Well I haven't actually tried any public charging points as I've plugged in at home with the granny cable at the weekend, so I couldn't really comment on availability. However, within range of Fareham there is only two sets of free charge points, one is a PodPoint at Tesco and the other is run by a eco/e-vehicle trader who will kindly allow you to use his rapid chargers for free if you ask him nicely
The only one that is truly rapid is the one run by EcoMan as I'm now calling him. The others are all 7kW equivalent to what you would have at home, somwhat negating their usefulness unless you want to sponge free leccy while doing your Tesco shop - it might just about cover your trip there and back.
There is one more 'free' but its at a local bistro so you would need to be dining there to make use of it - 3kW like using a granny cable, so maybe just enough to get you home once you've had your meal? Bear in mind 25% to 95% on my 64kWh leaf took 20 hours charge on the granny cable.
Other than that there is a handful of expensive charging points in some town centre car parks. Let's use an example, so the closest one for me in Fareham town centre is a mix of Type 2 (43kW), CCS (50kW) and CHAdeMO (50kW - and makes me think of
something like this ) but while they are rapid charge it's £1 connection fee then 30p/kWh, £10 overstay charge after 95 mins. So honestly the number and cost of them is still so crap I wouldn't be looking to rely on any of them at all. Roll on getting my home wall charger fitted.
