I dont get it

why do you need more power for a lower ohm coil head? I would think it would be the opposite. Im referring to joes sigelei tank advertised on his blog. It comes with three coils and the reccomended wattage is higher for the lower ohm coils

You don't need more power. The guidance references that the lower ohm coils can run at a higher wattage/power.

It's not a necessity.

Why can a lower ohm run at higher power then a higher ohm??

The lower the ohms, the less resistance.
The thicker the wire, the less resistance.
The less resistance, the longer it takes to heat up with the same amount of power as a coil with higher resistance.
The more power, the faster it heats up.

Generally speaking, lower ohm coils are made with *thicker* wires which offer less resistance to the power traveling through them. If the coil gets too hot too fast, it might evaporate the liquid faster then the wicks can supply it and you'll get dry hits. The thicker wire can support more current without overheating and/or breaking since it has more mass.

What zaroba said. The lower ohm coils usually use thicker wire. Takes more power to heat more metal to the same temp.

Another way of putting it is...

Lower resistance lets energy flow through the coil faster so you need more energy to get the heat you want.

Higher resistance slows the flow so the energy "backs up" and you need less to reach the desired temperature.

Thanks guys!!!
