What is a Disposable Vape

A disposable vape pen is a single-use vaping device. It comes already charged and prefilled. All you do is inhale and it starts working. They are perfect for former smokers trying to switch to vaping. They come in hundreds of flavors and are a perfect introduction into the world of vaping.

How To Tell When a Disposable Vape is Done

If you are new vaper it might be difficult to tell when your disposable needs to be replaced. However, there are some signs that will tell that the disposable’s life is nearing its end. Signs include the vape juice tasting burned, the vapor that it creates becoming thin, and or the disposable not creating any vapor. In the following sections, we explore all the signs that will let you know when a disposable is done for.

Sign 1: Vape Juice Tastes Burned

One of the clearest signs that a disposable is at the end of its lifespan is if the vape juice tastes burned. This occurs when the quantity of vape juice is getting low and it no longer has liquid. The coil tries to heat up the now dry wick, and burns the wick instead of evaporating the vape juice. Since most wicks are made out of cotton, you get that nasty burnt taste of dry cotton mixed with the remaining e-liquid inside the disposable. If you experience this burnt taste, it’s time to replace your disposable vape pen. 

Sign 2: The Vapor is Thin or Has No Flavor

When the disposable vape device creates very thin vapor, that’s a sure sign the vape juice is almost out. If the vapor isn’t as thick as it was, it’s time for a change. Thin vapor usually means that the vape juice is low but not low enough to burn the wick. If you notice that the vapor is getting extremely thin but is without the burnt taste, change your disposable. The last thing you want to do is inhale the fumes of burnt cotton. 

Sign 3: Battery Works But No Vapor is Produced

Another thing that could happen is that the battery works but no vapor is produced. This happens when the vape has gotten noticeably warmer, meaning the battery-powered coil is working but no vapor is being produced. This could be because the wick, which is made from mesh (or metal), won’t taste like burnt cotton.  Most likely the vape juice has run out. Throw it away and buy a new disposable. 

Sign 4: Nothing Happens When You Inhale

If you inhale and the device does not get warm, it means the coil isn’t evaporating the vape juice. Most likely the battery is dead. Unfortunately, there isn’t a lot you can do with a dead battery. This is for a number of reasons. A charged battery can lose charge if it’s not used enough. So if you for example you use the disposable vape only a few times with days in between, the battery could have drained. The opposite is also true; if you use your disposable vape pen too often, the battery will lose charge more quickly.

Sign 5: How Many Puffs Does the Vape Have?

An easy way to tell if a disposable vape pen is almost done is by checking how many puffs it comes with. This, is mostly found in or on the packaging. On average, most disposable vapes come with 200-400 puffs, but there are disposables that have as many as 2500 puffs. If your disposable is on the lower puff range, it might only last a weekend or a couple of days,  while 2500 puffs can last 4-5 days. Still, it’s also subjective depending on how much you vape and how frequently.


As you begin to buy more disposables and find your favorite brand, you’ll eventually get a feel for when a vape device is on its last legs. And while this comes with experience and practice, the signs listed above serve as good starting points to know when a disposable is on its way out.
