Advken CP TF VS GeekVape Zeus (Single coil)
The deck:
It is easier to place a coil in the Advken CP TF than Zeus however there will be a problem if you plan to use lengthy coil due to the layout and size of the juice well.
In a way, if your coil is longer than 5.35mm it will overhang the juice well, thus make it difficult to cover the inner part of the big juice well.
For non-space Clapton coil the most it can go is 5 wraps
I think a 4 wraps spaced Clapton coil might fit without overhang. For plain wire coil, you can probably have 1 additional wrap compare to the Clapton wire's.
I prefer the juice holes design of Zeus. Even though placing a coil (with less wraps) in the Advken is much easier than the Zeus, but come to wicking, it is just the opposite.
The Chamber:
Advken's chamber though looks smaller than the Zeus, but it is a surprise to me that it allows a rather high placement of coil. I use the coil come in the box directly, no cutting nor trimming at all and guest what, no short, it just work!
Advken's chamber is removable. When the base is screwed back to the tank it press fit and holds the chamber's position. At first I was thinking that will be an advantage because it means I can easily take the chamber out and clean it when I re-wick, but I was wrong! I simply can't, as long as there are still juice in the tank. Man... the chamber is part of the structure that holds the juice.
Air Flow:
Advken has tighter AF than Zeus. I compare them with both their AF control open fully.
Flavor:
I don't really find Advken produces better flavor quality than the Zeus. Their flavor quality are close IMHO.
Conclusion:
Stick with Zeus single coil, there is no obvious advantage in the Advken CP TF over Zeus.
May be buying a coil trimming tool is a better thing to do.
