The Anker Power Bank (20K, 87W, Built-In USB-C Cable) is a 20,000mAh portable charger that shares 87W across three devices and carries its own built-in USB-C cable for cable-free charging.

Distribute 87W across three devices, with a single device drawing up to 65W — enough to take a 14-inch MacBook Pro to 50% in under 40 minutes. The built-in cable charges an iPhone 15 Pro to 58% or a MacBook Air to 52% in 30 minutes, and the bank itself refills in about 1.5 hours with a 65W charger.

The 20,000mAh capacity keeps multiple devices going through travel days, and the integrated cable is built to endure over 10,000 bends for reliable charging and tidy storage.
