misinformed consumers seem to believe "more is better".
Truth is, mods are limited by the batteries available to run them and by their chip board limits. Manufacturers can exaggerate the truth and rarely get caught in the lie. Segelei got caught with the Segelei 213 and Segelei Fuschai 213. Not picking on Segelei because most Chinese manufacturers over-rate their specs.
This is quite common with the Chinese electronics market. The aftermarket batteries made in China will advertise their battery is 40 amps but when tested it is only a 20 amp battery.

In amongst all the battery information folks have shared with you, I didn't want you to miss the thing that is equally important. Don't try to vape that tank, or any other tank for that matter, that uses "plug and play" coils at 200W, ever. It will very likely fry your wick in a millisecond if not the coil. Start way way low (10-15W) and work your way up to the vape you like, bet it won't be much more than 25W.
Welcome and glad you joined.
Look like you have an answer.
