Naming          “WA” stands for “Wonpro Adapter”. The suffix characters ‘A’, ‘B’, ‘C’ after the number are mostly based on our own production history. We tried, but there is no unified consistent meaning on how this suffix is used.

WA-9             This is the Schuko type grounded plug adapter - its grounding is the flat metal on the bottom and on the side. Half of the WA-9 plug adapter is to be buried inside the recessed outlet. It uses the larger pin size: 4.8mm, 4.8mm. Note that WA-9 is specifically designed to meet the requirements of both Type E and Type F outlets:

·               Type E outlet (ground contact at the bottom, for France)

·               Type F outlet (ground contact on the side, for Germany)

In other words, WA-9 is used in Germany, France, and their countries they occupied during the colonial time - i.e., WA-9 is used for most of the continental Europe.

WA-9A          Ungrounded, smaller pin size: 4.0mm, 4.0mm. To be used with non-recessed outlets.

WA-9B          Ungrounded, bigger  pin size: 4.8mm, 4.0mm. To be used with non-recessed outlets.

WA-9C          This is the new EU plug (European Union plug). It has the extra inlay plastic to connect to a recessed outlet.
The idea behind the EU plug is to use only the common parts among all types of European plugs so that it can be used everywhere in Europe. It does so by:

·               Remove the grounding pin (the most uncommon part)

·               Use the smaller 4.0mm pin size

As a result, WA-9C can be used in Italy, but with no grounding. Similarly, WA-9C can be used in Germany, but with no grounding and with a slightly loose connection (pin size is 4.0mm, not the Schuko 4.8mm). Note that due to the unique design of the UK outlet, however, WA-9C can NOT be used in UK.

WA-10L        South Africa uses both WA-10 and WA-10L. Our customers have told us that WA-10L is now more popularly used in South African.

WA-11 can not be used with its recessed outlet (too short).

WA-11A        The inlay Switzerland plug adapter for its recessed outlet.
WA-11A can be used with its non-recessed outlet, but with slightly loose connection (smaller surface contact).

WA-14           The Israel plug adapter with round pins

WA-15           The Israel plug adapter with flat pins

We have customers buying both WA-14 and WA-15 to use in Israel. We have no information about which model is more popular in Israel.
 

WA-16           The old style of grounded Australia/New Zealand/China plug adapter.

WA-16N        The new plug adapter required by Australia.
WA-16A is exactly identical with WA-16 except its two power blades are half way covered by plastic - to provide higher safety protection (i.e., following the same design idea of the UK plug). Note that WA-16N can be used wherever WA-16 is used.

News Update: The Australia government is now enforcing this new standards!
