You were unlucky. There are very few chargers on the CPS network that have overstay fees for such a short time. My local ones are free and have no limit whatsoever. I also routinely get mid 40s kW which is enough to give me circa 45% additional charge in an LR in 45 minutes.On my recent NC500 trip the only one I got near 50kw was on Skye with yet another 45min limit the same as in Ullapool. The one in Grantown On Spey was completely dead despite the website saying otherwise. Braemar was the only one that didn’t have a time limit. There really needs to be more consistency. The Gridserve at John O Groats was the best non SuC.
