A 5,000mAh power bank with no fast charging and no built-in cable typically sells for $50 to $60 on Amazon. This Anker 20,000mAh power bank with an 87W output, a built-in USB-C cable that withstands 10,000 bends, and three charging ports just hit its all-time low at $47, off its $69 list price and the lowest price this power bank has ever reached on Amazon.

87W across three ports, 65W single port, MacBook compatible
The 87W total output distributed across three ports handles the full range of devices that travel with a serious mobile setup. A single USB-C port delivers up to 65W, which charges a 14-inch MacBook Pro to 50% in under 40 minutes and an iPhone 15 Pro to 58% in 30 minutes via the built-in cable. The second USB-C port and USB-A port cover simultaneous charging for a second phone, a pair of earbuds, or a Nintendo Switch without any of the ports throttling to a trickle. At 20,000mAh and 72Wh, the bank is TSA-approved for carry-on without any documentation or declarations.
