Squonk... I now have 3 single battery squonkers so will be looking for something with a bit more power either 2x18650 regulated or maybe lipo?? and I'm tempted to pick up a coilmaster ohms tester... the big one... I keep breaking the cheap little ones that cost £5-7. My coppervape squonker is nice but I seem to change the battery when it gets down to 70% as it becomes weak... maybe I'm not being daring enough and reducing my coil resistance?? I've just made up another 1.8L of juice (in addition to the 900ml of custard I have left)... so I should be good for juice for a while Edit: been looking into the squonkers and it seems like the drone may be the answer.. PM me if you see one at around £105 - £110 in a tent somewhere! or possibly the geekvape gbox s100 although it seems to be discontinued... may be a gearbest purchase after vapefest but pm me if you see one at around £50.
