I am aware that Ecuador uses sockets compatible with the US/North American standard (source), but which type is more widespread: the ungrounded (type A, 2 pins) or the grounded one (type B, 3 pins)?
I'm asking because I usually use only one adapter and a multiple socket extension, which is very useful for older hotels with few power sockets, but requires a grounded socket.
Clarification: I'm not worried about the outlet not being grounded, as the devices I am usually connecting don't need that anyway, but the only multiple extensions available here (in Germany) have grounded plugs (which are also certified for higher currents), which can only be used with grounded adapters.
