But you likely wouldn't buy a $45 battery pack with those specs if it weren't designed by Tesla when there are numerous cheaper alternatives. That's probably why the company made sure it looks like a Tesla product through and through. It was designed after Tesla Design Studio's Supercharger monument and wouldn't look out of place inside one of the EV-maker's cars. Unfortunately, you can't get one anymore, no matter how much you're willing and able to shell out $45 for the portable battery: it's already marked sold out on the company's website. You'll just have to cross your fingers and hope Elon Musk and his team decide to produce another batch.
