The first question in reality is "What the devil is an Ohm?". What is being referred to here is the ohms for your e cigarette clearomizer or similar vape tank device. Before you delve into the deep dark recesses of the internet in order to be told by fans or so-called experts what the correct ohm is for you, please remember that everyone is different and everyone has individual likes and dislikes when it comes to vaping. It would be a very boring world if we didn't.
What you need to do is to read on and work out what the best ohm is for you in an informed way and with some trail and error.
What Is an Ohm
The ohms level is a way of measuring a level of electrical resistance. The standard or regular level of ohm when it comes to vaping and your clearomizer is between 2.4 and 2.8. This is by far the most common ohm range chosen by those looking for replacement coils, with the most commonly chosen being 2.5. This standard level tends to offer the most consistent level for your vape.
What's The Difference between Ohm Levels When Vaping?
The actual difference between a low ohm and a higher one in terms of actual smoking enjoyment and preference is laid out here:
A Lower Ohm Coil
When you use a replacement coil with a lower ohm you may expect:
• A warmer vapour
• Often more vapour (more heat via the coil creates more vapour)
• A dry hit (burning)
• Your e liquid will be used up more quickly
• Lower Ohm coils may result in premature battery failure.
Higher Ohm Coils
Using a replacement coil with a standard or higher ohm will likely:
• Result in slower battery drainage
• Use less e liquid as compared to a lower ohm level
• Provides the user with a cooler vapour
• Produce less vapour due to there being less heat at the source (the coils).
Clearly both levels have their pros and cons which is why most new e cigarette devices come with the standard 2.5ohm level. This gives a vaper a chance to get to grips with vaping before experimenting in order to find the optimum level for their own enjoyment. The best way forward when looking to perfect your vape is to simply try different resistance levels and see how you get on. It really does depend entirely on personal preference and so there is no "best" or "worst" ohm level, it all depends on what you are looking for in your vape. It might be that a standard ohm coil is perfect for you or it might be that you are looking for more vapour. You might want more vapour yet find a burning taste off-putting as this may occur with some low ohm coils, hence the trial and error.
Other FAQ Regarding Ohm Levels
What Levels are High/Standard or Low Ohm Exactly?
Usually a low ohm coil would come in at between and 1.5 and 1.8 ohms. A standard coil would be around 2.4ohm and 2.8ohm and the higher ohm band starts around 3.0 ohm. There are slightly higher or lower resistance levels for coils however these are much less common as they are specialised items, often used by very experienced vapers who look to customise their e cigarettes fully.
I Have a eGo Battery (Standard) So What Ohms Do I Need?
The first step when choosing replacements would always be to follow manufacturer and retailer instructions regarding new coils. Going outside the specified ranges would cancel any warranty and might prove dangerous.
That said, generally speaking this type of eGo battery would take anywhere between 1.7 and 2.8ohms as standard. This will allow for a perfectly acceptable and enjoyable usage.
What Are The Downsides of Lower Ohms?
There are drawbacks as well as benefits to using lower ohm levels, many of which are detailed above. The important thing to remember is that choosing particularly low resistance levels of ohms is that there is often a trade-off. You will enjoy more vapour which is great if that's your thing however the higher heating levels tend to result in coils being used up more quickly, e liquids being used up faster, burnt-out wicks (not pleasant) and additional stresses being placed on the battery. Quite a few downsides actually however it's all about balance and finding the right low ohm coils for your device if this is what you're looking for in order to enjoy the benefits.
Do Different Ohms Have an Effect On Flavour?
While lower ohms are known to produce a more impactful vape this doesn't necessarily mean it is more flavoursome. How flavoursome a vape will be will depend mostly on the type, brand, quality and flavour of the e liquid. That's not to say that heating an e liquid at different speeds / temperatures won't have a subtle effect on the end result however it is unlikely that the ohm level would have a substantial effect.
What About Very High and Very Low Ohms?
If you are reading basic FAQ about ohms now is probably not the time to (yet) be experimenting with ultra high and low coils or modifying your device to this extent. Many people once they've been vaping for a while decide to experiment with lower ohms especially in the region of 1.0 to 1.4ohm. Caution must be taken when modifying to this extent and it is not recommended by manufacturers.
This is a basic intro to the difference between ohm levels and their pros and cons. Your best bet is to start off with standard / factory default levels and experiment carefully from that point on. Always read and take into account manufacturer instructions and safety guidelines though to protect yourself and your warranty.
