Disposable vapes are a great way to vape safely on a budget. A common question asked is “How can I tell when my disposable vape is empty?” Though deceivingly simple at first glance, figuring out just how much e-liquid is left in a disposable vape can be tricky - here are some tips.

• The Vapour Tastes Burnt

It is not uncommon to find the battery life of a pre-charged disposable pod vape lasts longer than the amount of prefilled e-liquid. The characteristic burnt or charred taste of the vapour is caused when there is insufficient juice contacting the heating element or coil causing the element to overheat and burn. This causes any vapour produced by the disposable vape to taste burnt and is the most obvious sign that the disposable is empty.

• Thin and Tasteless Vapour Production

After extended use, one will notice a thinning out of the vapour a disposable vape device will produce. A significant reduction in vapour means it is running empty on e-juice, or e-liquid. It is not empty enough to burn the wick or create the signature burnt flavour, but thin clouds are a sign of lowered levels of e-liquid. You are almost out! 

• Puffing Away but Still No Vapour

If it gets to the stage where there is no vapour production at all, this could signify the following 2 possibilities: 1. Depending on the model, the device might still feel warm and LED lights will power up when you take a draw, as the long lasting battery life usually outlasts the amount of prefilled e-liquid. An empty disposable vape without E-liquid remaining will still power on, and heats up - but doesn’t produce vapour. 2. The other possibility is that the battery and e-juice have run out at the same time. A flat battery means no power to heat the coil and no way to make vapour. 

Conclusion

Experienced disposable vape users are pretty comfortable with guesstimating how much e-liquid is left in their vapes. Whether it's a mental count of how many puffs they have taken, or guessing simply by weight or amount of vapour production during each puff of the disposable vape - firstly understanding how disposable vapes work to produce vapour is the best way to gauge how to tell when a disposable vape is nearly empty. As a rule of thumb, always keep a new spare ready to go, so you never run out of your favourite vape completely!
