Though the electric vehicles (EV) maker Tesla Inc. (TSLA) continues to face a variety of issues for its primary stream of business, the company continues to taste success in exploiting its brand equity. (See also: What Drives Consumer Demand for Tesla?)

Continuing to diversify its offerings and keep the market abuzz with its brand, the Palo Alto, California-based carmaker recently introduced a portable, wireless smartphone charger on its website in the "Lifestyle" section. However, the $65 gadget quickly disappeared as shoppers jumped on to buy the limited inventory. Within less than a day, the wireless smartphone chargers were sold out.

Mediocre Specs Vs. Brand Value

As for the product specifications, the with 6,000 mAh Tesla charger supports both wireless and wired charging. It supports 5W of wireless charging and 7.5W of wired charging output. Available in black and white, it supports USB-A or USB-C charging capability. The device is also backed with an internal battery that can be charged with a USB-A cable from any standard USB port, and is capable of providing 21 hours additional talk time or 18 hours of additional web browsing.

Interestingly, other brand chargers with better specs are available at lower prices, and it appears that the Tesla brand continues to retain its appeal and interest among the buyers. American technology news and media network The Verge cites other comparable products, like Anker’s 10,000 mAh PowerCore charger that has 12W of output charging but no wireless charging capabilities available at around half the price of Tesla chargers. Among wireless chargers, there are others like RAVPower offering 10,400 mAh power with 10W of output at around $50. Buyers flocking to get the Tesla branded chargers are not “buying this for the specs or because they’re price-conscious” but for the Tesla logo, said the tech site. The product appeals to those who are looking for the convenience of both wired and wireless charging in the same device at a moderate price of $65.

Tesla claims that the chargers are "powered by the same cell found in many of the batteries of our vehicles." However, the company did not confirm the number of devices that were sold, or whether it plans to add another lot of chargers for sale in the near future.

Beyond selling charging supplies and vehicle accessories for its cars, Tesla has been active in the online marketplace with a range of branded merchandise. It includes apparels like jackets, hoodies, tees, sweatshirts and hats, and other accessories like collectibles (miniature models of Tesla cars), toys, drinkware, power banks and desktop chargers.
