Tesla is warning users about a popular "charging hack" that can allegedly result in shorter wait times at select Supercharger stations. The trick, which has been circulating within the Tesla community for at least a few years now, involves wrapping a damp towel around a Supercharger handle when charging. The idea is that the wet rag acts as a cooling agent, tricking temperature sensors inside the handle into thinking the system is running cooler than it actually is.
Some claim the hack can increase the charging rate, especially on hot summer days, resulting in a faster charge and less waiting around. Now, Tesla has issued official guidance on the matter.
According to the official Tesla Charging account on X, placing a wet cloth on a Supercharger handle does not increase its charging rate. In does, however, interfere with the system's temperature monitors and could lead to overheating or damage. Tesla advises against the towel trick to help ensure their systems can operate correctly.
[...] Inside EVs points to several instances that seem to refute Tesla's claim that the trick does not work, at least with older V2 Supercharging systems. One Tesla user put a damp cloth over the charging handle on a V2 Supercharger, which increased the charging rate from 60 kilowatts to 95 kW on a hot day. Another user plugged in at two percent stage of charge and reached 147 kW before thermal throttling kicked in at 34 percent and slowed the rate down to 58 kW. Applying a wet rag reportedly drove the charging rate up to 119 kW.
V3 and newer Superchargers utilize active cooling. According to Inside EV, the towel trick does not really help at all on these systems unless you are charging a Cybertruck.
Tesla owners would probably be best served to take the company's advice and not fool with the trick. Saving an extra few minutes simply is not worth the risk of damaging your vehicle or Tesla's equipment.

Highly unlikely you would ever get shocked.
These are made to use in all weather conditions including rain.
They have GFCI protection and sense the connection to make sure things are ok before they ever start charging.
If there are any anomalies the charger won't start or will stop if it's already charging.
There is always slim the possibility that all of the built in safeties could fail, but you would still have to get the electricity to jump a pretty long path to get to you... so you would have to have all the safeties fail AND have a damaged charger.... or be charging while doused in saltwater or battery acid or some other electrolyte.
They're really quite safe.......... most of the time. ;-)
