I don’t have any figure, but it certainly wouldn’t be very much, or a large concern for a non-battery power setup like this.

FWIW one of the attendee at this year’s Pi Party had a Scroll pHAT HD as a name badge and ran it most of the day on a 2000mAh LiPo… well, I think it was the way he powered it, I don’t recall but would expect that sort of consumption for typical usage.

actually I hunted down his blog post on the subject and he had a 1000mAh running for about 4 hours - obviously that covers the Pi’s own consumption as well, but that gives you a rough idea what to expect anyhow.

… if of interest, here’s a link to Carl’s amazing project based on a Scroll pHAT HD: https://fortoffee.org.uk/2017/03/scroll-bot-and-pong/
