How to Use the Eco 2in1 Refillable: Official Step-by-Step Guide
The Eco 2in1 Refillable stands out as a revolutionary dual-flavor, refillable vape system, engineered for personalized vaping and long-lasting performance. Its core appeal lies in the ability to enjoy two distinct 10ml e-liquid flavors in one device, paired with intuitive operation. Below is the step-by-step tutorial with enhanced focus on the filling hole’s precise location—a critical detail for error-free use.
What You’ll Need First
- 1 x Fumot Eco 2in1 Refillable (unboxed from its protective pouch)
- 10ml e-liquid bottles (mandatory: flavors must match the labels printed on the device)
Step 1: Remove the device from the pouch.
Begin with the foundational unboxing step:
- Locate the sealed, protective pouch that houses the Eco 2in1 Refillable.
- Open the pouch and remove the device in its entirety.
This step ensures your device is free from dust and moisture before you begin the critical setup and refilling process.
Step 2: Lift the drip tip upward and rotate it 90° to see the black silicone plug. Open the black silicone plug to display the filling hole.
This step is where you’ll access the precise location of the filling hole—pay close attention to avoid misalignment or leaks:
- Grip the drip tip (the top mouthpiece of the device) firmly and lift it straight upward to detach it from the device’s main body.
- Rotate the lifted drip tip 90 degrees clockwise or counterclockwise; this action exposes a black silicone plug situated directly on the top surface of the device’s tank compartment (the central area where the drip tip attaches).
- Peel back or lift the black silicone plug to fully reveal the filling hole, which is positioned directly beneath this silicone plug on the tank’s top surface—this is the only port designed for e-liquid injection.
Critical Note: The filling hole is recessed slightly within the tank compartment, making the black silicone plug its only cover—never attempt to inject e-liquid into any other opening on the device.
Step 3: Before filling, ensure the flavor of the 10ml e-liquid bottle matches the flavor labeled on the device, then inject the liquid accordingly.
With the filling hole fully exposed (at its location beneath the opened black silicone plug), follow these steps for precise refilling:
- First, cross-verify that the flavor of your 10ml e-liquid bottle matches the flavor label printed directly on the device’s tank adjacent to the filling hole. For dual-flavor use, confirm each e-liquid matches its corresponding tank’s label (the device features two separate tanks, each with its own filling hole in the same location—beneath its respective black silicone plug).
- Position the nozzle of your e-liquid bottle directly over the exposed filling hole (the port revealed in Step 2, beneath the black silicone plug).
- Slowly and carefully inject the e-liquid into the filling hole, taking care not to overfill the tank—stop when the e-liquid level is just below the rim of the filling hole to prevent leakage.
- After filling, press the black silicone plug firmly back over the filling hole to seal it completely.
This strict focus on the filling hole’s location and flavor matching ensures optimal performance and prevents flavor contamination between the device’s dual tanks.
Step 4: Lift the drip tip upward, then twist it to switch flavors.
Leverage the device’s dual-flavor design—still centered on the same top compartment where the filling holes are located:
- Lift the drip tip upward from the device’s main body (the same motion used to access the filling holes in Step 2).
- Twist the drip tip to the left or right to align its internal airway with the filling hole/tank of your desired flavor. The device’s transparent tank design lets you clearly see which filling hole/tank the drip tip is aligned with, ensuring you select the correct flavor.
- Press the drip tip back down firmly to lock it in place over the chosen filling hole/tank.
This design ties the flavor-switching mechanism directly to the filling hole locations, making it easy to associate each tank with its corresponding flavor.
Step 5: Remove the silicone drip tip and bottom sticker before use. When vaping, the screen displays battery level and brand logo, and the tank is lighted.
Complete your setup before first use, with a final check of the filling hole area:
- Double-check that the black silicone plugs (covering both filling holes) are securely closed, then remove the protective silicone cover from the drip tip itself (a separate protective layer from the filling hole’s silicone plug).
- Peel off the insulating sticker from the device’s bottom base—this sticker prevents accidental activation during shipping.
- Once prepared, take a gentle draw from the drip tip to activate the device:
- The digital screen on the device’s front will display the current battery level and Fumot’s brand logo.
- The tank (including the area surrounding the filling holes) will light up, visually confirming the device is active and the chosen flavor’s tank is in use.
Key Details From the Eco 2in1 Refillable Product Page
To maximize your device’s lifespan and performance, keep these details in mind—all tied to protecting the filling hole and dual-tank system:
- Dual 10ml Tanks: Each tank features its own filling hole (located beneath a dedicated black silicone plug), totaling 20ml of e-liquid capacity.
- Type-C Charging: A port on the device’s base lets you recharge the built-in battery, ensuring you use every drop of e-liquid you inject into the filling holes.
- Leak-Proof Design: The black silicone plugs covering the filling holes are engineered to create an airtight seal, preventing e-liquid from escaping during use or transport.
