In Residential use if you want to avoid the ugliness and hassle of having that power lead trailing from your under the garage door or out of a window to your Electrical Vehicle, then how about installing a proper EV charging point. If you are starting out and have a requirement for only a 16A (3.6Kw) powered point then I would seriously consider installing a 32A (7.2Kw) capable circuit. One reason being is the extra costs for a larger 32A cable and protection accessories are relatively small compared to the overall installation labour cost to run a cable from the home Consumer Unit (Fuse Box) through the house to a charging point. Also your next vehicle or a change of use might benefit considerably with a 32A powered point so an upgrade would be less disruptive on the house and cheaper.
If you are thinking about the Tethered or Non Tethered choice, then certainly Tethered is convenient. No wet grubby cable to tidy up and keep in the boot. But if you change vehicles often or have guests to stay with other types of vehicles to charge, then Un Tethered has its benefits.
Some designs of Charging Points have an outside grade 13A socket built in as well. Useful for vacuuming the car or powering that lawnmower.
