Disposable vapes are ready to use out of the box because they are not only pre-filled but have pre-charged batteries. Many popular and longer lasting disposables have a type-C charging port. This combines portability with a high puff count and a pre-filled e-juice capacity in excess of 10ml.
A high-capacity disposable vape holds enough e-liquid to last many days, and the battery size is generally sufficient to make it through a solid day of vaping or more before recharging is required.
Puff Counts
There are disposable vape designs that do not requiring recharging, these generally are shaped more like vape pens and top off at 6ml and 3000 puffs.
Customers are often on the lookout for the device with the best puff count. Puff counts are determined by coil resistance, and e-liquid capacity. The longest lasting disposables can be rated for upwards of 8000 puffs. These of course are estimates, as a tiny puff or an 8 second inhale consume vastly different quantities of e-liquid.
Unless it has an extremely large battery size, a disposable vape pen will usually generate a puff count of around 3000 with a capacity of about 6ml.
You will know when the disposable vape pen is empty or 'dead' when either flavor begins to subside, or when an indicator light begins to flash. Disposables do not have advanced chips like refillable pods and sub-ohm mods, and their flavor and performance will fade as the battery drops below 25 percent. This was a big headache with the classic disposable vape pen, but rechargeable models can be quickly rebooted.
Rechargeable Disposable Vapes
There has been a technological convergence and the most popular disposable devices are currently shaped like a compact lozenge, fit in the palm of your hand, have a small mouthpiece offset to one side, and are USB-C chargeable.
Distinct brands and unique flavors are the most obvious distinguishing feature. Colorful packaging can also catch the eye, which matters when so many convenience stores carry disposables next to the tobacco and menthol flavored pods of the Big Tobacco giants. Some modern disposables can measure the remaining charge and e-liquid level, which is no small deal when dealing with a device holding 16ml of e-liquid rather than a 5ml disposable vape pen or 2ml stick bar disposable. But if you are using your disposable device daily, a rechargeable model with its convenient size, fast recharging, and long-life probably makes more sense.
