The RPM80 Pro comes with two coil options in the package:
- A 0.4-ohm RPM coil rated for 25 watts
- A 0.17-ohm RGC coil rated for 40-80 watts
Other optional coils start from as low as 8 watts for MTL vaping and there are currently five MTL and four DL coil options, as well as two RBA decks for it—which is great if you want to rebuild your own coils instead of buying new ones.
I tested both included coils with 70/30 3 mg juices. found the 0.17-ohm best around 55-60 watts with the air about 1/4 open, and the 0.4-ohm best around 25 watts. Flavor was good in both, on par with the better mid-wattage DL tanks on the market.
Unfortunately, coil life on the 0.17 was disappointing. I only managed to go through 30 mL of juice before it burned out. The 0.4 coil though had great life and lasted through about 80 mL for me. That, along with the much better battery life that comes with using the 0.4-ohm coil due to the lower watt demands (25 watts vs 55-60 watts) make it a much better option for the Pro.
Overall, the RPM80 Pro is a really good performer with the 0.4-ohm coil, and I really like having the option to buy RBA decks for it
