The great majority of portable power banks on the market has a few USB-C power output (18/30/45/60W). In charging devices that require a high USB-C output, like MacBook Pro, it will take much longer than the average consumer wants to. SuperTank is able to fully charge a MacBook pro in just one hour and half.
Instead of adopting a cool design like other big names in the industry, the producers prefers a more compact and smart shape. Such effective design makes the powerbank easy to stand up on nearly any side for easy access to the ports.
Pledges are available on the crowdfunding campaign from $59 or £45 for early backers and general shipping is expected to start from June 2019.
