ISTICK X40 3000MAH BOX - ELEAF

iStick X40 3000mAh Box - Eleaf

The iStick X40 is the 2026 version of a box family that vapers have seen for ten years: a format that fits in the palm of your hand, everything is controlled with one hand, and nothing superfluous around it. Eleaf has calibrated it for MTL vaping, which stays close to the gesture of a cigarette, with a range of 5 to 40 W that is more than enough for a clearomizer with a high-resistance coil.

Its built-in 3000 mAh battery charges via USB-C at 2 A, so you don't have to leave it plugged in overnight, and the 1.05-inch TFT screen displays large enough to read at a glance, with five themes to choose from. The small on/off switch on the side is a detail you'll come to appreciate: the box won't turn on by itself at the bottom of your bag.

Why choose the iStick X40?

• 5 to 40 W range: the right setting for daily MTL vaping
• 3000 mAh internal battery, two to three days of autonomy depending on your draw
• Fast 2 A USB-C charging, no need for an external battery charger
• 1.05-inch TFT screen with five display themes
• Physical on/off switch to store it without surprises
• Firmware updates via PC, so the box doesn't age on the software side
