The FS M401 USB Passthrough is a must have item for anyone who is in front of a computer for long periods of time. Save your batteries for “on the go moments,” just plug one end of the passthrough into your USB port, connect the battery on the other end to your atomizer and use your personal vaporizer at full power for as long as you like! The passthrough also has an orange LED tip that lights up as you inhale. The FS M401 USB Passthrough has a long, retractable cable for ease of use and convenience.


Useful Tips:

Always keep the cartridge damp with Refill Liquid or use a fresh cartridge while using your passthrough. For those that use their personal vaporizer frequently, take occasional breaks between use to prevent the atomizer from overheating.
