...I hear that 4.5 ohms should bring this down to 5 volts...
You heard right. [NOTE: If you like, you can skip the following paragraphs in blue text. They are useful in
understanding all this watts/amps/volts/ohms stuff, but not necessary to
find a 4.5 ohm atomizer.]
It all has to do with Ohm's and Watts Laws:
This looks more complicated than it actually is. You can just pick the formula you need for a particular purpose. For example:
Power (watts) = Volts X Volts / Resistance (ohms)
Notice that an increase in battery voltage can be balanced by an increase in atomizer resistance. A 4.5 ohm atomizer on 6V will yield about the same power as a regular 510 atomizer on 5V.
To understand the burning up of atomizers, we turn to another formula, which considers the current running through the atomizer:
Current (amps) = Volts / Resistance (ohms)
Atomizers are very delicate and can withstand only a modest current. Regular atomizers were designed to be used on 3.7V batteries (although the 510 battery is really only 3.2V). Increasing the voltage to 6V needs to be balanced by increasing the resistance of the atomizer.
[NOTE: Higher ohm atomizers are called "HV" (high voltage) because they are intended for use on higher voltage mods, but, in fact, they are high resistance.]
As Houdini indicated, NHaler sells a wide range of HV attys, both
4.5 ohm 510 atomizers and
4.5 ohm 901 atomizers.
NHaler
also sells
5.2 ohm 510 attys. These are intended for use on 7V+, but can be used on 6V: not everyone likes a "5V" experience.
Many other suppliers sell "HV" atomizers. However, some don't specify the specific ohms of the atty. Those who do include IndyVaporShop (
4.2~4.8 Ohms 510 and
4.7~4.9 Ohms 901),
EastMall (4.5 ohm 510 and 901),
Ecigsupply (3.9~4.5 Ohms 510), and
VaporKings (4.4~4.6 Ohms 901). I encourage my fellow veterans to correct or expand on my explanation of watts/amps/volts/ohms stuff and/or provide additional sources.
