How to Refill Lost Mary MO20000 Pro

If you’re using the Lost Mary MO20000 Pro, you likely appreciate a device that offers powerful performance. But at some point, you may wonder: Can I refill it? While the manufacturer markets the device as disposable, some users do attempt refilling. Below is a detailed, step‑by‑step guide on how to attempt a refill safely, along with tips, caveats, and best practices — with the understanding that results may vary and refilling may void any warranty.

1. Know Your Device & What “Refill” Really Means

Before you dive in, it’s essential to understand what you have. The Lost Mary MO20000 Pro is listed with features like up to 20,000 puffs, adjustable wattage from 13 W to 25 W, Type‑C charging, dual‑mesh coil, and airflow adjustment.

However, according to the brand’s website, “Only a few editions allow refilling.” In other words, most units are not meant to be refilled. If you attempt a refill, you should proceed with care and realistic expectations.

Why this matters:

       •  If your device has a sealed tank or no visible fill port, opening it may damage the battery, cause leaks, or bypass built‑in safety protections.

       •  “Refillable” in this sense means a limited ability to add e‑liquid, not an extensive rebuildable system.

       •  You may shorten the life of your device or reduce performance.

2. Inspect the Device for a Fill Port

If you’re determined to attempt a refill, begin by inspecting the device:

       •  Look for a small silicone plug or tab on the side or bottom of the device. Some discussions mention a fill port located behind a removable silicone plug.

       •  Make sure the device is powered off (if it has a power button) and disconnected from a charger.

       •  Clean the area around the potential fill port — any debris or lint may interfere with sealing properly.

3. Choose the Right E‑Liquid

Assuming you’ve found a fill port and plan to refill:

• Select an e‑liquid compatible with high‑nicotine salt format (if the device originally used that). The MO20000 Pro is typically sold pre‑filled with salt nicotine.
• Avoid overly thick (high VG) liquids that may not wick properly in the original coil/wick design.
• Make sure you’re familiar with the laws and regulations in your state concerning nicotine products.

4. The Refill Procedure (Step‑by‑Step)

Here’s a general procedure for attempting a refill:

      1. Remove any mouthpiece, cap, or external cover to access the fill port.

      2. Gently open the silicone fill plug — use a small tool or your fingernail, but avoid excessive force.

      3. Slowly inject or pour the e‑liquid into the reservoir. Fill just below the top edge of the tank, leaving a small air gap to reduce the chance of leakage.

      4. Once filled, re‑insert and press down the silicone plug firmly to reseal the port.

      5. Let the device sit upright for 5‑10 minutes to allow the coil to fully soak (wick saturation). This helps prevent burnt hits.

      6. After waiting, start with gentle draws (short puffs) to test whether vapor production is normal.

      7. If all seems well (no leaking, good vapor, normal flavor), you may proceed with regular use.

5. Post‑Refill Care & Monitoring

After your refill, keep an eye on performance:

       •  Leaks: If e‑liquid seeps out of the mouthpiece or base, stop using the device and clean the area.

       •  Flavor changes: A burnt taste often indicates the coil was dry or overheated.

       •  Battery performance: Since the Lost Mary device is rechargeable via USB‑C (on Pro models), monitor whether the battery holds charge as before.

       •  If you notice battery swelling, overheating, or any unusual behavior, discontinue use immediately.

6. When Refilling Isn’t Worth It

In many cases, users find that:

       •  The sealed design is meant for one‑time use. Opening it may lead to instant performance degradation.The cost/time of cleaning/monitoring may outweigh simply replacing the unit.

       •  Warranty and safety protections may be voided.

If you decide not to refill, you might consider using the device until performance drops and then replacing it. Many retailers offer the Lost Mary MO20000 Pro or similar devices — for instance, you can check availability via specialist resellers.

7. Safety & Legal Reminders

Refilling a device not explicitly designed for it carries risks. Keep these in mind:

       •  Never leave a charging device unattended or charge overnight if it’s a rechargeable model.

       •  Keep e‑liquid and devices out of reach of children and pets.

       •  Dispose of used devices properly according to local e‑waste regulations or battery‑recycling schemes.

       •  Be aware of the legal age and regulations for nicotine products in your jurisdiction.

What the Retailer Says & Where to Buy

If you’re interested in sticking with the official route, trusted retailers like LostMaryDirect.com carry the MO20000 Pro series in dozens of flavor variants. Their product listings clearly state: “Can You Refill Lost Mary MO20000 Pro Disposable Vapes? No… they are not designed to be refilled.”
By purchasing directly from a verified source, you get:

       •  Authentic product (not counterfeit).

       •  Full flavor selection (from “Blue Razz Ice” to “Rocket Popsicle”, etc.) 

       •  Full manufacturer/retailer support if issues arise.

9. Final Thoughts

Refilling the Lost Mary MO20000 Pro can be tempting — especially if you’ve found a good flavor and want to extend usage. However, because the device wasn’t explicitly built as a refillable system, you should proceed cautiously, understand the limitations, and be ready to accept trade‑offs in performance or reliability.

If you choose to go ahead, inspect carefully, refill slowly, allow for proper saturation, and monitor performance closely. And if you prefer simplicity and guaranteed performance, replacing the unit when it’s worn may be the better path.

Whatever you decide, stay safe, follow regulations in your area, and enjoy a smooth vaping experience.
