Sorry to bring the old topic but I am going thru the same thing now. I have 2017 with cigarette lighter in the left cubby. I bought a brand stinking new BMW ($$$) charger last year for my other bike and now I cannot use it for C650GT. I asked the local dealer and they said that many people complain about cigarette lighter type outlet. They offered to sell me an adapter which they make in the house. 20 euro later my charger indicates "Short / Reverse Polarity". Took it back, they rewired it, but still no luck.
I aslo tried today, and the outlet is working for usb cell phone charging when the ignition is on.
My plan is to install SAE fused direct to battery harness; Powerlet piece arrived yesterday.
It's a shame that I cannot use super-duper BMW charger. The only other connection available with the charger is alligator clips. I might come up with some kind of adapter SAE - BMW style female plug.
Thanks.
