Here we’ve got an authentic Kanger T4S with 510 threading. I thought these were primarily 808-D threaded, so I was happy to see them in 510. I really like the size of them.
Unlike most other kanger tanks, these are top coil rather than bottom coil – kind of like a baby Vivi Nova.
The thing I like about these devices is they are super portable, easy to fill, and the cap screws on to keep everything secure and leak free.
