You can test a resistance range of 0.01 – 9.9ohms by screwing your build deck onto the meter via the gold plated, spring loaded 510 connection thread. Like most of the best ohm readers available today, the GeekVape 521 Tab has a test fire/dry burn function so you can fire the coil and test it without having to attach it to your vape mod.
What do ohms do in a vape?
Here are the key points to remember:
- Sub ohm vaping uses atomizers with a resistance of less than 1.0 ohms.
- Also called DL, or Direct Lung vaping.
- Use regulated mods, mech mods are dangerous.
- Use sub ohm vape tanks as opposed to building your own coils.
What does ohms mean on a vape?
What does ohm mean in vaping? Ohms are units of resistance. The lower the resistance of your atomizer, the larger the amount of current flowing through it. If you increase resistance, the atomizer receives less current. Does higher ohms mean more power? A Simple Explanation for Vapers. An ohm (Ω) is a unit of resistance.

How to tell if your vape coil is bad?
How to prime vape tank coils
- Take a new coil out of the box
- Drip some e-liquid on the wicking holes and inside the coil head (3-4 drops will do)
- Assemble your tank and fill it with ejuice
- Screw your tank on your mod and set aside for 10 minutes
- Inhaling on the tip of the tank without firing will speed up the process

How many ohms Should a coil read?
You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, a little less is ok but no more.

How do you know if the coils are bad on a vape?
Experiencing a "Burnt" Taste in Your Mouth This is hands down the most common sign that your coil has gone bad. When you're vaping with a coil that needs replacing, you'll experience a burnt taste no matter what e-juice you use or what modifications you try to change.
How do you fix ohms on a vape?
You could try the following methods to recover: Please take off the tank and click the fire button, and then place that tank back on, click "n" when it asks "is it a new coil". 2. Please make sure screws are tight on the tank if you use the RBA coil on your mod.
What does a reading of 0 ohms mean?
Resistance, symbolized by the (Ω) symbol and measured in Ohms, is a measurement of how well a current can travel through a circuit or a given path. A circuit with no resistance (0) would indicate a complete circuit, or one that has no short.
What tool should be used to check resistance?
Resistance is measured using an instrument such as an analog multimeter or digital multimeter. Both types of instrument can measure not only resistance, but also current, voltage, and other parameters, so they can be used in a variety of situations.
How long should a vape coil last?
between one to two weeksA new coil should last between one to two weeks. However, most e-liquids leave a thin layer of residue when they are vaporized. This builds up around your coils and wicks and can end up clogging your device in the long run.
How long should mesh coils last?
between one to two weeksGenerally, new coils last between one to two weeks, but that can be extended if you properly break-in new coils when you get them and practice good care and maintenance procedures during and between usages.
Why is my coil burnt after 2 days?
That burnt taste can occur if there's not enough e-liquid on the wick inside your atomizer coil. The wick is the part of your device that soaks up the e-liquid, which is then turned into vapour when the coil heats up.
Why does my vape say ohms low?
Error messages about ohms are specifically related to the resistance of your coil(s) and indicate that a coil is not compatible with the device. Typically, pairing the proper SMOK-branded coils with your SMOK device is the easiest way to fix this problem.
What does it mean when the ohm is too low on a vape?
'Ohms too low' or 'ohms too high' error message This SMOK warning refers to the resistance of your coil. Most SMOK users will use coils that are made by SMOK so they should not have this problem. If you have a rebuildable atomizer (RBA), it could be that the coil resistance is too low or too high.
What wattage should I vape 0.15 ohm?
60-90 wattsIn contrast, the 0.15ohm dual mesh coils have a best recommended wattage of 60-90 watts. Both atomisers offer huge clouds and flavour production. Since these coils are sub ohm / direct to lung (DTL) in vaping style, they are recommended for use with higher VG e liquids.
What is an ohm in vaping?
What is an Ohm. First of all, ohms represent a unit of measurement for resistance, and when it comes to vaping they translate to how difficult is for the electrical current from the battery to pass through the heating coil. The lower the resistance, the faster a coil heats up to a certain temperature and controlling this value is key in delivering ...
Why are above ohm vapes so popular?
The reason for which above ohm resistances remain popular with mouth to lung vaping is due to the restrictive draw these devices can offer and the similarities with actual cigarettes.
How low can coils go?
The coils today can go as low as 0.15 Ohms (in the case of Kanthal) and there are mods out there that can fire even lower so technology is no longer a problem. Also vapers have discovered that by twisting two or more types of wire together they can create complex coils like 'twisted', 'claptons', 'fused claptons' and 'alien claptons' which in terms give an even better flavor.
What starter kit comes with coils?
On some of these devices you can also experiment with sub ohm coils, which are either included in the box as spares or can be bought separately.
What resistances do you use for vaping?
People who prefer mouth to lung vaping are usually the ones who use standard resistances (above the 1 Ohm limit) and those who prefer direct lung inhale use sub-ohm resistances (below the 1 Ohm limit).
Why do you need a sub ohm coil?
Because it vaporizes a lot more e-liquid, together with the big clouds, it also delivers a bigger quantity of nicotine. This is why, in most cases, if you're used to vaping on 12mg for instance, switching to a sub ohm coil directly implies lowering the concentration to 6mg or even 3mg. Taking a 12mg puff on a 0.3 Ohm RDA could make you feel very light headed so if it doesn't feel right, go for a lower concentration.
What is temperature control on a mod?
Many of the newer generation mods offer a feature called 'temperature control', which works with Nickel or Titanium coils and gives the user the option to set a desired valued between 200 – 600F. These coils generally have a sub ohm resistances and fire as low as 0.05 Ohms. Because the user can set a desired vape temperature, it has total control on how cool or warm he or she wants the vapor to be, and the feature also prevents dry hits.
How many amps does a 0.20 ohm coil need?
For example, a 1.0ohm coil only needs 14W & 3.7 amps to achieve a voltage of 3.7V. But a 0.20ohm coil needs 68.5W & 18.50 amps to achieve the same voltage of 3.7V. A lower ohm build will in turn lead to shorter battery life.
What does V mean in vaping?
V: Voltage. This is the voltage of your battery. When fully charged, a single battery will have 4.2V. As the battery is discharged, the voltage will drop. It’s helpful to think of voltage as “electrical pressure”. In an electrical circuit such as your vape, voltage would be like the water pressure in a hose. High pressure can provide more flow than low pressure. The higher the voltage, the higher the potential amperage.
What is Ohm's law?
Before you start building your own coils to put into your vape tank, you should know Ohm’s law. Whether you’re using a regulated mod or a mechanical mod, Ohm’s law gives you essential information about the limits of your build that will help keep your vaping experience a safe one. Ohm’s law is essential to vaping because it determines the amount ...
Why is Ohm's law important?
Ohm’s law is essential to vaping because it determines the amount of amperage and wattage that your build will output which in turn determines if your build resistance is within safe limits for your battery. When these limits aren’t understood or respected is when batteries can explode.
Why is there no wattage for vaping?
There is no ‘best’ wattage to vape at because it all depends on the resistance of your coil. A lower resistance coil will require more wattage than a higher resistance coil to achieve the same vape. It really depends on how hot you like your vapor to be.
How many ohms are in a 0.42 ohm battery?
Using two 0.42ohm coils would come out to 0.21ohm, within the safe limits of a battery rated at 20A.
What does R mean in a battery?
R: Resistance. This is the resistance of your coil in ohms. A lower resistance coil will draw higher current (higher amperage) from your battery. This makes calculating resistance essential for building within the safe amperage limits of your battery.
How many ohms does sub-ohming vape have?
Sub-ohming takes this further by vaping at a resistance of less than 1 ohm.
What coils are used for vaping?
Coils below 1 ohm are common, and coils with a resistance of 0.8 ohms are often used for Mouth-to-Lung vaping. Even lower resistance coils, such as 0.15 coils, are often used for cloud vaping. Originally, sub-ohm vaping was reserved for experienced vapers who want to push the boundaries with rebuildable coils.
What Ohm Resistance Should I Use In My tank?
When we first wrote this post, we used to refer people to the chart above.
How to get the perfect vape experience?
After all, with most entry-level vape kits, all you need to do is: Check what wattage you can use with the coil in your device. Adjust your wattage and airflow until you get the vapour, flavour and throat hit you need. Some people want to know more to get the perfect vaping experience.
How to get a vapour hit?
At its simplest level, it’s simply a matter of adjusting the voltage or wattage of the battery until you get the vapour, flavour and throat hit you desire. You can also experiment with using different resistance coils and combining them with different voltages/wattages.
Why do vapes burn out faster?
You will need to increase the voltage to increase the wattage and get a better vape. Because lower resistance coils use more wattage, they tend to generate more heat. This means they often burn out quicker than a higher resistance coil would.
What affects vapour and throat hit?
The resistance of your coil is not the only thing that affects vapour, flavour and throat hit. It also depends on the amount of power flowing through your coil. There are two common types of vape batteries which allow different amounts of power to flow through your coil. These are variable voltage and variable wattage.
How to test coil resistance?
If you do want to use a multi-meter to test your coil resistance just make sure to set the meter to the lowest ohm setting (usually 20). Then test the resistance on your meter probes by touching them together. Remember this resistance as you’ll need to minus it off the final read out when you test your coil.
What is the cheapest ohm meter?

On most units you can also crank down the voltage and get standard ohm hits. 0<1 less than one-ohm standard.
How many watts does a standard ohm vape pen use?
Standard-Ohm vape pens will typically power on under 10W. These Vapes are super efficient and great for beginners. Common features include:
Do you need to vape at high power?
Tip: Just because your Vape Pen goes to a high power setting... it does not mean you need to vape at that setting. Generally speaking, lower temps will produce cooler hits, save battery, and create less smoke.
Does an adjustable vape pen increase wattage?
If you have an adjustable vape pen a higher voltage will increase your wattage, drain your e-liquid supply and reduce battery life. The benefit, however, is more smoke and more flavor (although some flavors do better at a lower power setting.)
Do standard coils use sub ohms?
Note: Don't be tricked! Some Standard-ohm coils use Sub-ohm parts. Look at your wattage.
