Bottom Feeder – What is it in Vaping?

Definition

A Bottom Feeder is a type of Mod“>Box Mod that stores e-liquid in a soft, squeezable bottle inside the device. When you press the bottle, juice travels up a tube and saturates the Coil“>Bottom Coil or Deck“>Build Deck from below—hence “bottom feeding.” Its purpose is to deliver fresh liquid directly to the wick without removing the atomiser, making dripping-style flavour and clouds more convenient for Australian vapers on the go.

Technical Details

Bottom Feeders use a 510 centre pin with a hollow “squonk pin” that screws into the RDA. Typical bottles hold 7–12 mL of e-liquid and are made from food-grade silicone for easy squeeze-and-return action. The Batterysection is usually a single 18650 or 21700 cell, though dual-battery squonkers exist for higher wattage. Variations include:

• Mechanical Bottom Feeders – direct output, no circuitry.
• Regulated Bottom Feeders – variable wattage, safety protections.
• Vertical Coil)”>BVC (Bottom Vertical Coil)-ready RDAs – designed for squonk pins.

Usage & Tips

Press the bottle gently until you see a tiny pool of juice on the Build Deck; over-squonking causes spit-back. If you get dry hits, check that the squonk pin is tight and the wick is thinned. Keep spare bottles clean to avoid flavour ghosting. Always lock or turn off the mod when refilling, and use married Battery pairs in dual squonkers to stay safe under Australia’s vaping regulations.

History & Context

The concept emerged in the late 2000s from hobbyist forums seeking dripper flavour without constant dripping. Mass-market Bottom Feeder mods arrived around 2015, and today they dominate Australia’s rebuildable scene alongside regulated squonk kits.
