Ok so I did my first VV copper mod, Material used: 1- 4" piece of 3/4" L-type hard copper tubing, two 3/4" hard caps for the ends, vv kit from madvapes ( Thanks breaktru ) 510 gold battery connector, blue led, 20 awg stranded wire, 3 amp temporary on/off switch, 5V-2amp 120 v ac to dc wall adapter, 3/8" brass insert for 3/8" poly supply tubing for the cord to go through and a Zurn control stop button cover for some bling bling
. I used the wall adapter because that's all I had, I also use this mod only at home or in the car ( power inverter )I see no point in using batteries when I'm 2 feet away from a wall outlet. I can really appreciate the work that goes into making a vv copper mod, It's somewhat of a challenge getting all that in such a small space.
