A pod is a piece of hardware that is used with pod kits. There are two pod systems - refillable pods (open pod systems) and prefilled pods (closed pod system). Below is a brief explanation of the two:

Refillable pods

A refillable pod is a small piece of hardware that can be attached and detached from your pod system. They are called refillable pods because you can continue to refill your pod with e-liquid until it needs to be replaced. 

Prefilled pods

Prefilled pods are pods that are prefilled with e-liquid. They often come with the pod kit and are disposed of after all of the e-liquid has been used. They are called closed pod systems because they are not intended to be refilled. 

A pod vape is a small, lightweight vape device. These pod systems are considered ideal for beginners and those who are looking for a compact MTL device for on the go vaping. However, many more advanced pod vapes also provide sub-ohm vaping too for those looking for bigger clouds.

Pod kits and vape mods are very different from the design to their purpose. Pod kits are designed for new vapers, sporting simple to use designs with minimal buttons. The pod system is intended for ease of use as there is no fiddling around with coils. You simply replace the pods themselves that have everything already installed. Pod kits are often both draw activated and button activated.

Pod mods are often a lot chunkier, and have many more settings and design aspects to them. More experienced vapers who want to personalise their vaping experience may opt for a mod over a pod kit due to the range of customisation that is available. In terms of design, they do not use replacement pods like pod kits do, but instead utilise tanks. They are designed to create large amounts of vapour and are best for vapers who want a DTL vaping experience.

This is a hard question to answer as it really comes down to your own personal vaping habits. The more you vape, the sooner your pod vape will need a replacement. However, standard use with most vape pods lasts around 3-4 days.

There are a few important signs to look out for when it comes to knowing when to replace your pod. A burnt taste is one of the most noticeable signs that it's time to replace your vape pod. There can be a varying degree of taste or harshness when it comes to this, and it's a wise idea to do it as soon as you notice the burnt flavour to prevent any damage.

Another sign that a replacement is required is when your vape is producing very little vapour and flavour. You may even be getting dry hits, causing you to cough. If this is the case, it can mean the coil is burnt out or that there is little e-liquid left in your pod.
