The STLTH ECO XL Disposable is the top tier of the STLTH ECO lineup. It carries 20mL of e-liquid. double the ECO BOX and over 3× the original ECO. It adds Boost Mode for a stronger hit on demand, keeps the LED screen and adjustable airflow from the ECO BOX, and recharges via USB-C with an 850mAh battery. Prefilled at 20mg/mL nicotine salt with 13 flavours. $30.25.
This is the largest STLTH ECO device. Three ECO models are available: the ECO ($16.50 / 6mL), the ECO BOX ($22.00 / 10mL), and this ECO XL ($30.25 / 20mL). The XL delivers the best value per mL and is the only one with Boost Mode. See the full 3-way comparison below.

What's New on the ECO XL
The ECO XL takes everything the ECO BOX introduced. rechargeable battery, LED screen, adjustable airflow. and adds two things: double the e-liquid capacity (20mL vs. 10mL) and Boost Mode, which lets you switch between Normal and Boost output with a button press on the screen side. Normal gives you a smooth, consistent draw. Boost cranks up the wattage for bigger clouds and a stronger throat hit.
If you've been using the ECO or ECO BOX and want a device that lasts significantly longer between replacements and gives you more control over intensity, the XL is the step up.
STLTH ECO vs. ECO BOX vs. ECO XL
All three devices are part of the same STLTH ECO family. budget-friendly disposables at different capacity and feature tiers. Here's how they compare side by side.

Bottom line: The ECO XL is the best value per mL in the lineup at $1.46/mL. nearly half the cost of the original ECO. It's the right pick if you want maximum capacity, Boost Mode, and the fewest device replacements. The ECO BOX is the mid-range option with solid features at a lower upfront cost. The original ECO is still the right choice if you need 0mg or want the absolute cheapest entry point.

Boost Mode
The ECO XL is the only device in the STLTH ECO lineup with dual output modes. Press the button on the screen side to toggle between Normal Mode and Boost Mode. Normal delivers smooth, consistent flavour with lower vapour output. Boost increases wattage for bigger clouds and a stronger throat hit. useful when you want more intensity without switching devices. Boost Mode will consume e-liquid faster, so expect slightly shorter overall device life when using it frequently.
Who Is the ECO XL For?
The ECO XL fills the gap between budget disposables and premium high-puff devices. It's built for vapers who go through devices quickly and want more capacity without jumping to the $30+ premium tier like the STLTH 8K PRO or Titan Max 50K. At 20mL and $1.46/mL, it lasts significantly longer than the ECO or ECO BOX and costs less per mL of e-liquid than either.
Frequently Asked Questions
What's the difference between the STLTH ECO, ECO BOX, and ECO XL?
All three are STLTH ECO disposables at different tiers. The
ECO ($16.00) is a basic 6mL non-rechargeable disposable. The
ECO BOX ($22.00) upgrades to 10mL with USB-C charging, LED screen, and airflow control. The
ECO XL ($29.25) doubles capacity to 20mL and adds Boost Mode. The XL offers the best value per mL at $1.46 vs. $2.20 (BOX) vs. $2.67 (ECO).
Does the ECO XL have Boost Mode?
Yes. the ECO XL is the only STLTH ECO device with Boost Mode. Press the button on the screen side to toggle between Normal Mode (smooth, consistent) and Boost Mode (stronger hit, bigger clouds). Neither the ECO nor the ECO BOX has this feature.
Is the STLTH ECO XL rechargeable?
Yes. The ECO XL has an 850mAh battery that recharges via USB Type-C. This ensures you use the full 20mL of e-liquid. The original ECO is the only model in the lineup that is not rechargeable.
Does the ECO XL come in 0mg?
No. The ECO XL is only available in
20mg/mL. If you need a 0mg option, the original
STLTH ECO is available in both 0mg and 20mg.
How long does the STLTH ECO XL last?
With 20mL of e-liquid, the ECO XL lasts substantially longer than the ECO (6mL) and ECO BOX (10mL). Duration depends on draw length, frequency, and whether Boost Mode is used. moderate users can expect 1–2+ weeks of use per device.
How does the airflow control work?
There's an adjustable airflow mechanism on the device. Open it for a looser, airier draw or close it down for a tighter, more restricted mouth-to-lung pull. Adjustable on the fly. no menus or settings.
What does the LED screen show?
The screen displays e-liquid level and battery level in real time, so you always know how much is left. Both the ECO BOX and ECO XL have this feature. the original ECO only has a basic puff indicator light.
