About this vaporizer
The Wulf SLK is a 510 variable-voltage battery from Wulf Mods that runs 510-threaded concentrate cartridges and wax atomizers in a pen format. Intensity is chosen via three colour-coded voltage levels: 2.8 volts (green), 3.4 volts (blue) and 4.0 volts (red). A triple click changes the level, five clicks turn the device on and off. Handy is the 15-second preheat function, which gently warms thick oils and concentrates before the actual draw begins. It charges via a supplied USB adapter. With its slim format and simple operation, the SLK targets users looking for a hassle-free, portable 510 battery with a bit of fine-tuning.

A 510 battery with variable voltage. It does not have its own vaporizer head, but instead powers connected cartridges or wax atomizers with a standard 510 thread.
Three colour-coded levels: 2,8 volts (green), 3,4 volts (blue) and 4,0 volts (red). A triple click changes the level, while five clicks switch it on and off.
It gently warms viscous oils and concentrates for 15 seconds before the actual draw begins — this helps prevent blockages and provides a more even first draw.
Wulf Mods does not state the exact capacity in mAh. The manufacturer recommends never charging the device for longer than one hour at a time.
Yes. The SLK uses a standard 510 thread and is therefore compatible with a wide selection of 510 cartridges and atomizers.
