VooPoo UFORCE Replacement Coils offer crisp and pure flavor from your VooPoo UFORCE vape device by refreshing that old cotton and replacing it with fresh materials. These advanced coils also include anti-leak and anti-spit back technology to keep things clean, and the heat insulation offers a longer lifespan than some traditional coils. Most impressively, VooPoo utilizes OCC coil heads to amp up power faster for a more intense flavor and quick firing.
