I doubt it, but don't quote me on that.
The 306 is compatible with the 510 models.
The
batteries are interchangeable, but each needs to use the cartridges meant for it.
I REALLY like to use my 306 atomizer with my 510 manual battery.
I use it for dripping
throughout the day at work, with empty cartridges.
At night I switch to my 510 atomizer and use the 510 cartridges.
