Well, I recently came past an avant-garde 4 seat bench that had 220V sockets, so that’s what I added, not necessarily for bikes, one can charge your phone or sit and work on the laptop. A Stop & Go bike toolstand recently placed here had 2 sockets… In Rapino there’s a stand with 2 heavy duty 220v sockets. You need to push a button for few seconds and then the thing will charge for an hour. All for free, all of these bring your own charger. Maybe something like socket:220V=yes, no hit I had on TagInfo but they having been appearing all over the place here.
There’s always debate to map as separate node or as a feature of something. Whether cycle progs have a nose for them I don’t know.
Edit: Come to think the city here installed 10 4 spot covered charging stations for e-bike only with little lockers holding the charging cable where you can stick a device in for simultaneous charging. Over 1 year of operation and never ever seen a private e-bike charging there, but they have a secure bike locking system to slide steering bar in so your bike wont be ripped and that’s what peeps have been using them for to park their regular street bikes. No signs saying that non-ebike will be removed.
