It's Halsey's second No. 1 on the tally and her first appearance since 'Badlands' in 2015.
Power debuts with 98,000 equivalent album units earned in the Aug. 27-Sept. 2 tracking week, according to MRC Data.
It's Halsey's second Alternative Albums ruler, after Badlands crowned the chart in its debut week (Sept. 19, 2015). Halsey has since scored prominent pop success (on her own and with the likes of BTS, The Chainsmokers and Khalid, among others); Power marks a revisiting of her alternative roots on a full album, thanks in part to production from Trent Reznor and Atticus Ross of Nine Inch Nails.
