The company's chief Elon Musk hinted at the device in December, describing it on Twitter as a "solid metal snake".
After the firm revealed a video of the charger in action he joked that it "does seem kinda wrong".
At the moment the gadget is just a prototype and the company has no plans to sell it in the near future.

The 46-year-old Portugeuse will attend Sunday's Old Firm match against Celtic before starting work on Monday.
Under-20s coach Graeme Murty will remain in interim charge for a sixth game since Mark Warburton's departure.
"It is a great honour to join Rangers Football Club," said Caixinha after being released by his Qatari club Al-Gharafa on Friday.
"This club has a great history and tradition and I am proud to follow in the footsteps of legendary Rangers managers like Walter Smith, Graeme Souness and Jock Wallace.
"Rangers is a name that is known worldwide and I am looking forward to forging a positive relationship with supporters and meeting the playing squad and staff at the club.
"I know there is a lot of hard work ahead and I assure all our fans that I will do all I can to provide a winning and entertaining Rangers team."
Caixinha previously managed Uniao Leiria and Nacional in Portugal, and led Mexican side Santos Laguna to the 2014 Copa MX Apertura trophy, the 2015 Liga MX Clausura title and the 2015 Campeon de Campeones trophy, as well as the 2013 Concacaf Champions League final.
Before moving into management, he spent six years as assistant to Jose Peseiro at Sporting Lisbon, Saudi Arabian side Al-Hilal, Greek outfit Panathinaikos, Rapid Bucharest in Romania and the Saudi Arabia national team.
Caixinha, who speaks fluent English, earned some of his coaching qualifications at the Scottish Football Association's coach education centre at Largs.
"We are delighted to welcome Pedro to Rangers," said managing director Stewart Robertson. "We compiled a shortlist of high-quality candidates for the position but we knew after our initial meeting with Pedro that he was the right man to take this club forward.
"He is a man of great experience and authority and the board has no doubt he will help us achieve our long-term goals. I would like to thank the Rangers supporters for their patience throughout the process but we were determined to appoint the best candidate possible.
"I would also like to thank Graeme Murty for taking control of the first team. He will complete his duties at Celtic Park on Sunday before returning to his role with the Under-20s and Pedro will begin his work on Monday morning."
Murty has overseen Scottish Cup wins against Greenock Morton and Hamilton Academical, and a Premiership victory over St Johnstone, but league defeats by Dundee and Inverness Caledonian Thistle.
The Ibrox side are third in Scotland's top flight, six points behind Aberdeen and 33 off runaway leaders Celtic, who can clinch a sixth straight title this month.
Warburton, who led Rangers to promotion by winning last season's Scottish Championship, parted company with the club at the same time as assistant David Weir and head of recruitment Frank McParland.
McParland has since become director of football at Nottingham Forest.

ESPN  has been struggling as younger audiences choose outlets like Netflix and Amazon Prime over cable television.
In a statement president of ESPN, John Skipper, said though sports viewership was not diminishing cuts were necessary to keep a "competitive advantage".
Disney, which owns ESPN revised its profit expectations in August after the channel saw a decreases in subscribers.
ESPN gets money from cable companies when subscribers buy bundles that include the sport channel. As more people choose cheaper cable packages or opt for online subscription TV such as Netflix, ESPN is having to rethink its strategy.
Disney said in August it was considering selling access to ESPN directly to viewers in the way outlets like HBO and Showtime already do.
Most of us work to make money - and if it happens to be by doing something we love, we're considered lucky.
