Mellow Fellow Fillable Device 2ML

The Mellow Fellow Fillable Device 2ML is a refillable hemp vape built to pair with the Mellow Fellow THCA Terp Sauce Syringes 2G. It has the form factor of a standard disposable vape — compact, draw-activated, no buttons to configure — but with a 2ML refillable tank you fill yourself using the syringe. When the oil runs out, you refill it instead of replacing the device. The hardware stays. The oil rotates.

At $11.95 this is the one-time hardware purchase. The ongoing cost is the Mellow Fellow THCA Terp Sauce Syringe 2G ($18.95) — one syringe fills the tank completely. Available in four blends: Gas Candy (Euphoria), Polar Pop (Creativity), Pot Of Gold (Introvert), and Timewreck (Charged).

How to Set Up and Fill the Mellow Fellow Fillable Device

Important: Always fill around the center airflow tube — never down through it. The center tube is the air channel. Oil poured into it floods the coil, causes gurgling, and can permanently damage the device.

1. Charge before first use: Plug in via USB-C using a charger rated under 24 watts. Do not use Apple or Mac charging blocks — they supply excess wattage that can damage the device. LED pulses red while charging and turns off when full. Charge time approximately 45–90 minutes from empty.
2. Warm your Terp Sauce Syringe: Hold the syringe in your palm for 60–90 seconds before filling. Thick terp sauce oil does not flow freely at room temperature — warming it prevents air pockets and makes the plunger move smoothly.
3. Remove the mouthpiece: Pull or unscrew the mouthpiece from the top of the device to expose the fill port and the center airflow tube.
4. Fill around the center tube: Place the syringe tip in the space between the center airflow tube and the outer tank wall. Dispense slowly with steady plunger pressure. One full 2G syringe fills the tank completely.
5. Leave a 10% air gap: Stop filling at approximately 90% capacity. The small air space at the top creates a vacuum seal when you replace the mouthpiece.
6. Replace the mouthpiece: Secure firmly — do not over-tighten.
7. Wait 5–10 minutes: The ceramic wick needs time to fully saturate with oil before drawing. Drawing too soon causes a dry hit that can permanently damage the coil.
8. Start at low voltage: First draws at the lowest voltage setting to prime the coil and preserve the terpene character of the extract.

Frequently Asked Questions:

What oil do I use to fill the Mellow Fellow Fillable Device?

The device is designed to pair with the Mellow Fellow THCA Terp Sauce Syringe 2G. One syringe fills the 2ML tank completely. Available in four blends at DeltaCloudz: Gas Candy (Euphoria), Polar Pop (Creativity), Timewreck (Charged), and Pot Of Gold (Introvert). Only use compatible hemp concentrates — do not use nicotine e-liquid or oils not formulated for a ceramic coil vaporizer.

What is a refillable disposable vape and how is it different from a regular disposable?

A standard disposable arrives pre-filled and is discarded when the oil runs out. The Mellow Fellow Fillable Device works the same in your hand but the tank opens for refilling. When the oil is gone, you add more instead of replacing the whole device. The hardware stays in use across multiple fills — the only ongoing purchase is the syringe.

How do I avoid leaking after I refill the device?

Leaking is almost always caused by overfilling past 90% capacity, oil getting into the center airflow tube during filling, or a mouthpiece not secured firmly after refilling. Always fill to 90% — leave a small air gap at the top. Never put oil down the center tube. Replace and secure the mouthpiece immediately after filling. Store upright between sessions.

Why should I use the preheat function on the Mellow Fellow Fillable Device?

Terp sauce is thicker than standard vape distillate. In cooler temperatures the oil can become dense enough that the wick has difficulty drawing oil to the coil during the first few pulls. The preheat function briefly warms the tank at lower power before you draw, loosening the oil and ensuring the coil is properly saturated before it fires. Use preheat whenever the device feels weak on the first draw of a session.

Is the Mellow Fellow Fillable Device Farm Bill compliant?

When used with the Mellow Fellow THCA Terp Sauce Syringe 2G — hemp-derived, less than 0.3% Delta-9 THC — the complete setup is compliant with the 2018 Farm Bill. Must be 21+.
