How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

The Typhoon Pro is one of the most widely sold NACS-to-CCS1 adapters, and A2Z's spec sheet is more detailed than most. It also says, plainly, that the UL 2252 certificate is not yet issued. We have not tested one; figures come from A2Z's product page, linked at the foot of this page.

The two temperature sensors

A2Z describes a two-stage design: the first sensor derates charging when it reaches a set temperature, and the second halts charging. Charging can resume once the temperature normalizes and the adapter is reconnected. It is a sensible design -- but a design is not a certificate.

The certificate, and the authorization question

A2Z lists its UL 2252 certification as in progress, with the tests passed and the certificate to follow. Separately, A2Z's page notes that third-party adapters, including its own, are not currently officially authorized for use on Tesla Superchargers. Both are the maker's own words, and both are reasons to check your automaker's guidance before buying.

Our view

Until the certificate is published, the Lectron Vortex Plus is the certified third-party alternative -- and your automaker's own adapter, if it offers one, comes first. How to read certification wording.
