Jason that last as confused me
Sorry. I didn’t realise that my first post that was supposed to reply to @oscarmax ended up replying to you. My reply to you should have said that the IP rating is 55 which is the same as the Ohme charger.
Thats fine, must of missed it sorry!
The RamTouch extension cable comes in 7 & 22kWh. If your use will soley be for extension purposes, get the cheaper 7kWh.
It will do no harm to wrap where the extension joins to the Ohme in Self-amalgamating tape on the connecting bit. This will make it fully waterproof 🙂
