Vape Pen Troubleshooting

When screwing the cartridge onto the battery, be careful not to overtighten. Just twist until snug, otherwise you may have connectivity issues.

A common issue that happens with vape pens, sometimes as a result of being overly tightened, is that the metal rings that conduct electricity get pressed too deep and fail to make contact with each other.

An easy solution is to use a paper clip to very gently pry the metal ring up.

Be careful not to break the ring off! It is only attached by a very thin wire. Lift it evenly by only a small amount.

If adjusting the ring on the cartridge itself does not solve the problem, try the same fix with the battery itself. The ring hole is smaller so you may need a thinner paper clip. Remember to be gentle, these are very delicate pieces. It takes very little force to raise the ring slightly.

Most of the time this will solve the problem, assuming your battery is charged and your cartridge has oil in it. Happy Vaping!

Troubleshooting: How To Fix A Disposable Vape Pen

Disposable vapes are built for convenience, which makes a broken or improperly function pen all the more frustrating. Because returning defective vape pens is inconvenient and not always possible, consumers often look for easy fixes they can do themselves.

The truth is disposable vape pens aren’t really meant for fixing. They are self-contained devices designed to work easily right out of the package. Yet things can go wrong, especially with inferior vapes or improper usage.

How Long Do Disposable Vape Pens Last?

At a certain point, all disposables will stop working. They aren’t designed to last forever, but they are supposed to last long enough for all of the concentrates they house to be consumed.

Exactly how long a disposable vape pen should last depends on a few variables. The first is battery quality. Any premium pen uses high-quality batteries that should still run strong when you hit the last puff of cannabis extract. The best batteries for vape pens are Lithium-ion (Li-ion). They offer the longest-lasting charge without sacrificing power. Greentank uses Li-ion batteries for all our vape pens.

Another major factor is the fill size. It should go without saying that larger quantities of oil will yield more draws, which is why a .5ml fill generally produces about 225 draws, whereas a .25 ml fill tends to produce about 120-125 draws.

Temperature and length of draw further impact the number of draws a vape pen produces. Taking longer draws uses up more product per draw, and high temperatures use up product quicker.


Check Fluid Level

If your disposable vape pen is no longer producing vapor, the first thing to check is the fluid level. Many vaporizers have a window, allowing you to see how much product remains. If there is no oil in the window, it’s time to toss the pen.

If the fluid is empty before using the pen, that’s a separate issue. Concentrates may evaporate if they have been stored improperly or in extremely hot climates for a very long time.


High-quality vape pens use anti-leak technology. Yet, leaking can still occur, usually for the following reasons:

  1. Improper Storage: Cartridges can expand and ultimately leak when devices are stored at high temperatures for an extended time. To avoid this, we recommend storing disposable pens between 10˚-25˚C (50˚-77˚F).
  2. Handling: Vape pen manufacturers with poor quality assurance processes have greater risks of leaks. It’s easier for these devices to loosen, or for users to unscrew the caps by hand, causing the oil to leak out. Greentank uses press-down capping technology, ensuring the proper pressure and sealing to reduce the risk of leaks.

Dead Battery

Your disposable vape pen should come charged and ready for use. Yet even unused batteries don’t hold charges forever. Storing batteries in a cold environment causes them to drain faster.

Old or expired batteries eventually lose their charges, but this takes a significant amount of time. Lithium-Ion vape batteries, for instance, can take months to lose their charges.

Check your device’s indicator light to determine whether your battery is dead. Many disposables come with lights that show the status of their batteries. This feature is not yet standardized across the industry, but consumers would do well to opt solely for disposables with these lights so they can test the device’s battery functionality for themselves before making any purchases.

Burnt Taste

Flavor matters. Burnt tasting vapor is a sign that something is not right, either in quality or design. A common cause of burnt-tasting vapor is temperature settings that are too high for the concentrates. Lower temp vape pens prevent burnt tastes and create a richer, fuller flavor.

Temperature settings are not the only source of burnt vapor. Another important factor is the coil type. Most vape pens use either ceramic, quartz or wick coils . Quartz and wick coils apply heat directly to the cannabis extract. This makes for rapid heating, but also makes it easy to burn the fluid, resulting in suboptimal flavor.

The best vape pens on the market currently use ceramic core technology . Ceramic vape pens produce the best flavors and highest-quality vapors.

Prevent Issues With Premium Disposable Vape Pens

The most effective solution is prevention. Quality is at the core of troubleshooting disposable vape pen issues. Choosing premium vapes is the easiest way to avoid problems and consistently enjoy a premium, reliable experience.

Greentank is dedicated to providing a premium quality product and experience, using world-class design and the latest technological innovations.
