Tesla owners place wet towels on supercharger handles to boost charge speeds

If you're concerned about spending money to charge your electric vehicle's battery, don't worry.

A Tesla owner shared an inventive way to enhance the Supercharger experience on social media, employing an unusual method.

The Tesla owner shared a tip for tricking the system in hot conditions. By simply using wet towels on Supercharger handles, some drivers claim to achieve faster charging speeds.

A unique tip on social media sparked debate within the Tesla community.

The Tesla owner uses wet towels put on the supercharger handles to get higher charging speeds.

During hot weather, some Tesla owners unexpectedly found a simple but effective way to enhance the performance of their Supercharger stations.

By placing a damp cloth on the charging handle, they can get more power from the charging station, saving valuable charging time. Skepticism remains over Tesla's ability to maintain high charging standards, but this lifesaving trick offers a glimmer of hope.

The wet towel trick has been circulating on Tesla forums and online communities and has sparked. 

One Tesla owner shared their experience on X platform: on a scorching day, they covered the V2 Supercharger handle with a damp cloth.

The result? The charging rate increased from 60 kilowatts to an impressive 95 kW. Meanwhile, Out of Spec Studios—an EV-focused channel—achieved an even better outcome.

On X platform, a user @Out_of_Spec, shared their experience with a unique trick.

The post read: "Another extreme wet rag supercharger test. Plugged in at 2% SoC - ramped up to 147kW as normal and thermal throttled at 34% down to 58kW.

Slapped that room temperature soaking wet rag and it climbed back to 119kW where it hit the internal charge profile limit. Amazing!" 

In the other post, they said, "It’s more useful to use this wet rag trick when plugging in at low SoC where the charger has to throw a ton of current to get up to ~150kW. If you plug in at 30% SoC, for example, you’ll need less current to reach 150kW as the pack voltage is already quite high." 

The post recently went viral on social media and sparked debate.

In the comment selection, another Tesla owner shared their experience with how this DIY solution can make a difference.

One person said: You cooled off the handle. Now you need to figure out a way to cool off the charge port.

A second wrote: I guess I need to bring a wet rag on road trips!

While a third commented: My mama always said electricity and water don’t mix.  

Someone else said: Yeah, this looks totally normal and right, just to save a few minutes!!!

However, the wet towel solution to increase charging speed has sparked safety concerns.

Furthermore, many Tesla owners have expressed shock about this hack, while some have raised safety concerns.

In fact, this unique tip isn't officially endorsed by Tesla, so proceed at your own risk."

This version maintains the original meaning while improving grammar and clarity.

One users said: It rains, no?

Another said: Surely this just cools the sensor, rather than cooling what the sensor is trying to measure? Is this really a good idea - something somewhere is going to be hotter than what the sensor thinks.

Someone else said: My mama always said electricity and water don’t mix.  

Not enough testing to determine yet. Another added. 

While the damp cloth won't harm the system, it's essential to end charging sessions through the car's screen or app before unplugging the handle.
