Greentank performs a rigorous and multi-tiered quality control process for all of our manufactured products and product components. The process begins with our Incoming Parts Quality Control (IPQC) team inspecting all product materials and components to ensure they meet specifications before they are released to the assembly line. Next, we perform in-line tests on all critical components to ensure proper assembly and functionality. Once the product has been assembled, we perform multiple final quality control (FQC) checks to further ensure proper assembly and functionality as it pertains to customization, operation, packaging, and more.

Greentank 510-threaded cartridges are compatible with most 510-threaded batteries.

Greentank batteries come with USB charging connectors. Please read your provided instructions carefully to ensure you are plugging USB chargers into the correct outlets.

All Greentank vape pen batteries are engineered to last a minimum of 300 charge cycles before they need to be replaced.

The LED indicator light will blink several times to indicate a low charge. Your vape pen will also produce significantly less vapor when your battery is low.

The LED light on the USB charging connector will turn green when your battery is fully charged.

Yes, Greentank provides recommended post-filling transportation guidelines for all of our products. Please contact a Greentank rep to request an SOP for a specific product.

To remove any oil-residue build-ups from a Greentank cartridge, battery, or All-In-One pen, gently swab the surface with a Q-tip or cotton ball that has been lightly dipped in isopropyl or water. Greentank’s Snap Sticks are designed specifically for this purpose. They can be purchased here.

There is no standard answer to this question for multiple reasons:

• Temperature setting preferences
• Different oil formulation types
• Different oil formulation viscosities
• Unique user inhalation habits, including draw frequencies and lengths

You may experience a burnt taste if you are using a cartridge or an All-In-One vape pen with less than 5% of its oil remaining. In this instance, there is not enough oil re-saturating the heating core. Rapid and aggressive usage of vape pens can also lead to burnt tastes.

Cannabis oil and other hard concentrates cannot be vaped using e-cigarettes or vape pens designed specifically for dried cannabis flower. Likewise, dried cannabis cannot be vaped using e-cigarettes or vape pens designed specifically for cannabis oil. We cannot emphasize enough the importance of only purchasing regulated and tested cannabis products from compliant Licensed Producers, cultivators, and brands.

There is no standard answer to this question for multiple reasons:

• Differences in reservoir capacities
• Temperature setting preferences
• Different oil formulation types
• Different oil formulation viscosities
• Unique user inhalation habits, including draw frequencies and lengths

Pod-based systems are rechargeable closed-loop devices that allow users to interchange pre-filled oil pods that are compatible with specific battery types. Cartridge & battery units, on the other hand, are rechargeable open-loop systems that allow users to attach universal 510 cartridges to 510-threaded batteries.

All-In-One vape pens are disposable designs that house batteries and pre-filled oil reservoirs within a single unit.

Cannabis concentrates are often very thick or viscous. In some rare instances, the heating core can become oversaturated, which, can cause blockage of the airway, also known as a clog. Here are some helpful tips to clear the airway and get your vape running smoothly.

Clogged vape pens sometimes unclog themselves if you store them upside down after use.

If your push-activated pen doesn’t unclog, try a technique called “priming the cartridge”. To do this, you simply preheat your vape pen by turning on the battery, then pressing and holding the button for 5 seconds. Contact your point of purchase if this technique does not unclog your device.

If your breath-actuated pen doesn’t unclog, try using the “toothpick technique”. Gently insert a toothpick into your device’s mouthpiece as far as it will go. Repeat this process at least 3 times until the blockage is cleared. Contact your point of purchase if this technique does not unclog your device.

Your battery may not be connecting your cartridge for a few different reasons:

First, make sure your battery is fully charged.

Next, ensure that your battery and cartridge are compatible. Greentank batteries have 510 connector threads and are only compatible with 510-threaded cartridges, the most universal cartridge type on the market. Some batteries and cartridge types are designed with different threaded connectors and simply will not connect to 510-threaded hardware.

If you have confirmed that your battery and cartridge are compatible, make sure that you are screwing the cartridge clockwise into the battery. Be cautious to not overtighten the cartridge when screwing it into the battery. Overtightening can cause the anode to lose its connection point with the battery.

If the anode loses its connection point with the battery, you will need to extricate it. Here’s how you do it:

1. Identify the anode. It is the silver metallic component inside of the silicone gasket on the underside of the cartridge.
2. Next, place a toothpick or your fingernail under the anode.
3. Gently rotate the anode in either direction until it is slightly raised above the silicone gasket, approximately 1-2 mm or 0.04-0.07 inches above the surface.  Note: Do not fully pull the anode out of the cartridge.
4. Screw cartridge clockwise into battery lightly.

*Contact your point of purchase if your cartridge still won’t connect to your battery after attempting these troubleshooting techniques.

Ensure that your USB charging connector is fully screwed into the battery. Your battery will not charge if the USB charging connector isn’t properly connected.
