Geek Slim 40K

The Geek Slim 40K is built for people who are tired of replacing a device every few days. Two firing modes, a 40mL prefilled tank and a rechargeable 650mAh battery — factory sealed, authentic stock, shipped fast from the U.S.

Key Features

Dual Mode: Regular Mode is rated for up to 40,000 puffs. Switch to Pulse Mode for a harder, warmer hit rated up to 20,000 puffs.

40mL Prefilled E-Liquid: One of the largest tanks in the disposable category, which is where the puff count actually comes from.

5% Nicotine (50mg/mL): Salt nicotine, as marked on the package.

650mAh Rechargeable Battery: Recharge and keep going, so the device runs until the juice is gone instead of dying with liquid still in it.

Dual Mesh Coil: Larger heating surface for cleaner flavor from the first puff to the last.

Adjustable Airflow: Tighten it for a cigarette-style draw or open it up for direct lung.

Smart Display: On-device screen showing battery and e-liquid level, so you know when to reorder.

Flavors

Banana Ice, Blackberry Blueberry, Grape Ice, Gummy Bear Ice, Strawberry Kiwi Ice, Strawberry Mango, Strawberry Watermelon.
