The pod has a capacity of 2ml of the nicotine salt e-liquid, which is a decent amount for any pod to hold as it will allow you to take more than the 400 puffs every time whenever you fill it up to the max. The adjustable mouthpiece will let you customize the airflow for your most preferable style of vaping. There is a resistance of 1-ohm as well as the Kanthal heating. Also, there is some Japanese cotton in them so that it can really absorb a ton of the vape e-juice that you fill-up the pod with. in every pack, you will receive 2 pods so that if once you make this purchase then you might not have to make another one anytime soon. Also, it is recommended to allow each new Orion Q pod to sit for 15 minutes before its use and therefore, you can also fill or refill your pod with your choice of e-liquid by simply unscrewing the cap at the top of the replaceable refill of the pod.
