The Bottom Feed (BF) is a box architecture integrating a flexible bottle filled with e-liquid that is pressed to feed the atomizer mounted on the box through its Pin 510 pierced.

This is a practical evolution for fans of drippers (RDA), sprayers without a pyrex tank and only having a more or less deep tank under the coil(s). Before the BF, the dripper had to be regularly fed with Juice, by pouring e-liquid through the drip tip every ten puffs or so.

Thanks to the Bottom Feed, the vapoteur now has a reserve of 6 to 10 ml of Juice in his box. This is a substantial capacity and therefore not insignificant, allowing a sustainable vape. When pressing the bottle, the liquid rises through a small tube and ends up in the dripper tank to saturate the cotton.

Of course, in order to operate a BF box, the atomiser must have a 510 pin drilled in it (the central screw for the electrical connection, which is almost always included in the spares bag). Nowadays, almost all drippers (RDAs) have a BF pin, as do some RDTAs, which will significantly increase - on the latter - the available Juice supply.
