RAVPower Xtreme 23000mAh
Unfortunately, the RAVPower Xtreme 23000mAh is currently not available anywhere. Not even via Amazon. Unfortunately, this powerbank is one of the few that has a DC output to charge the Surface Pro 4 and also looks reasonably good. Is it possible for you, dear Digitex team, to include this in the range in the foreseeable future?
