As said above, youtube is your friend. Spend some time wrapping, burning, and rewrapping coils until they come out real nice every time. Kanthal is fairly cheap, and once you can wrap a good coil the coil itself can last for months with weekly rewicking. If you spend two hours practicing coils you will get really good really quickly. The biggest piece of advice I can give, that hasn't been mentioned yet, is to ignore coil building videos that "tidy up" sloppy, poorly rolled coils by heating them up after they're on the atomizer. It is NOT hard to roll a good coil from the start and the better the coil is BEFORE you put it on the RBA the better it will work when all is said and done.
Note: I still tidy up my coils via heat and needle nose pliers, but not nearly to the degree I see some people on youtube doing it.
A watt is a measurement of how much work is being done by the electricity. It is a different way to measure than volts.
If you have an ohm meter, you'll be fine. Figuring out how you like to wrap is half the fun
Agreed. When I first started I found that wrapping parallel coils was easier for me than normal single strands.
