Here's a dripper's tip that works with single coil RDAs, or dual-coil RDAs with the coils off-center but on the same side.
Keep your coil raised off the deck, but the wick on both sides touching it, going around the entire circumference of the deck. Leave the ground lead of the coil longer and use it to pin the free ends of the wick down against the bottom.
Then you can control how wet your coil gets by tilting the mod:
- If your mod is almost horizontal (and with an off-center coil, the coil pointing up), the juice will pool along the side of the bell. The coil will be above the surface of the juice, or just grazing it, and will feed through the wick. Obviously you want the air hole pointing up also, to avoid a massive leak.
- If you feel the vape getting dry, straighten the mod, so whatever juice is left touches the bottom of the coil directly - or at least wets bits of the wick that are closer to the coil.
With this trick, you can drip 10, 15 or even 20 drops in a small atomizer without flooding it, and you can even out the quality of the vape throughout the juice charge, all the way to the end, right before you need to recharge. Just make sure you put down your mod air hole up to avoid leaks, and you finish the charge before sticking it in your pocket for the same reason
