Charging Aqualung i330r without adaptor?

I am right now in Curacao, to start scuba diving (12. Oct 25). But have forgot my adaptor. Anybody that know:

• the pin out on the 4 charger pads in the i330r computer.
• where I can purchase the adapter in Curacao.
• if I can rent/borrow an adaptor in Curacao.

Any help is highly appreciated. (Yes, I do have a spare computer with me. And yes, it is stupid to forget the adaptor).
