there really should be some sort of "seal of approval" created and dispensed to all vaping devices and equipment that meet pre-determined compatibility specifications..categories of equipment would include atomizers, battery connections and adapters for a start...
the issuers of the seal of approval would be some consortium of folks, immune from corruption mind you, that would test and measure all the equipment from those the desire the seal.....
examples:
If we only had someone who could come up with an approval seal for vapers.....????
Getting the folks that would be in the consortium shouldn't be too hard....they would measure and test all equipment and devices sent in for inspection and retain the gear for comparison purposes
