To use the Portavb, remove the lid and place on a table or tray (TIP if you flip the lid over and use it as a base, it will stick to any magnetic surface and will keep it steady) use your vape and when you have finished use the spike inside the Portavb to remove any AVB. 

Place the magnetic lid back on and off you go!

Portavb has a built in strong N54 diametrically aligned top magnet that will hold and cool your dynavap or any metal parts.

Portavb fully dissasembles for easy cleaning. Wipe with ISO and air dry.
