Anker 20,000mAh 15W power bank on sale at Woot for about $21.60

Anker's PowerCore 20000mAh 15W power bank, with a USB-C and a USB-A port, is on sale. Two deal sites reported the offer on 7 and 11 November 2026. Both give a base price of $26.99.

The larger saving comes from Woot, which sells the bank through its app. According to Slickdeals, an extra 20 percent off in the app brings the price to $21.59. Its headline gives $21.60, so the exact final figure varies slightly. The report says shipping is free for Amazon Prime members, who must log in to see the offer.

TechBargains listed the same bank at $26.99 without an app discount. Its page was mostly charts of sales per hour and per day, so it gives little detail on the offer itself. Neither source states how long the deal will run or how much stock is available.

Readers who want a spare battery for phones, earbuds or other USB devices may find this a useful price. Still, the reports differ on the final figure, and the app discount may need a login. Check the total at checkout before buying, and compare with other offers on similar banks.
