Tesla has thrown its weight to the power bank market - yes, power bank - with the introduction of the Power bank, a portable battery charger that should satiate your thirst for anything Tesla without actually buying any one of the automaker’s electric cars. The Powerbank takes the shape of the company’s supercharger monument that’s resting at the Tesla Design Studio. It features a single 18650 cell with a 3350 mAh capacity, enough juice to charge all recent iPhone models and micro-USB-equipped smartphones. The Powerbank also retails for $45, cheap enough for those wishing for one this Christmas to actually get one, provided they were able to before it sold out.
