You just installed a fresh coil, primed it perfectly, and took that first hit. Burnt. Again. It's one of the most frustrating things about vaping, and it happens more often than you'd think. The problem usually isn't the coil itself. Most vapers don't realize that wattage settings, e-liquid viscosity, and even how fast you're hitting it can cause that charred taste. If you're chain vaping, the cotton can't re-saturate fast enough between puffs. Running high VG juice through a coil designed for thinner liquids will also cook your wick before you notice. Your Smoke shop Fairfield can help you match your setup to your juice, but understanding why it burns saves you money and aggravation.
