that is from levaporz, just order thru his website, i never encounter any problem with them when ordering for now

but it's 1.5 ohm, the vapor sure hot

it is dual coil carto, means 1.5 x 2= 3.0, but in parallel it just 1.5.. not hot lah

no hot la..i'm a loyal dct user.hahaha problem i buang carto place new 1 then fapping again.

bro kalau dari segi maintainance, gune carto sponge ke wick lagi leceh?

Smuggle kut, or maybe thru courier? HAhaha try to ask your friend and let us know

aku tak pernah pakai carto wick.sbb yang sponge lagi senang dpt dr wick.kalau dah pakai carto ni mmg leceh.kena pakai buang.1 carto hanya tahan sebanyak 10ml sahaja.boleh je nak cuci atau besihkan dengan pelbagai cara tapi rasa takkan dapat sama mcm baru la kan...

that wat i rike using carto.. easy to use, easy to maintain, can use the tank over and over until it break

eh bukan karto wick, beza maintenance atty wick dengan carto sponge..tapi karto memang jenis pakai buang eh? kalau macam tu aku stick dengan atty je la

masing2 ada kelebihan dan keburukan bro.

tu la. ingatkan kelebihan je biasenye kalau atty biase ni, berape kerap kene tuka wick eh?

bila dah tak sedap.

Tahu tak kenaper kadang kadang i vape, my throat mengada-ada like itchy, but sometimes it is not...
How come???

try adjusting the voltage? (as if i know how ) or maybe its the brand of the flavour?

dunno. i'm really new at this

itchy ? i would suggest to reduce the voltage if you are on VV or VW.
try switching with another brand of e-liquid and vape at the same voltage as now, see if it does make a change.

Sometimes, e-liquid PV/GV are not as per seller claimed. becareful.

pergh dua2 yg aku teka betol!

Sharing from ECF - from BiffRocko,

Before we get started talking about high voltage vaping though, let’s get one thing out of the way. High voltage vaping is a giant misnomer. We should be calling it high powered vaping. A bit of electronics theory, which we’ll get to in a moment, helps explain why this is the case. For now though, the important thing to know about vaping at higher power are the tangible performance differences.

High powered vaping provides several differences over low powered vaping. Chiefly, higher power produces a hotter vapor and requires less draw to produce an equivalent volume of vapor. It’s similar to the difference between sucking soda through a thin, narrow straw and a fat, wide one. The other major difference is in taste. Some juices have a stronger flavor at a higher power, while others have a stronger flavor at lower power.

A fundamental of electronics, called Watt’s law, is essential in understanding what high power vaping is all about. The best way to explain Watt’s law is by using an analogy.


Let’s imagine a boxer with big strong arms that is capable of packing a powerful punch. Now let’s imagine that boxer punching a heavy bag in the gym. The only thing slowing down the potential power the boxer can deliver is the resistance of the air in the gym. Air being relatively thin means he’s going to hit that bag with a lot of power.

Now let’s imagine the same boxer hitting the same heavy bag, but this time he’s under water. The water offers much more resistance than air does, so even though the boxer’s strength is the same, his punches is going to be much less powerful.

Electronics work in a similar manner. Voltage is potential, similar to the boxer’s strength, and resistance works the same as it does in the analogy. The more resistance there is, the less electrical power that’s delivered given the same voltage.


As usual when dealing with scientific topics, there is a mathematical formula which defines this behavior. This formula is Watt’s law.

Power = (Voltage * Voltage) / Resistance

Knowing this formula is vital to understanding what high power vaping is all about, and helps us gain a better understanding of how the different combinations of vaping equipment perform relative to each other. This is where the term high power vaping comes from. Let’s look at some concrete examples to see what I mean.


Most standard 510 atomizers have a resistance of 2.5 ohms. Mass produced PV’s such as the 510 and the eGo run around 3.2v. Using Watt’s law, we can calculate the power output for this configuration.

(3.2 * 3.2) / 2.5 = 4.096 watts

If we use a standard 510 atomizer, but instead step up to a 3.7v device our power output increases.

(3.7 * 3.7) / 2.5 = 5.476 watts


Let’s see what happens when we step up to a 5v device with the same standard 510 atty.

(5.0 * 5.0) / 2.5 = 10 watts

Now that’s a huge difference. 5v is considered by many to be a vaping “sweet spot.” Having seen these examples, you might think that 5v, with all that power, is the bee’s knees. But hold on a second! What happens when we change the resistance of the atomizer?


Most low resistance 510 atomizers are rated at 1.5 ohms. Let’s see what happens when we use a low resistance 510 atty on a 3.7v PV.

(3.7 * 3.7) / 1.5 = 9.127 watts

Holy high power, Batman! Our 3.7v device with an LR atty is now putting out almost the same amount of power as a 5v device. This is why you’ll see people saying that a 3.7v device with an LR atty simulates 5v vaping. It’s not a simulation at all. It’s just putting out slightly less power than a 5v device with a standard atty. It’s still high power vaping.


You might be asking if high voltage vaping is an incorrect term though. It’s clear that 5v with a standard atty is putting out more power than 3.7v with a LR atty. Let’s look at one more example to see why high voltage vaping is indeed a misnomer.

Some vendors these days are selling what they term high voltage atomizers. These atomizers typically have a resistance of 3.5 ohms. Let’s see what happens if we put a 3.5 ohm atty on a 5v device.

(5.0 * 5.0) / 3.5 = 7.14 watts

Whoops! Now our 5v device is putting out less power than a 3.7v device with an LR atty. The voltage is higher, for sure, but as we’ve learned here, voltage is only part of the equation - resistance being the other. Power output is what’s really determining the performance of the PV.


And that’s about it. Equipped with this knowledge, you should be much more prepared to make a decision about which configuration of PV and atomizer - or cartomizer, they have resistance too - works best for you.

But sometimes from same brand of liquids, some it has that effect
Sometimes not, even from the same bottle, example like i use today, i feel weird, i use tomorrow, i feel okay...
Maybe my problem, hahaha

Haha... never tried dual coil b4. Currently using 1.8 ohm at 4.2v, lotsa vapor but it's kinda warm

do keep track on ur water intake as well bro. someone here has reminded us that vaping can easily dry ur throat. perhaps thats y ure feeling the itch?
