それは困りましたね。
事情は理解できます。
PSEマークが付いたアダプターは日本でも調達できるのですが、
8.4V、2Aの規格のものは一般的ではないので調達することが出来ません。
alibaba.comで少し探してみましたが、MOQが100個の業者もありました。

いかがですか?100個程度であれば先に購入出来ます。
I understand your situation.
I can get an adapter with PSE mark in Japan, but I can not obtain the one with .4V、2A standard.
I searched on alibaba.com website, and I found a distributer who has 100 MOQ.

What do you think ? If 100 pieces or so, I can buy them first.
An adapter with PSE mark can be procured in Japan but for nonstandard ones like 8.4V and 2A are not available.
I have just searched in alibaba.com and there was a contractor with 100 MOQ.
Would you like to consider? You could purchase 100 in advance.
I understand the situation.
We can supply an adapter with PSE mark on, but the one with 8.4V, 2A standardized one is not common, so we can't supply it.
I did some research on alibaba.com, but there were companies that ask for 100 MOQ.
How would you like it? We can purchase them ahead if around 100 of those works for you.
