I stopped by the Kahala Aloha Mini Mart on my way home (on my bicycle) Monday and they now have a Level III charging station. It will be ready for use on Wednesday (they are having a ceremony at 10:00 am). There is also one available at the Aloha Mini Mart in Waipio and the Shell in Kailua. I've confirmed the Waipio one is open but don't know for sure about the Kailua one. I paid extra for the level III capacity so I'm happy to finally have some available on the island! Apparently they will be free during an introductory period (I'm not sure how long that will be).
