Six months a year on the road in the van, EV towing it, so I've plugged this same 15A portable charger into more caravan park outlets than I could count by now. Most of the time it seats in fine, firm click, no drama. But every few parks, especially the older Big4 sites, it's a proper wrestle to get the plug to sit right, sometimes I'm holding it in at an angle just to get power flowing.
Always assumed 15A blue outlets were all built to the same AS/NZS 3123 standard regardless of who installed them or when. Is that actually true, or is there enough tolerance in the spec that some manufacturers run looser or tighter than others? Or is it simpler than that and I'm just finding the outlets that are worn out from twenty years of caravan fridges and kettles going in and out of them. Genuinely don't know which it is.
