SQ is what the company making the Dead Rabbit RDA, which is a dripping atomizer, decided to use to differentiate the bottom feeding version of the RDA. Squonking is using a mod that has a juice bottle built in, squeezeing the bottle and sending juice up the tube into the RDA. It's kind of reverse of dripping, where you carry a bottle of juice around and drip into the RDA. Both ways have their advantages and disadvantages.
This is one of the squonking mods I use. It uses an 18650 battery shoved into the aluminum under the fire button. The hole cut out lets you reach grubby fingers or paws around and squeeze / squonk the juice bottle mounted directly under the connector for the RDA. This is a mechanical mod, no wires or circuits to get all fouled up, simple.
The term squonk comes from the sound of the juice after filling the wick of the RDA, going back down through the RDA's 510 pin & the air, pressure released from squeezed the plastic/silicone bottle. There's also other less polite explanations for the term squonking but I'll just let those get found out if you really want and go looking yourself. *chuckles* I like dripping but at the same time don't want to have to carry an external bottle, just seems kind of redundant, silly to me. Don't care much for tanks now either so, squonking it is for me.
Dripping / RDAs versus Tanking / RTA ... I really cannot say one is better or worse, only from my own view. Tanks didn't give me flavor but I have limited sense of taste and congenital anosmia. Besides that I'm not exactly a cloud chaser but yes, it's nice to halfway fill a room with vapor on exhale at times. I like the texture of vapor which might seem a bit odd. Tanks hampered that as well. I also get good direct lung hits from an RDA. I could do lung hitting on tanks but it was a bit troublesome in the doing.
THANK YOU
for the wonderful an simple explination. CUZ that makes sence
