The one in the Central Car Park CYC 70634 is the one that's very poor. The 7KW unit at Le Strange Arms, is the only other charger in Hunstanton. Admittedly if you persevere with the rapid in the Central Car Park, and you can get a few 5 or 10 minute charges, it does pump in at 40KWh, but you have to try and stop the failed charge, reset on the screen and try again. The app still says I'm connected and charging a couple of weeks later, and they've only just charged me!
