All Kokay’s Maldito Dive Resort rooms have two pole “round” / “flat” outlets
Normal devices (without ground – so the polarized plug – round) can be used without adapter in your rooms. For CH/D/EU 220V plugs no adapter needed. Do you have 3 pin connector (e.g. some LapTop chargers): please bring an adapter from 3 pole “reduced” into 2 pole. Otherwise you could buy “on site” also adapters on your way to Malapascua in any bigger electric hardware store. (Please tell it to your driver of Kokay’s Maldito transportation service…)
FYI: Philippines has 220V / 60Hz (CH + EU: 220V / 50Hz)
(For batterie chargers [Akku / batterie] had hitherto been never a problem)
