Designs can vary greatly from pod to pod. Some designs are top-fill, others are bottom-fill. The vape industry is constantly evolving so new, more high performance designs are constantly coming out. For example, many modern pods have secure anti-leak protection and/or child-proofing mechanisms.
However some general guidelines to refilling a vape pod are as follows:
1. Use an eliquid bottle with a precise dropper to fill the pod accurately.
2. Don’t overfill your pod, respect the marking at the top to avoid spillage.
3. If spillage occurs, simply soak up the excess vape juice with a paper towel and blow through the air hole to clear any additional obstructing eliquid.
